Not intimately familiar with CrimeCraft?
If you take a tactical shooter, RPG, MMO and modern day war-torn setting and pop 'em all into the Unreal 3 Engine you'd probably end up with CrimeCraft. Check your guns at the door as Vogster Entertainment's Casey Dickinson and Matt McEnerney walk us through their ubran, persistent-online action game, CrimeCraft... and all the gritty exploration and PVP combat you'll encounter on the PC.
This genre hybrid is currently is in closed beta with a larger beta expected to be announced "probably next month."
