TUG

"TUG" is a horror shooter game that can be played as a single-player, co-op with 2 players, or multi-player. The game features masterful visuals but has been reported as buggy. The developers are working on a new engine for version 2.0, which promises enhanced graphics, flexible modding and distribution systems, and new terrain generation. Existing users will have early access to the new version and will be able to invite friends.
