Valve's stand-alone sequel to the popular Warcraft III mod Defense Of The Ancients. Valve had hired Icefrog (One of the game's original developers) and have been working on a commercial sequel/remake of a sort called Dota 2. It was recreated on the Source engine with all-new graphics and UI. It was released in July 2013 after a lengthy closed beta. Recent updates about Dota 2 can be seen here.
Dota 2 provides examples of the following tropes:
Aerith and Bob: Most heroes have fancy names that you will never see in real life, except for Sven, Magnus, Chen and Invoker (whose 'true name of power' is Carl).
Ascended Glitch: Several quirks of the Warcraft III engine were intentionally replicated, and several quirks of the early beta have been left intact as well:
Though integral to the game for years, "denying" allied creeps (killing them to deny the enemy the cash and experience reward) was originally an unintended feature.
Creep stacking is a method where a player draws the aggression of neutral creeps to make another stack of them spawn in the same camp at the minute mark, when all empty camps will respawn. Though originally a glitch, this is such an integral part of DotA that removing it was unthinkable.
Although since removed, Valve at one point stated that the technique known as "fountain hooking" would be left in the game. Fountain hooking refers to aggressively teleporting or dragging an enemy into their opponent's fountain, where the high damage will likely assure an Instant Kill. While it's most well known with Pudge and Chen, it was possible with a small handful of other heroes as well.
The original DotA mod had two factions of heroes to choose from, including a neutral side, and normally defaults to allowing the Sentinel (Radiant) and Scourge (Dire) to only pick from their hero pools and the neutrals. Completely open picking became ubiquitous in later versions, however, so the formerly neutral pool has been integrated into the Sentinel and Scourge sides. Thus there are True Neutral characters like Sand King on the Dire, and mercenaries like Bounty Hunter on the Radiant.
Backstories of various characters have been changed, in order to avoid references to Frozen Throne, since Dota 2 is set in a separate universe, and Blizzard owns the copyrights to all elements of the Warcraft games, many of which were incorporated into the original DotA. However, even characters whose backstories have been radically changed are still on whichever side they were on in DotA. So, while Centaur Warchief is a heroic saviour fighting for the Sentinel in DotA, his equivalent, Centaur Warrunner, is simply a Blood Knight on the side of the Radiant in Dota 2.
Baleful Polymorph: Lion, Rhasta and the item Scythe of Vyse can turn an enemy hero into frogs, chickens and pigs, respectively.
Beauty Equals Goodness: The more humanoid, attractive females are all on the side of Radiant. Dire gets the more non-humanoid ones, ambiguous-looking (Mortred) or Evil Is Sexy ones (Akasha). Though the Radiant itself isn't 100% Good mostly and also has its share of non-humanoid ones (eg: Slithice).
Call a Smeerp a "Rabbit": Quite a few characters, mostly with Sniper and the archers; Sniper refers to arrows as "feather bullets" and Windranger refers to Sniper's bullets in turn as "tiny featherless arrows"
Captain Ersatz: Due to certain heroes from the original mod being named directly after Blizzard-trademarked characters or races, some heroes had to be renamed.
Cast of Snowflakes: Every character has unique appearances, abilities, backstories, and extensive responses to certain events. All of them are fill in very different niches in gameplay and team composition, to the point where several heroes' schtick cannot be replicated by another.
Combat Pragmatist: Split-pushing, or "Rat Dota", involves forcing the enemy team to one location on the map, and then going to the opposite end to destroy their towers and barracks unchallenged. Many heroes (particularly Pushers) such as Nature's Prophet and Broodmother are notable for this.
Magnus can potentially suck the entire enemy team into a single compact area in front of him and disable all of them with Reverse Polarity before Sven walks up and uses his high damage and Cleave to dice them all up in seconds while using Storm Hammer a smaller area-of-effect stun to give them more time to beat on their victims and Magnus' Empower gives both of them more damage and Cleave.
