Bullet Train is what happens when Oculus hooks up with Epic Games to see what a state of the art AAA type VR experience might look like. It's basically an experiment of sorts, to see how far graphics can be pushed using the Unreal Engine 4 and the first version of the Oculus consumer hardware. From this standpoint, it does a wonderful job of giving us a glimpse of higher-end VR software of the near future, but this is more of a tech-demo than anything else. Of course, it's a free experience, so who's complaining? If you're a new owner of an Oculus Rift headset, you owe it to yourself to download this and check it out first hand.
