It was a kinda janky 3D Action Adventure from around 2000. Back then it had really beautiful and colorful graphics. I remember playing it on my first "real" PC and being amazed by how it looked.
It also stands out to me for being actually funny and comitting to being a comedy game.
I loved this game! The humour was my favourite part - very dry and very British. A fun shooter with a lot of variety. Amazing soundtrack by Jeremy Soule. I found the game very difficult, though - I doubt I ever got close to finishing it. How about you?