Ursa has effectively nigh-infinite potential damage due to being able to do more damage every attack using Fury Swipes, and almost always succesfully uses this to kill Roshan at an early stage of the game. However, he will usually not last long enough without lifesteal effects which, other than for the somewhat expensive Vladmir's Offering, do not work with Fury Swipes. Enter Wraith King and his Vampiric Aura which grants all nearby Allies Lifesteal.
Huskar has an ability that deals 50% (or 65% with an Aghanim's) of the opponent's current health in damage, and Necrophos has an ability that can deal damage to a target based on how much health it is missing (up to around 1-1 damage for each point of health missing). Targets of this combination tend to die.
Tiny's ultimate makes him bigger and stronger for each level put into it, but with the tradeoff that each one reduces his attack speed permanently. Enter Wisp and its Overcharge ability that gives Tiny just enough attack speed to effectively ignore the attack speed loss.
Complete Immortality: Four characters (Keeper of the Light, Enigma, Chaos Knight, and Wisp) are "Fundamentals": beings from the beginning of reality that are ageless and impossible to truly kill. The Radiant and the Dire are also Fundamentals, ones that were cast out by the others for constantly feuding.
Continuity Reboot: The original DotA never had much of a story past minor hero and items descriptions, and for the most of it used lore already established in Warcraft as a base. With the remake being developed by Valve, they couldn't obviously use anything relating to Blizzard products. This gave them the chance to completely clean the slate and create their own fantasy world, giving all the heroes completely new and original backstories, though still using the original DotA heroes as a base.
Crutch Character: Towers can be seen as this: they are powerful early game when heroes are weak, but since they do not scale at all and cannot heal damage taken,
Death of a Thousand Cuts: Many heroes have area-of-effect spells that don't do very much damage to single targets at all, or have auras that don't do a lot by themselves. The difference comes when you stack those spells and auras with those of the other four players on your team, which can quickly grind down even the hardest carries in the game under the right situation. That makes tactics very important to players.
Death Ray: The Dagon's active ability Energy Burst, which fires a beam that deals instant magical damage to the target.
Dem Bones: The Dire has quite a few undead heroes.
The Dev Team Thinks of Everything: Valve had every voice actor do a line for purchasing an Aghanim's Scepter, even heroes whose ulti couldn't be upgraded. Loads of heroes have had ultimate upgrades added since the lines were recorded.
Everyone Calls Him Barkeep: The game calls most heroes by their titles instead of their proper names. This spreads to the player base as well.
Evil Laugh: Very prominent. Almost every hero has a response of this sort to killing an enemy hero. Oddly, in this game it doesn't produce any Narm feelings, because whoever just scored a kill will usually feel like a badass, so if you get the laugh response it just makes the experience better.
All but one of Tidehunter's "Killing a Rival" responses (and then some) are about Kunkka, and Tide will say any of them quite often even if Kunkka is not in the same game.
Gameplay and Story Segregation: Heroes can range wildly from mere Badass Normals with little supernatural abilities (Axe and Juggernaut) to ancient and powerful sorcerers (Invoker, Lich, Rubick,...) to even Physical Gods (Elder Titan, Ancient Apparition, the four Fundamentals,...). However, in-game their power levels are all roughly the same.
Gender Flip: Tresdin the Legion Commander. In DotA he was a male, horse-riding, mustachioed, racist to non-humans, commander of a legion. In Dota 2 he has become a woman with somewhat darker skin who fights on foot. The racism is toned down, but she is still somewhat aggressive towards non-humans, especially demons after Stonehall.
Additionally, Auroth the Winter Wyvern has also been confirmed for a gender flip as she shares the same voice actor as Tresdin.
Genre Shift: The various holiday events all deviate from the standard 5v5 Ancient-destroying gameplay.
Both the 2012 and 2013 Diretide events are Capture the Flag competitions that segues into a 10-on-1 fight against a buffed Roshan.
