Have you ever wanted to sneak around the Quake universe, pick the right moment to bypass the guards or escape an angry mob trying to find you?
Truly great work, things like this shouldn't be possible in the Quake engine, but the author has made them work anyway. The architecture is gorgeous, and the gameplay is both easy to grasp yet offers huge depth. For any Quake fan, or fan of stealth games this is a must-have!
