Fan-made Half-Life Opposing Force sequel released
In Prospekt, you pick up the story of US Marine Adrian Shephard after he was teleported into the Nova Prospekt prison by the Vortigaunt to help fight the Combine. The mod was recently given the seal of approval from Valve and the developer estimates that it's about as long as Half-Life 2: Episode One.
The trailer sets the foundation for Prospekt's story, gives you a tour of the game's environments, and shows you some of the enemies you'll face off against. We've missed that distinctive sound of the shotgun!