The 2012 Greeviling event was a race between both teams to kill as many Greevils as possible in a set time limit.
The 2013 Wraith Night event was a 5-man Tower Defense game where five heroes defeat waves of monsters and heroes for 13 rounds.
The 2014 New Bloom event pit the team against Year Beast. Slay it and you can get loots for cosmetic item crafting. The most damaging players got a VERY rare Jadehoof courier.
There are too many Incredibly Lame ones to count (although, impressively, it almost never diminishes the overall experience):
Lich (casting Frost Armor): What's a little frost among friends?
Faceless Void: In the land of time, the no-eyed man is king.
Chaos Knight: Armageddon out of here.
Outworld Devourer: Good news travels slowly. Bad news has wings.
The blog update for Bristleback says:
Better watch your back, because Bristleback is back! (kill me).
Homing Boulders: It's possible for autoattacks and spells to change direction in midair and fly across the map if the targeted hero teleports away or moves away very quickly. This is especially ridiculous with some characters, like Sniper, whose bullets can spin right around in midair to chase their target, or Tiny, whose Toss throws a nearby unit to a target enemy, even if the Toss trajectory makes no sense and bends around in the air. It also gets absolutely ridiculous with skills such as Huskar's Life Breaknote he leaps at an enemy for massive damage, where Huskar actually changes direction mid-air if his target blinks away, even if the target blinks behind Huskar.
Instant 180 Degree Turn: Averted. "Turn time", or the half-second pause that a hero takes to turn to another direction of running, is an important gameplay mechanic to get used to and one of the balancing factors for melee vs. ranged heroes to ensure that the latter can't just kite the former with complete impunity.
I Shall Taunt You: Certain characters have specific, mocking lines when killing other heroes. Some even have dedicated taunt animations that can be executed on command if you own the item in your backpack. Axe even has an ability for this too, to get units to attack him so he can take advantage of his other ability, Counter Helix.
Since the damage output for casters comes mostly from their burst-damage nukes, they tend to be powerful early game when enemy heroes have few items; but because nuke damage generally do not scale with items they fall short later when enemies become able to shrug their nukes (and their weak auto-attacks) off.
Compare to physical damage dealers, who rely on right-click auto-attacks enhanced with passive abilities: their damage early on is weak, but becomes stronger and stronger as they acquire more and more items, and in the late game they become major nexuses of power.
Magikarp Power: Hard carries like Medusa or Anti-Mage start the game very weak and vulnerable to ganks but can become unstoppable, able to 1v5 whole teams by themselves if properly farmed by late game.
More than Mind Control: Non-heroes exposed to Direstone or Radiant ore quickly become warped by it and turned into creeps. This is ultimately reversible, though not without extreme effort.
Monster Allies: Chen and Enchantress can turn neutral creeps into their loyal followers. The Helm of the Dominator extends this capability to everyone with its active Dominate.
Ms. Fanservice: On whole, averted. While some humanoid heroines ARE attractive, they're not overly sexualized to the point of fanservice.
Mythology Gag: If you look closely at the icon for item recipes, the icon in the middle is the symbol of the Combine from Half-Life 2.
Stealth Pun: ...Because you use recipes to COMBINE items.
No Experience Points for Medic: You only get assist credit if you damage the slain enemy. This is why certain supports (like Omniknight) tend to not have great scores since they lack easy damage spells to pick assists up.
However, simply being near a dying enemy nets you gold and experience.
Non-Action Guy: The two Ancients (the Radiant and the Dire) manifest as defenceless buildings that must rely on towers and heroes to protect.
Noodle Incident: The vast majority of the hero's backstories/bios are chock full of them. Almost all of them are vague at best.
No Sell: One of the biggest mechanics of the game's meta-strategy is that some heroes are complete hard counters to others (such as Omniknight's Repel being able to completely nullify the effects of Slardar's Amplify Damage and many of Spirit Breaker's abilities, but Repel itself able to be purged by a Diffusal Blade), so choosing the correct lineup or item build against the other team can result in this. Again, rewarding good decision makings: turn the tide of the battles even when you are behind, if you are smarter than your foes.
