Bullet Train is a new demo game, developed by Epic Games, that allows you teleport yourself around a train station in virtual reality, all whilst fending of militia that are out to attack you. The device comes with special Touch controllers that give you 'hands' in your virtual world. You can point your hand towards the place that you want to go, squeeze your finger and you instantly teleport to your desired destination.
The biggest win here is that Bullet Train has shown that fast-paced action games can in fact work in the virtual reality environment, something that many people have been concerned about.
It's currently not clear whether Bullet Train will ever become a widely available game or if it will only remain as demo. Considering just how impressive and innovative it is however, don't bet against this game being commercially available at some time.
