History VideoGame / Survivio

* DropTheHammer: The Sledgehammer and Stone Hammer (the latter being exclusive to certain events) are slow but powerful melee weapons, which deal massive damage to items, allowing them to smash crates in one shot as well as being one of the few ways to destroy Eye Blocks.

''[[https://surviv.io Surviv.io]]'' is a top-down shooter [[BattleRoyaleGame battle royale]] IoGame. Up to 80 players spawn at random points on an island, where they must search for weapons and items, and kill each other. Last player or team standing wins.

* BladeOnAStick: The Naginata can be found in the Teahouse, though it may sometimes be replaced with a katana. It is powerful, and has a great reach, but also swings slower than most other melee weapons.

* AuthorityEqualsAsskicking: Played straight during the 50-50 mode, as the players who become team leaders instantly get a very powerful gun (An-94 burst-fire machine gun for Blue leader, Super 90 long-range shotgun for Red one) with a ton of ammo and 8x scope to pick off enemies from long range, a Flare Gun to drop supplies for the allies, machetes for melee, tier 3 armor, helmet and backpack, and adrenaline permanently set to max. Lieutenants get tier 3 equipment along with 4x scopes, powerful [=M4A1=]-S weapon, and doubled magazine sizes for all their weapons.

* AnAxeToGrind: Axes are the most common melee weapon around: you can find them stuck in the tree stumps, they'll occasionally be present inside a sealed container in an underground bunker, and a bloodied axe may sometimes be mounted on a cabin's wall in place of a shotgun. It's very much possible to cut down someone unarmed or wielding a pistol/low-powered [=SMG=] indoors, but you are still better off with a weapon out in the open. Its greatest strength is in allowing you to open containers much faster, thus saving your precious seconds in this fast-paced game.

** Olive: .308 Subsonic. Only found in the Airdrop containers next to the [=AWM=]-S sniper rifle, which is also the only weapon that uses it.

* BladeOnAStick: After the March 21, 2019 update, a Naginata can be found in the Teahouse, though it may sometimes be replaced with a katana. It is powerful, and has a great reach, but also swings slower than most other melee weapons.

* EdibleAmmunition: Potato mode has, obviously, weaponized potatoes in two forms: a throwable potato which deals small damage but more importantly causes the target to drop an item, and a Potato Cannon which fires exploding potatoes.

* BottomlessMagazines: Played straight for the Potato Cannon in the Potato Mode, which has an ammo capacity of 4, but will regenerate its potatoes indefinitely (and is also the only weapon in that mode that doesn't get randomly switched after you kill someone with it). Averted for everything else.
** The game had eventually introduced Endless Ammo perk for some of its special modes, which is extraordinarily powerful when paired with either LMGs or the weapons using extremely rare ammo like the Deagle or [=AWM-S=]: the lucky player can suddenly spam these weapons, and even shooting offscreen in the hope of hitting something suddenly makes sense as a strategy (unless it's Potato Mode, in which case you'll probably accidentally destroy a potato and have your cool weapon turned into something worse). The Tank class in the class-based mode has this perk by default, and their class-specific crates drop [=DP-28=] LMG to go with it. Moreover, Tanks can also allow their squadmates to get all the ammo they find, since they themselves won't need any of it.
* CombatMedic: In 50 vs. 50 mode, the Medic role grants the player a Bonesaw melee weapon, top-tier armor, fully stocked medical equipment, and the unique ability to share the effect of healing items with nearby players and revive multiple players at the same time.
** The class-based mode also features the "Medic" class, which even has the so-called "Combat Medic" perk. However, rather than letting the player heal others, the perk instead boosts their speed when they heal themselves with bandages or medkits. It is also paired with Windwalk, which raises speed when the player gets damaged, with the end result of letting the medic reach truly insane speeds. Not only can they thus dodge gunfire better than anyone (with the possible exception of waterborne Scouts), but they are also able to immediately close the distance and go for melee with their bone saws, with frightening effectiveness.
* CombatResuscitation: In duo and squad mode, players who run out of health are left to crawl on the ground, until they either get finished off by the enemies, bleed out on their own, or are revived by their team-mates.
** An "Auto-resuscication" perk was eventually added into some modes. It is possibly the single rarest perk in the game, and is obviously enormously useful, though it still requires for the player's opponents to be distracted by either their teammates or another threat for long enough to not notice them crawling away to some bush and then reviving themselves.

