Thanks for the flying game suggestions, but I think I'd rather have all four wheels on the ground.
Recently I've finished Budget Cuts and with a third sensor it really gets a whole lot better with the ability to turn around and face any direction. Overall it was a fun stealth game. You really have to get low in real life if you want to avoid being seen by enemies and to even fit into ventilation shafts! After crouching for long periods of time I figured I could just sit down on the floor instead.
Another "cool" trick I did was in Superhot VR. It was endless mode where you kill enemies until you die. In one of the stages there was a pool table right next to you and nothing stops you from laying on the floor under it shooting anyone brave enough to come close. I bet it looked like I was the laziest VR player ever.
Killing Floor: Incursion is sort of a mix of a horror game and a shooter. At first it's terrifying but as you get more weapons it turns into more of a shooter. Even the easiest cannon fodder enemies from Killing Floor 2 suddenly get a lot scarier when you are staring at them at eye level. Supports both teleportation movement with a cooldown and using the left stick to move. Quite difficult at some parts, could be easier in co-op. It's ok but could have been better. There's only a few guns, no classes with their special abilities, very small maps, fewer enemies than KF2... I got it on sale for 9 € which was a very good price for this.
Arizona Sunshine is another zombie shooter I bought during the Steam sales but haven't started yet. It's one of the best selling VR games so my expectations are high.
