Quake 2: Ground Zero
Expansion pack to Quake 2

Quake Mission Pack 2: Dissolution of Eternity
Even more things for Quake.

First person shooter action game with levels connected into a large world. Do quest and chat with the characters before you put a arrow into them. All the scientist in the evil organization try to make excuses but i leave no one alive. The level design feels a bit bad at times. It looks nice but the puzzles have a lack of logic to it.
