Mortal Kombat 8 to use Unreal 3 Engine

GI: How far into development is it?
Boon: The main thing we’re doing right now is the core technology. We’re using the Unreal 3 engine...

Here is the summary of the interview:
-Will use Unreal 3 Engine
-Gritty/dirty visual look (like Gears of War)
-Everything from the previous games is being throwed down
-No 3 fighting styles
-No colorful visuals
-More darker tone
-Different control scheme
-Completely different gameplay
-November 2008 release date (aiming to that date)
