Source-derived summary

Dota 2 is a 2013 multiplayer online battle arena (MOBA) video game by Valve. The game is a sequel to Defense of the Ancients (DotA), a community-created mod for Blizzard Entertainment's Warcraft III: Reign of Chaos. Dota 2 is played in matches between two teams of five players, with each team occupying and defending their own separate base on the map. Each of the ten players independently controls a character known as a hero that has unique abilities and differing styles of play. During a match, players collect experience points (XP) and items for their heroes to defeat the opposing team's heroes in player versus player (PvP) combat. A team wins by being the first to destroy the other team's Ancient, a large durable structure located in the center of each base.

Development of Dota 2 began in 2009 when IceFrog, lead designer of Defense of the Ancients, was hired by Valve to design a standalone remake in the Source game engine. It was released for Windows, OS X, and Linux via the digital distribution platform Steam in July 2013, following a Windows-only open beta phase that began two years prior. Dota 2 is fully free-to-play with no heroes or any other gameplay element needing to be bought or otherwise unlocked. Valve supports the game as a service, selling loot boxes and a battle pass subscription system called Dota Plus that offer non-gameplay altering virtual goods in return, such as hero cosmetics and audio replacement packs.

Editorial analysis

Why this record matters

The phrase “2013 video game” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.

Evidence profile

The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Sep 8, 2026. The linked authority identifier is Q771541. 2 of 2 selected statements include explicit references; 1 carry qualifiers and 0 use preferred rank. The first chronological checks are 2013 and 2009.

Critical limits

A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
