is a 2D Web Game shooter with a Three-Quarters View perspective, created by the Australian developer Sidney de Vries in 2016. The players pick one of the 10 classes with a different appearance, stats and loadout, and go fight each other in a variety of modes. It's possible to freely switch between the classes at every respawn, and logged-in players can alter their appearance further through a vast range of cosmetic items, which are randomly rewarded at the end of every match. Players with accounts can also apply to join clans, or create their own.Many of the classes in this game later reappeared in Karnage.io, and then in Krunker.io, the better-known browser FPS from the same creator.
Tropes present in Vertix.io:
- Action Bomb: The Duck is a downplayed version of this trope. While it doesn't explode, its attacks are nevertheless ultimately suicidal, since its jumps will always deal 100 damage to itself (out of 800 HP), allowing it to do a maximum of 8 jumps before dying (unless a medkit is picked up earlier on).
- And Your Reward Is Clothes: There's a huge amount of hats, shirts and weapon camos that be won by the victorious players at the end of the round.
- Bottomless Magazines: Played with. Each weapon does have a limited mag size, and exhausted magazines have to be replaced. However, those "spare" magazines (grenades for grenade launchers carried by several classes as secondaries, rockets for Rocketeers and even fuel for the Arsonist) are essentially infinite, allowing any player to fire and reload indefinitely.
- Child Prodigy: Run N' Gun, who's genius to a point where he can create a deadly weapon from a toy gun that can take out a Spray N Pray in 1 and a half clips (the toy gun can shoot 8 projectiles dealing 17 damage, and Spray N Pray has 200 HP. Do the math, 200 HP divided by 17 gives around roughly 11 or 12 shots.)
- Competence Zone: Run N' Gun is on the Kid side of the Competence Zone, however he seems pretty capable of handling himself while in combat and wields a toy gun he just so happened to turn into a weapon of war.
- Exploding Barrels: The barrels that have "OIL" written on them. However, their explosions are actually weaker than those of Rocketeer's rockets, or even grenade launchers carried by most classes, so they are hardly an "I win" button, or even a priority in combat.
- Everything Fades: Dead players disappear immediately. Explosion marks take a few seconds. Bullet marks on the walls stay for about 10 seconds or so.
- Friendly Fireproof: During the team modes, players are not hurt by any attacks from their team-mates. This even applies to the grenades and rockets, which still hurt those who launched them, but not any nearby team-mates.
- Inverted with the Nademan class. He is immune to his own Nades, and those from his allies, but not to those launched by the enemy Nademen, even though one would think they are identical.
- Gatling Good: Spray N Pray, who has a Minigun for his primary in this game and in Karnage.io.
- Glass Cannon: The Hunter only has 50 HP, when most other classes have 100 HP, Nademan 110, Rocketeer 120, Spray N Pray 200 and the Duck tops them all with 800 HP. This compensates for his ability to kill 100-HP classes with a single shot, and leave most others severely wounded.
- Ground Pound: This is the only attack of the ridiculously heavy Duck class, and it outright kills most characters up close. The downside is that it deals 100 damage to itself as well. Since it possesses 800 health, it can do a theoretical maximum of 8 jumps, (not counting medkits, which will restore 100 HP and thus essentially let you jump one more time). It is very risky class to play as, since it is also quite slow and the enemy players can keep shooting while running backwards. During the team modes, multiple enemies can also just split up and shoot at you from multiple directions.
- Hand Cannon: The Deagle used by the Detective. It kills a Hunter in a single shot, and most other classes in two.
- Hitbox Dissonance: Mhm. It's particularly obvious when someone is using the hunter.
- Joke Character: The Duck. It was originally added for the Duck Hunt mode, but that got cut because it was basically impossible for the Hunter to win. During the normal game, however, the Duck may get a few kills, but it is very difficult to excel as, since it'll always damage itself with its own attacks, and it is slower than the other classes, so if you fail to ambush a player around a corner, they can likely just retreat backwards while draining your health with continued shots.
- Kill It with Fire: The speciality of the Arsonist class.
- Mad Bomber: The Nademan class, whose only weapon is "Nade Launcher" that is essentially a semi-automatic grenade launcher with larger ammo capacity, but somewhat weaker grenades.
- Mighty Glacier: Spray N Pray class has the largest health and the greatest ammo capacity, but it is also slow, and deals the lowest damage per bullet. Duck is a really exaggerated example, as befits its Joke Character status.
- More Dakka: Downplayed for the Spray N Pray, as he has "only" 50 bullet capacity, which is much less than what he gained in the later games by Sidney. It also only twice the ammo capacity of the default Triggerman class, who moves faster and does more damage per bullet.
- Non-Fatal Explosions: Unless you are wounded (or a Hunter), the explosions from rockets and grenades will not instantly kill you if you are on the outer edge of their blast radius. Oil Barrel explosions are only immediately lethal to Hunters. Rocketeers, Ducks and Spray N Pray classes can survive being at the epicenter of any in-game explosion.
- No Plot? No Problem!: Much like in every other .io Game.
- One-Hit Kill: A direct hit from a Grenade Launcher kills every class but Rocketeer and Spray N Pray. A single shot from the Hunter's Sniper Rifle does this to every class bar the Rocketer, Nademan and the Duck.
- Hunter himself, however, is insta-killed not just by the above, but also by a single shot from the Detective's Deagle, or by a Nade (which are otherwise weaker than the normal grenades.)
- One-Hit Polykill: Hunter's sniper rifle can kill two or more players at once.
- Rocket-Tag Gameplay: The gamemode that makes everyone a hunter a default.
- Short-Range Shotgun: Averted; the shotgun's spread is a narrow cone, whose range is not meaningfully shorter than that of the other gun-wielding classes.
- Slow Laser: The Toy Blaster weapon used by the Run N Gun either fires these, or normal bullets (since their appearance is the same): it's never clarified.
- Spread Shot: Vince's shotgun fires a spread of 4 pellets. The Boss in the Boss Hunt mode fires 3 shots as his long-ranged attack.
- Stone Wall: Subverted with the duck, because its only attack does damage to itself. Played Straight with Spray N Pray.
- Tagalong Kid: Run N' Gun. See Child Prodigy and Competence Zone section.
- Video Game Flamethrowers Suck: Downplayed for the Arsonist class. Sure, his flamethrower is still much shorter-ranged than any of the real-life ones...but all of the maps are mazes of narrow corridors and sharp corners, so his range really matters. Up close, he's one of the most powerful classes.
