DotA-Allstars' roster of 100+ heroes is being brought over in its entirety. The single map games take place on is functionally identical to the one that you can download for free today in the Warcraft III mod. Items, skills, and upgrade paths are unchanged. Some hero skills work slightly better due to being freed from the now-ancient Warcraft III engine, but Dota 2 will be instantly familiar to any DotA player.
