A group of independent filmmakers posted this trailer for Beyond Back Mesa, a two-year production inspired by Valve's Half-Life series. The short action film centers around "Adrian Shephard and a band of resistance fighters struggling to get out a warning about the impending invasion."

Even with only a $1,200 budget to pay for equipment, costumes/props, and music, the crew managed to put together an impressive movie, at least judging by this teaser, that sports some neat shoot-outs and special effects.

There's no word yet on when the general public will be able to watch Beyond Back Mesa in its entirety, but the movie is currently being showed at film festivals. You can follow news for the short film at its Facebook page.
