Modder Velocity Punch has revealed a debut trailer for Half-Life 2: Reamped, a DOOM-like mod for Half-Life 2. According to the modder, the story of Half-Life 2: Reamped unfolds in an alternate universe where, after the Black Mesa incident, "things have gone to hell."
"People are being killed by the millions by a force beyond our comprehension, the world is in absolute chaos, destruction washes over like a roaring sea of agony, and the human race is closing on its demise," the description of the mod reads.
