Yes! A new Valve game. And while we currently have no idea what that game might be, we also kinda do. We know that Valve hired Defense of the Ancients Allstars developer IceFrog, which almost certainly means they’re developing something in a top down, small-unit-tactics multiplayer vein. Oh, and Valve also filed the trademark for DotA, and there was a tweet from a voice actor saying he had fun at Valve “recording for DotA”, but that’s since been removed.

The rumors and speculation can cease. Valve is making Dota 2, we've played it, and it's already amazing even though it's not coming out until next year. And we haven't yet laid eyes on Dota 2's biggest innovation: a radical approach to integrating the game's community back into the gameplay itself.

What's a Dota?

Dota 2 takes its name from the Warcraft III mod Defense of the Ancients, a drastic change to that stock real-time strategy title, which pits two teams of five players against each other in highly competitive, 40-minute or longer matches. Unlike most RTSes, DotA has each player controlling a single hero who levels up and stockpiles gold to purchase powerful equipment and consumables. As computer-controlled armies continually spawn and rush the enemy's base, players are responsible for using their powerful heroes to turn the tide of the battle in their favor.

DotA quickly gained massive popularity on Blizzard's Battle.net service, with the growing community utilizing user-created channels and the rudimentary custom game browser to connect players. As mods tend to do, it branched into several variations as time passed. Eventually, one rose to the top: DotA-Allstars, originally created by Steve "Guinsoo" Feak (now employed with Riot Games designing League of Legends). Allstars is currently maintained and updated by IceFrog (who declined to give his real name), who was hired by Valve in 2009 and is now working on Dota 2.
