YouTube user ProfessorGigaton has a pair of videos showing off his latest diabolical creation: a life-size model of Fallout 3's Railway Rifle. If you're inclined to take on the project yourself, one of the videos features a full tutorial to help you create your very own non-working replica. Lazy, like us? The supposed professor -- we're waiting on his school transcripts -- is also selling the model featured in the videos on eBay. The starting bid is $45, and it's sure to look great with your Fallout 3-inspired cosplay ... and will definitely come in handy in the post-apocalyptic world of 2012.
