"From the studio that brought us Half-Life, Portal and Team Fortress, the next big thing will be Dota 2. That's a new Defense of the Ancients game coming to PC and Mac in 2011.
Valve describes the game as "a massive sequel for one of the most played games in the world."
GameInformer.com spilled the first official details, saying that the game runs on Valve's Source engine and includes voice chat. Gameplay appears to be faithful to the series' roots, supporting three-lane maps and focusing on multiplayer competition (with artificial intelligence taking over for players whose connections drop.) Graphics are upgraded, though said to follow in the original cartoony style birthed in the original. Steamworks-based achievements will be able to reward players for actions in the player community as well as in the game."
