This and the version from gamemaps and l4d2maps websites are the same. So keep downloading and enjoy this great map. This map has had no update for 2 years, so we updated it. We have made this one English friendly. Portal: English, SGC: English. Carter, Teal'c, O'Neill, Gen. Hammond: English etc etc. Will it make any sense? Well, Dr. Seuss thinks so! Not compatible with any other version. Enjoy everyone!
Download. Unpack with 7zip or WinRAR. Install to your Left 4 Dead 2 addons directory: C:\Program Files (x86)\Steam\steamapps\common\Left 4 Dead 2\left4dead2\addons. Then let the Stargate/Portal/L4D2 adventure in apocalyptic hunting begin!