* FryingPanOfDoom: A very rare item found in airdrop crates. The frying pan has a longer range than most other melee weapons, very strong damage, and can deflect bullets while on your back.

* HandCannon: The legendary Deagle is one, as well as the Peacemaker revolver in the Desert mode. Fittingly, both of them are limited to their own, specific ammo type that's very hard to come by.
** The [=P30L=] pistol added in 2019 possesses high accuracy, a good rate of fire and 15 ammo - the same amount as an [=M9=], while dealing damage that's closer to Deagle levels.

* InfinityPlusOneSword: Some guns are considered the best:
** The [=AWM=]-S, only found very rarely in airdrops, is a sniper rifle that deals 180 damage per shot, making it a OneHitKill against targets that do not have good armor.

** The strongest melee weapon is the [[FryingPanOfDoom frying pan]]. Found rarely in airdrop crates, it boasts the highest range and damage per hit of any melee weapon (though its swing rate is slower). However, it is actually most useful when not equipped at all: if you keep it holstered, it acts as a shield for your back, something which no other melee weapon can do.

* RegeneratingHealth: Health regeneration requires adrenaline, which is gained by using soda or pills. During the 50 vs. 50 matches, the two players lucky enough to be chosen as their respective team's leaders get no increased health, but their adrenaline is always at the maximum possible state, letting them move faster and regenerate health quickly.
** The ''Film/JohnWick''-inspired Clubhouse also has the steam baths in its basement, and simply standing in the steam will regenerate your health.

** Averted. [=OT-38=] revolver is usually considered the second-worst pistol-type weapon in the game, and either the second- or third-worst weapon in the entire game (depending on one's opinion on the similarly controversial M1100). The few players who got good with M9 and its "shoot as fast as you pull the trigger" fire rate outright consider it the worst weapon.

* TreeCover: Hiding in the bushes amounts to this.
** "One with Nature" perk outright allows those possessing it to move through trees as if they didn't exist, which allows allows them to stand inside the trunk indefinitely, and even shoot from there. This is especially useful for the Scout class in the class mode, who combine this trait with the "Small Arms" one (a straight-up size reduction at no cost), thus making them essentially undetectable inside trees.

''[[https://surviv.io Surviv.io]]'' is a top-down shooter battle royale IoGame. Players spawn at random points on an island, where they must search for weapons and items, and kill each other. Last player or team standing wins.

* BattleRoyaleGame: 80 players must search for equipment and kill each other until only 1 remains.

** Yellow: The most common 9mm ammo, used by most of the starting guns: all of the pistols (besides Deagle), MAC-10, MP-5 and UMP-9. Players generally stop using these if they reach the late game, though the rare Vector [=SMG=] is an exception.

** Blue: 7,62 ammo. Used by the [=OTs=]-38 revolver, AK-47, [=SCAR=]-H, Mosin-Nagant rifle, DP-28 light machine gun and bunch of other "heavy" weapons. The winning players will generally wield at least one of the "blue" pr "green" weapons.
** Green: 5,56 ammo. It is mainly associated with the [=M416=] assault rifle and the [=FAMAS=] burst rifle (which both appear white in the hands of the players, for some reason.) However, heavy [=LMGs=] like M249 and [=QBB-97=] use this ammo as well.

* ConcussionFrags: The grenades here are notable for their long delay-fuse. Just throwing one at someone you sighted is useless: they'll manage to run away (or even charge at you, depending on their equipment and aggressiveness) long before it explodes. You generally have to cook them for about 3-4 seconds (not longer, or it may explode in your hand) ''and'' throw them at someone who hasn't sighted you yet to have a chance of scoring kills with these.

* GoodOldFisticuffs: The default "weapon" everyone starts with. While getting a weapon is obviously your first priority, fists also shouldn't be underestimated. In close quarters in particular, unarmed players can still kill others, especially if their opponent had a weak weapon like M9 or [=OTs-38=], a long-barelled one like DP-28 or Mosin-Nagant that was too cumbersome up close, or was simply stuck reloading their gun.

