Valve wants to bring Dota 2 to tablets. Company boss Gabe Newell told Kotaku that a tablet version of the free-to-play multiplayer online battle arena game is one of the “interesting projects” that the company is currently working on, though initial tests have left much to be desired.

“We were working on getting Dota 2 running on some tablets,” Newell said. “That ended up being kind of a disappointment. But the good news is that tablets are getting faster very quickly, so I think we’ll get the kind of performance we want and other game developers want in the near future.”

Dota 2 is scheduled for release on PC and Mac. The game combines action and real-time strategy elements in multiplayer matches that pit teams of player-controlled heroes against one another. The game will include integrated voice chat and computer-controlled characters that will take over for players who disconnect during play sessions, as well as a coaching system, where veteran players will have the chance to tutor newcomers.
