To celebrate the 20th anniversary of the release of Quake 2 comes this singleplayer unit based on a side-mission to Stroggos!
This is the core source, with all the maps and associated .MAP-files along with custom textures and .BSPs!
IF you start it in Q2Pro, use "gamemap" instead of "map" and write this command first:
skill (your skill from 0 to 3)
skill 0 = Easy
skill 1 = Medium
skill 2 = Very Medium
skill 3 = Hard
