A couple of levels, and a small shapes patch. The first level is seriously claustrophobic, and you'll be hitting your head on the stairs every time you go down. The fun part comes in with the small shapes patch...
A reproduction of a science campus in Belgium. Amazingly realistic... the enclosed shapes are great. You won't have too much time to look at 'em, though...
Two rooms with different ways of killing bobs. It is pretty amusing to watch them waste themselves... amazing what you can make 'em do. Nice construction, as well.