* HookHand: A hook can be found in pirate chests. It does less damage than bare fists, but attacks much faster. It's also the only melee weapon that auto-swings while the fire button is held down, which makes it by far the fastest at opening chests and crates of any kind.

** Even the shipping containers, whose thin metal walls are most definitely not bulletproof in RealLife can in fact ricochet bullets indefinitely. This a double-edged sword, as while hiding from bullets behind them is a good idea, getting ''inside'' one is not, as your opponent's bullets will then ricochet within the container itself, killing you very quickly if they have an automatic weapon of any kind.
** The oil barrels are unique, in that they'll ricochet the bullet, while still taking some damage from it, exploding after a dozen shots or so. Same goes for the stoves, and other exploding items made of metal.
* PyrrhicVictory: It's possible to kill your last opponent and then die immediately afterwards, whether because your shots hit each other at practically the same time, your enemy's grenade (or, humiliatingly, yours) exploded right after you killed the enemy player, or because you were both fighting in the Red Zone and it took off the last sliver of your health right after winning. The game will still count this as a victory, and a play its theme, but also note that there were 0 survivors.

* RandomlyGeneratedLoot: The locations of all the crates and other loot-bearing items, are fixed, down to every last crate, which are marked on the map (though you'll have no idea when approaching those marks on the map whether they haven't already been broken by other players). Their contents are not, with a few exceptions (i.e. guaranteed Deagle in the mansion's secret room, or a guaranteed Vector in the Hydra Bunker).

** Averted. [=OTs-38=] revolver is usually considered the second-worst pistol-type weapon in the game, and either the second- or third-worst weapon in the entire game (depending on one's opinion on the similarly controversial M1100). The few players who got good with M9 and its "shoot as fast as you pull the trigger" fire rate outright consider it the worst weapon.
** Played straight with the Peacemaker revolver, which has one of the highest [=DPS=] in the game. However, it is only available in the Desert mode/Potato mode, and is restricted to the rare .45 ammunition.

* ShortRangeShotgun: Zig-zagged, depending on the shotgun type. The first shotgun type, M870, has an effective range comparable to most pistols and MAC-10: the latter's projectiles still travel longer, but are reduced to stray shots when they get beyond its range. The twin-barreled [=MP220=] is similar in its range. M1100 plays this trope very straight, firing a literal cloud of low-damage flechettes up to four times in quick succession: hard to dodge up close, but is utterly useless at even medium ranges. Saiga-12, however, has both the firing rate and a good ranged accuracy. SPAS-12 is an outright inversion: it has a long barrel and a very tight spread, making it clumsy and easy to circle-strafe up close, but it is surprisingly effective at longer ranges. In the 50-50 mode, Red Leader is awarded a Super 90, which is an outright Sniper Shotgun.

----

* AllOrNothingReloads: Zig-zagged. Automatic weapons are reloaded in this manner, but all shotguns (besides dual-barrel [=MP220=]), and rifles like Mosin-Nagant are reloaded bullet-by-bullet, and can be fired halfway through the reload sequence.
* AmmunitionBackpack: Played straight. While players can still carry a decent amount of stuff just on their clothing somewhere [[note]]about 120 9mm ammo, 90 7.62 and 5.56 ammo and 15 12 gauge, alongside 5 bandages, a medkit, 2 sodas and adrenaline pills, in addition to two guns and up 3 grenades of all 3 kinds, for a total of 9[[/note]], getting a small backpack doubles what they can carry, and the normal and military backpacks also substantially increase your carrying capacity.
* AnAxeToGrind: Axes are the most common melee weapon around: you can find them stuck in the tree stumps, they'll ocasionally be present inside a sealed container in an underground bunker, and a bloodied axe may sometimes be mounted on a cabin's wall in place of a shotgun. It's very much possible to cut down someone unarmed or wielding a pistol/low-powered [=SMG=] indoors, but you are still better off with a weapon out in the open. Its greatest strength is in allowing you to open containers much faster, thus saving your precious seconds in this fast-paced game.