Our Dwarves Are Different: While not outright stated, the Keen (Sniper, Tinker, Clockwerk, Gryocopter, and the smaller half of Alchemist) share similarities with Dwarves. Most are incredibly smart and sport facial hair, and all are very small in stature.
Perfect Play AI: When playing with/against bots, they will most often perform perfect chain stuns/disables, on the level of pro players.
Race Against the Clock: If both teams go all-in on a push into the enemy base, it usually turns into this. Known as a "base race" in the community.
Revenue Enhancing Devices: Despite the fact that the game is completely play-for-free from the get-go, and you play as every hero from the start, the online store still manages to have a ridiculous amount of purchasable-with-real-money content. With the exception of tournament tickets (which allow you to spectate international tournaments from in-game) though, all of these store items are only cosmetic in nature, a vast number of them can be obtained through Random Drop as above (with even some only being available through drop and not through the store), and none of the availability of the game itself is locked away. An exception to the tournament ticket rule goes to the annual "The International" tournament held by Valve. You can watch the in-game matches for free, and Valve makes money by selling "See it live" tickets and (for the 2013 tourney) the Compendium which is $10 for at least $35 worth of content and a promise for more as more Compendiums are bought.
Frostivus 2013 Day 2: BY DECREE OF THE ONLY KING THAT MATTERS - FROSTIVUS IS CANCELLED
Schizo Tech: Several of the Keen (ie, the Gnome analogues) have incredibly advanced technology, Tinker even having lasers, rockets, and automonous robots. They exist alongside and are routinely beaten by people using arrows and swords. However, Gryocopter's backstory mentions finding an "incomplete schematic for a Gyrocopter, the world’s first manned, non-magical flying device". So, while technology, with the help of magic, is incredibly advanced, pure technology is mostly inept.
Shout-Out: Just as with the original, with the sheer number of assets in the game, most anything is a reference to something else:
A red headed spellcaster named 'Lina the Slayer' with the skill Dragon Slave, and an ultimate named Laguna Blade?
The items Sange and Yasha, Black King Bar, and Monkey King Bar are all from the Phantasy Star series.
The Monkey King Bar also refers to the weapon of Sun Wukong from Journey to the West, both in its name, and its inability to miss.
Bounty Hunter bears some resemblance to an older group of [[Tabletop Games/Warhammer rat-man ninjas with shuriken]], and Chaos Knight's backstory, colour scheme, armour, and steed appear to draw on some [[Tabletop Games/Warhammer other Chaos Knights]]. Gyrocopter and Sniper draw on the aesthetic of [[Tabletop Games/Warhammer a certain other group of]] Schizo Tech-wielding dwarves, as well.
Beating the newly resurrected Wraith King shows the words YOU DEFEATED.
Skill Gate Characters: Quite a few heroes are inherently imbalanced in the lower brackets where people tend to pick carries instead of disablers or supports, and things like warding, anti-invisibility and team coordination are largely non-existent, but because of their Weaksauce Weaknesses they are pretty much ignored in organised games.
Socketed Equipment: As of November 2013, cosmetic items now can be socketed, for gems which give special cosmetic effects.
Standard Status Effects: Poison damage, paralysis, stuns, slows, and silences are invaluable in teamfights. Several heroes (Venomancer, Viper, Silencer, Bane, Lich, and Spirit Breaker, to name a few) are themed entirely around a specific status effect.
The Diffusal Blade's active ability and the neutral Satyr Banisher's ability both named Purge, which purge most negative buffs from allies and positive buffs from enemies in addition to slowing them.
Shadow Demon's Demonic Purge is a variation of the above, being useable only on enemies but also deals damage and able to remove certain buffs that the normal Purge can't.
