I was playing an Oculus Rift game where you had to fly really fast through an environment but I was stuck on a really hard level. The level was a small section of a city with a dull grey cityscape and the ground was littered with hostile zombies, rat-people, and greyhounds. The way the game worked was that you had to zoom through a massive obstacle course and tilt your head to change the direction you moved. You could also use the controller stick to increase/decrease your speed. There were power ups you could buy at the start of the level too. For example, there was one where you would have a companion NPC that walked around the level and you could teleport to them whenever you wanted. The game also had a recon mode where you could just go by foot and fight the hordes of enemies.
