A group of Half-Life fans were so enamored of Valve's classic first-person shooter that they produced a fan film based on the scifi game's mythology. As always, a crowbar is an essential tool for staying alive.

Here's the $1,200 project's synopsis from the filmmakers:

Inspired by the Half-Life Video Game series, this is an action packed short film centering around Adrian Shephard and a band of resistance fighters struggling to get out a warning about the impending invasion.