Suffers Newbies Poorly: As with many other games in the MOBA genre, gameplay is extremely serious business, and new players are often subjected to an incredible amount of vitriol. The developers have tried to alleviate some of this by introducing a tutorial mode, but it's a long and steep learning curve no matter how the game is played.
Summon Magic: Certain heroes have the ability to summon minions that range from expendable (Broodmother's spiderlings) to very valuable (Visage's familiars). The Necronomicon allows all heroes to do this with its active ability Demonic Summoning.
Talking Is a Free Action: Characters regularly banter with each other. Heroes will comment on loads of events, including buying a specific item, calling misses, killing certain other heroes, meeting certain allied heroes, getting a cosmetic item at the end of a game, and getting banned during the ban/pick process in Captain's Mode. Taken to ludicrous extremes with Storm Spirit, who takes this up to Lull Destruction.
Talking to Himself: Despite having well over a hundred different heroes, there are scarcely more than ten or twenty voice actors to give them all voices. While some of these are fairly obvious (Anti-Mage, Beastmaster, Necrophos and Warlock are all voiced by Sam A. Mowry, and sound like the same person at different ages), quite a few are very surprising (Crystal Maiden, Drow Ranger, Enchantress, Mirana, Phantom Assassin, Spectre, and Vengeful Spirit are all voiced by Gin Hammond, and Timbersaw, Bristleback, Skywrath Mage, and Abaddon are all voiced by TJ Ramini).
This can reach its peak when certain Heroes give responses after killing others.
Up to Eleven: It is now possible, with the addition of Earth Spirit, to play a match where all 10 heroes are voiced by Nolan North.
Touched by Vorlons: Several characters have abilities conferred by beings greater than themselves.
Unexplained Accent: A good majority of the heroes are outfitted with various accents despite not being in the real world.
Anti-Mage, Invoker, and seemingly Axe speak with light English accents. Pudge speaks with a more thick urban English accent, as does Bristleback.
Mirana speaks with a light Greek accent.
Meepo's accent sounds somewhat like a typical Brooklyn accent.
Luna has a very thick Irish accent.
Death Prophet has a very thick French accent, while Phantom Assassin has a more subtle one, perhaps French-Canadian.
Slark has what sounds like an Australian accent.
Through her echoing voice, Medusa sounds like she has a high class English accent, or an older American accent, like one from the 1940's -1950's.
Chaos Knight has a deep voice, but he appears to have a German accent.
Dazzle has a Mali accent.
Magnus has an Ethiopian accent.
Witch Doctor has a Rastafarian-type accent.
Bloodseeker sounds like he has a Central American Accent to go with his 'Sacrificial Tribal' Theme.
Shadow Shaman has a Persian accent.
Sven and Tusk have Swedish accents. Sven sounds more like your typical Viking where Tusk sounds more like a Modern Swedish Accent.
Brewmaster and Juggernaut have Japanese accents.
Lone Druid has a Scottish accent.
Skywrath Mage, Vengeful Spirit, and Lycan seems to speak with stereotypical eastern European-sounding accents.
Updated Re-release: The game is more or less a direct clone of the original Defense Of The Ancients All Stars map from Warcraft III, but has a new engine, brand new graphics and a modern interface. Several characters work differently because of the new engine, as the old Warcraft III engine put restrictions on certain spells. Rubick can steal transformation skills (most notably Elder Dragon Form and Shapeshift), and Luna's Moon Glaives work differently.
What the Hell, Player?: Attempt repeatedly to use an ability when it's on cooldown or you don't have enough mana, and your hero will sound more and more agitated/annoyed with your rapid clicking. Troll Warlord especially hates it when you do that.
A Wizard Did It: The accepted canon behind any bugs encountered within the game is that a particularly shitty wizard is mucking around with the battlefield.
World of Ham: Every hero, even the most subdued (but not The Speechless), will mock enemies they kill and laugh when they score multi-kills. Also, many heroes will utter a hammy line when using a skill.
