Now that you’ve gotten your fill of Bethesda’s post-apocalyptic Fallout 3, why not take the action out of the living room and into your local park. Wander the playground with this homemade steampunk raygun. It shoots radiation shots of some sort and may or may not give you throat cancer. If you want to make your own, it’ll take awhile due to the lack of instructions but with a little handiwork, you’ll be gunning down aliens in no time. Space aliens, that is.
