A recent patch has added three new heroes to the DotA 2 roster: Skeleton King, Broodmother and Queen of Pain. All three characters are available right away in general matchmaking, so go try them out!
A new feature has also been added to DotA 2, a pause function. Players will now be able to pause the game when needed (up to three times per match, per player). Valve will be keeping an eye on the system and will decide if they need to change the ruleset.
