Half-Life 2: Episode 2 Mod - Aberration Part 1
When the Combine invaded, Gera was one of the first cities to be taken over. You were one of the few Resistance fighters in this small city, located North of White Forest, trying to take it back. You were captured.
Aberration Part 1 is finally released! Requires HL2 EP 2 to play, extract to your steam/steamapps/sourcemods folder, then restart steam. Thanks to NH2 and Hen for an idea.
