Okay lets add here all the Video Game fan films you can found.
I found this from Kotaku Fallout: Nuka Break
"Join Twig (Zack Finfrock), a former Vault 10 Dweller, as he searches the barren wasteland of eastern California for ice-cold Nuka Cola.
Along for the ride is Ben (Aaron Giles), a radiation-ravaged ghoul, and Scarlett (Tybee Diskin), a sexy former slave.
Together, the three attempt to survive both the harsh wastes and a relentless group of bounty hunters while trying to find the coveted beverage -- Nuka Cola
Haha this was really good. Guns, props and Ghoul make-up looks good and the humor works EDIT:Beyond Black Mesa
"Short Independent fan film 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.
Meh :/ Looks okay but the characters looks too clean, Combine troopers are worst shots than stormtroopers and no headcraps (probally because they run out of money?)
Another HL2 Fan film:Escape From City 17 - Part One - New Cut
"Filmed guerilla style. No crew. First two episodes made on a $500 budget, not including previous capital. Valve flew the brothers out to Seattle last year before it the release, and mentioned they were 'blown away' by the project on Steam.
Can't wait for part 2
