Most of models, animations and scenario were extracted from Capcom’s Resident Evil games and I use it only for learning (#Fair_use) program the gameplay on UDK.
I own nothing here except the UnrealScript that I wrote. Everything else belongs to their respective owners.
UDK (Unreal Development Kit) is the free UE3 version from EpicGames, you can get it here, and start learning UnrealScript here,
