Action Quake2 is a DM mod designed along the lines of a good action movie. No BFGs or rapid fire rocket launchers here, and not a plasma weapon or laser gun in sight. What we DO have is a mod where stealth and strategy pay off more than the ability to shoot yourself in the feet with a BFG.
AQ2 was developed to recreate the look and feel of an action movie, having a fast pace and a semi-realistic damage system. It features many maps recreating realistic settings, such as city streets and office buildings, with a balanced range of weapons and equipment inspired by action movies.