* AuthorityEqualsAsskicking: Played straight during the 50-50 mode, the players who become team leaders instantly get a very powerful gun (An-94 burst-fire machine gun for Blue leader, Super 90 long-range shotgun for Red one) with a ton of ammo and 8x scope to pick off enemies from long range, a Flare Gun to drop supplies for the allies, machetes for melee, tier 3 armor, helmet and backpack, and adrenaline permanently set to max. Lieutenants get tier 3 equipment along with 4x scopes, powerful [=M4A1=]-S weapon, and doubled magazine sizes for all their weapons.
* BladeOnAStick: As of the March 21, 2019 update, a Naginata can be found in the Teahouse, though it may sometimes be replaced with a katana. It is powerful, and has a great reach, but also swings slower than most other melee weapons.

* EmoteCommand: These replace chat as the means of player communication. While unregistered players are limited to smilies, thumbs-up and largely cosmetic emotes, those with accounts can request healing or a specific ammo type through the emote, and can also use the ping system to mark points of interest on the map.
* EverythingBreaks: Downplayed. Besides DieChairDie example, a range of other objects can also be destroyed, whether with weapons or just by your bare fists. Bushes may provide cover but only take a few bullets to get cut down, for instance; trees and stones will shrink in radius as they get attacked, before eventually getting destroyed. The thin wooden walls of shacks and outhouses can also be destroyed, along with the windows, doors, and internal walls of the proper houses. The greenhouse and teahouse can also be completely demolished. However, houses' retaining walls will never get damaged, and the houses are completely safe to be in if you are playing a 50-50 mode and there's an airstrike. (Though you should still stay away from doors and windows.) Bafflingly, same also applies to the shipping containers, as they'll simply ricochet all bullets away from them, and are equally unaffected by the explosions of any kind.

* FryingPanOfDoom: A very rare item found in airdrop crates. The frying pan has a longer range than other melee weapons, very strong damage, and can deflect bullets while on your back.

** Normal [=G18C=] is a decent short-ranged weapon, but is inferior to the MAC-10 and any of the shotguns. Dual-wielded [=G18Cs=] unleash an unrivalled storm of lead that's next to impossible to survive if you get hit by all of it. The downside is that they run dry in about a second, and then require 3 seconds of reloading. If you shot them at a wrong time, you are a sitting duck.

** Played straight with the Peacemaker revolver, which has one of the highest [=DPS=] in the game. However, it is only available in the Desert mode, and is restricted to the rare .45 ammunition.

* ShortRangeShotgun: Zig-zagged, depending on the shotgun type. The first shotgun type, M870, has an effective range comparable to most pistols and MAC-10: the latter's projectiles still travel longer, but are reduced to stray shots when they get beyond its range. The twin-barreled is similar [=MP220=]. M1100 plays this trope very straight, firing a literal cloud of low-damage flechettes up to four times in quick succession: hard to dodge up close, but is utterly useless at even medium ranges. Saiga-12, however, has both the firing rate and a good ranged accuracy. SPAS-12 is an outright inversion: it has a long barrel and a very tight spread, making it clumsy and easy to circle-strafe up close, but surprisingly effective at longer ranges. In the 50-50 mode, Red Leader is awarded a Super 90, which is an outright Sniper Shotgun.
* ShotgunsAreJustBetter: Although most shotguns in the game are {{short range|shotgun}}d, their sheer power up close makes them very useful. Most players will want to pack a shotgun for up-close situations.

* TemporaryOnlineContent: Various temporary modes pop up from time to time, such as Woods mode (map is densely covered in trees, only guns available are shotguns and light machine guns) and 50 vs. 50 (players are assigned to the Red or Blue team and fight to eliminate the other team). Certain weapons can only be found during these events.

* AdvancingWallOfDoom: The "Red Zone", which acts exactly as a wall that moves at a certain time intervals. The game's logo, which is a standard radiation symbol, and the red zone advancement clock, which uses the same symbol, all-but-confirms that it's actually radiation.
** However, it doesn't live up to much of the "doom" part at first. In fact, consuming pills, or multiple sodas, will initially allow you to regenerate health faster than it'll take it way. It gets more damaging as it expands, however, so that by the end of the round, such tactics will become unviable.

