I haven't checked recently, but the internet has to be completely full of videos focusing on the Battlefield 4 beta by now. Surely. This one, however, is quite original. It reframes the game as a 16-bit shooter (although I think it looks a lot more like a 32-Bit game on the Amiga CD32 or something) and it looks pretty cool.
Then of course it all devolves into the regular Battlefield cool explodey moments you'd expect to see in a video like this, but that's okay, because that is also interesting to watch!
Thanks Chris T!
