​This was actually a quick and fun project that I've participated a while back at Polycount.com. The whole project took about 2 weeks or so to finish. The idea was to create a real-time game environment base on the theme concept art of Dues EX and you have about a month to finish. 

Originally,  all of the assets was integrated into Unreal Engine 3 but I had so much fun that I decided to port everything to CryEngine 3.