** When compared to the other melee options, axe swings slower than knives or a hook hand, but also has a better reach and so is usually a more practical weapon (even if the hook hand is unrivalled at opening crates). Katana and Naginata are both superior weapons due to their much greater reach, however, while the frying pan has its infamous defensive capability.

** Also subverted in that the players who get these perks are chosen randomly. While the already good players will certainly get a great benefit out of having these perks, weak players can still get themselves killed very easily. It's not uncommon to see either team's leader get few to no kills on the leaderboard; even the humiliating "0 damage dealt" is not unheard of.

*** Also, the pictograms that represent the weapons themselves when they are laying on the ground (which are different from their appearance in your hands) are always drawn in green, whereas the pictograms of all the other helpful objects (backpacks, armor, helmets, sodas, etc.) are drawn in white.

* EverythingBreaks: Downplayed. Besides DieChairDie example, a range of other objects can also be destroyed, whether with weapons or just by your bare fists. Bushes may provide cover but only take a few bullets to get cut down, for instance; trees and stones will shrink in radius as they get attacked, before eventually getting destroyed. The thin wooden walls of shacks and outhouses can also be destroyed, along with the windows, doors, and internal walls of the proper houses.
** However, houses' retaining walls will never get damaged, and the houses are completely safe to be in if you are playing a 50-50 mode and there's an airstrike. (Though you should still stay away from doors and windows.) Bafflingly, same also applies to the shipping containers, as they'll simply ricochet all bullets away from them, and are equally unaffected by the explosions of any kind.

** Inverted with the M9, which is the most common gun in the game, and thus is the weakest one. While expert players were still known to win with these (mainly through dual-wielding and learning to click extremely fast, since it shoots as fast as you pull the trigger), the player with just one of these is still severely outclassed by basically anyone else. In close quarters, even the completely unarmed players have good chances of winning against someone with an M9.

* LuckBasedMission: While sufficiently skilled players can win under nearly all conditions, luck is still very important. During one round, you may spawn right next to a mansion and be the first one to loot it and get a Deagle by the time the others appear. During the next round, you may end up in a field, open a nearby container, get a scope, and then get shot by another player who just found M870.
** That's not even accounting the luck inherent in the random loot. Some may open 5+ containers and find no weapons, or just get an M9. Others may immediately find AK-47 or [=MP220=], and then get 4x or 8x scope.
* MoreDakka: There are multiple guns that are devoted to fire rate above everything else, like the [=MAC=]-10 or [=G18C=]. There are also [=LMGs=] that fire relatively slowly, but have insane mag sizes, like [=DP=]-28 with 60 bullets or M249 with a full 100 bullets.

* PinballProjectile: Bullets will always ricochet from the frying pan, no matter how powerful they are. They'll also ricochet from any metal object: since all the underground bunkers have metal walls, this makes engagements there very dangerous. Players with [=SMGs=] may easily end up shooting so many bullets that they both kill their opponent(s) and get finished off by their own ricochet. The shipping docks are less cramped, and allow craftier players to set up complex ricochets to get those hiding behind impenetrable pallets.

* RegeneratingHealth: Health regeneration requires adrenaline, which is gained by using soda or pills.
** During the 50-50 matches, the two players lucky enough to be chosen as their respective team's leaders get no increased health, but their adrenaline is always at the maximum possible state, letting them move faster and regenerate health quickly.
* RevolversAreJustBetter: Averted. [=OTs-38=] revolver is usually considered the second-worst pistol-type weapon in the game, and either the second- or third-worst weapon in the entire game (depending on one's opinion on the similarly controversial M1100). The few players who got good with M9 and its "shoot as fast as you pull the trigger" fire rate outright consider it the worst weapon.

* ShortRangeShotgun: Zig-zagged, depending on the shotgun type. The first shotgun type, M870, has an effective range comparable to most pistols and MAC-10: the latter's projectiles still travel longer, but are reduced to stray shots when they get beyond its range. The twin-barreled is similar [=MP220=]. M1100 plays this trope very straight, firing a literal cloud of low-damage flechettes up to four times in quick succession: hard to dodge up close, but is utterly useless at even medium ranges. Saiga-12, however, has both the firing rate and a good ranged accuracy. SPAS-12 is an outright inversion: it has a long barrel and a very tight spread, making it clumsy and easy to circle-strafe up close, but surprisingly effective at longer ranges.
** In the 50-50 mode, Red Leader is awarded a Super 90, which is an outright Sniper Shotgun.
* SmokeOut: Smoke grenades are quite frequent, and completely obscure anything inside the smoke (as well as removing scope advantages to the players inside the smoke). A popular tactic is to first drop a smoke grenade into a house or another confined place, and then throw a regular one into the smoke, where no-one will notice it until it's too late.
** The same effect can also be obtained by destroying the fire extinguishers, which are present inside bunkers and in the police station.

