Dota 2 Update - December 12th, 2013

Hmmmm....... Today (or yesterday) updates is kinda huge for me because the update size is about 500MB.
But, the update is worth for it. Because there is a new hero, new matchmaking, and NEW GAME MODE.
The update conclude only three of it ( I think so) :

• Added Wraith Night (Game Mode, till 31 December I think)
• Added Ranked Matchmaking
• Added Legion Commander (The hero is female)

And that's all for 12th December updates. Hope this is useful :) GL!
