Source SDK mod Estranged: Act I now on Steam for free

Omri Petitte at

It's always nice to see a mod progress from humble beginnings to its own Steam product page, and Estranged is fully deserving of the achievement. Alan Edwardes' spooky, puzzle-filled FPS plays and looks like a first-person Alan Wake, and it's an excellent deviation from standard run-and-gun zombie-fragging with its supernatural twists and an atmospheric sense of foreboding. The first act is available on Steam as a free download independent of any Source-based game, so you won't need Half-Life 2 to jump in and start exploring.
