Double Action is about diving, flipping, and sliding your way into 90’s action movie-inspired multiplayer mayhem. The game is completely free (no hats!), runs on Valve’s Source engine, and has been in development for about 2 years.
If you already have version Epsilon installed then you can unzip this file over top of Epsilon to install Zeta. DO NOT install this one if you don't have Epsilon already installed and DO NOT try to install it over a different version.
