Credits to a thread on NeoGAF, two in-game screenshots have been released to the interwebs thanks to a leak from a chinese site that reportedly got hold of some DotA 2 footage.
The two screenshots give you the first look at the interface and everything you would want to know about the game. Heroes such as Shadowfiend and Doom Bringer can be seen in the images too.
DotA 2 is will be publicly previewed for the first time at gamescom that is to kick off on August 17, 2011. Stay tuned!
