Half-Life: Reamped

Years have passed since the Black Mesa incident. Since then, 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 it's demise. Absolute doom is inevitable, and all hope is lost. None of that matters, though, because you've been awoken from your slumber... and you're really pissed about it.
