The good people at Did You Know Gaming have put together a new video all about the original Doom, that contains literally (not actually literally) 100 percent of everything there is to know about the classic shooter. Now's a good time for this, especially if you're going to QuakeCon next month and want to impress everyone there with all sorts of cool knowledge about the franchise's history after Doom 4 is (probably, maybe, hopefully?) officially revealed there. So enjoy this, while you have a break from absurd World Cup drama for the moment.