* StoryBreadcrumbs: While nearly every other IoGame suffices with NoPlotNoProblem, the notes in this game's change log drop hints of a larger story, as do certain items and locations. For instance, there's a Hydra Bunker beneath the main island, which has several humans that look identical to the players being stored in tubes, while the change log that introduced it spoke of its role in developing SuperSerum. This fuels speculation that the entire island and the Battle Royale taking place there is a way to test out and refine super soldiers.
** Other bunkers contain [[https://survivio.fandom.com/wiki/Recorder audio]] [[https://survivio.fandom.com/wiki/Chrysanthemum_Bunker#Recordings logs]], which seem to reveal that the [=PARMA=] corporation in charge of the island was Japanese, and that they cooperated with the Russians, before the latter attacked to claim the island. It's also '''very''' strongly implied that a nuclear war [[AfterTheEnd has already taken place]] in the outside world.
* TemporaryOnlineContent: The 50-50 mode is only introduced as a temporary event, though it very popular during those days.

See also ''VideoGame/{{Foesio}}'' and ''VideoGame/ZombsRoyaleio'', for the other examples of battle royale .io games.

* FriendlyFireproof: Your teammates' shots and punches don't hurt you. However, grenades will.

In other words, it's a simplified and accelerated version of ''VideoGame/PlayerUnknownsBattlegrounds'' or ''VideoGame/{{Fortnite}}'' playable in your browser.

See also ''VideoGame/ZombsRoyaleio'', another battle royale IoGame.

* AnAxeToGrind: Axes are one of the stronger melee weapon types, but their real strength is their ability to destroy terrain objects faster than any other melee weapon. It's also the only way to open ammo crates. They are not common however, though similarly there are knives and samurai swords one can get.
* CombatResuscitation: In duo and squad mode, players who run out of health can only crawl around slowly until revived by a teammate.

** If a barrel is shot or struck a few times it will explode, causing death or serious injury to someone nearby.

* GunsAkimbo: Can be done with handguns, doubling your rate of fire and ammo capacity, but also your reload time.
* HookHand: A hook can be found in pirate chests. It does less damage than bare fists, but attacks much faster. It's also the only melee weapon that auto-swings while the fire button is held down.

** The AWM-S, only found very rarely in airdrops, is a sniper rifle that deals 180 damage per shot, making it a OneHitKill against targets that do not have good armor.

** Averted with the M9, which shoots rather slowly and poorly.

* ShortRangeShotgun: Played straight, with the exception of the SPAS-12, which has lower damage than other shotguns but boasts a tighter spread, making it more useful at longer ranges.
* SniperPistol: The [=DEagle=] 50 has perfect accuracy on its first shot, making it great from a distance.

* AnAxeToGrind: Axes are one of the stronger melee weapon types, but their real strength is their ability to destroy terrain objects faster than any other melee weapon. It's also the only way to open ammo crates.

* SniperPistol: The DEagle 50 has perfect accuracy on its first shot, making it great from a distance.

** The strongest melee weapon is the frying pan. Found rarely in airdrop crates, it is actually most useful when not equipped at all: if you keep it holstered, it acts as a shield for your back, something which no other melee weapon can do.

* ShortRangeShotgun: Played straight, with the exception of the SPAS-12, which has lower damage than other shotguns but boasts a tighter spread, making it more useful at longer ranges.

* FollowTheLeader: ''Surviv.io'' takes a lot of inspiration from ''VideoGame/PlayerUnknownsBattlegrounds''. The level 3 helmet is PUBG's iconic Spetsnaz helmet, the victory message is "Winner Winner Chicken Dinner!", and a frying pan item can be found, which can deflect attacks from the back.
