Besides having dated graphics and poor controls this game suffers from the well known 'Release now patch later' bug. This game is full of bugs and is incredibly hard and bland. The spawning is rediculous and even when set on low makes the game unbearable.
There are tons of bugs, far too many to mention but so many that the game is just incomplete. It was rushed by its publisher and should have not come out this year. There is already a 1.1 patch out but this hardly fixes many of the issues plaguing users.
In all I'd say this game is about 30-40% complete. There are missing objects from buildings, absolutely no furniture, and hardly any monsters outside of the scripted areas. One could walk for half an hour and not see a single monster.
Avoid at all costs. This 'game' should be recalled and redone.
