Hi, thanks for your comment. But instead yelling you could give us more specific information for fixing issues.
Are you using SteamVR with the Rift or the native implementation (you can see this if the SteamVR popup is open and active)?
Have you used the teleport or the walk mode?
Is your VR headset correctly calibrated? Can you touch the floor in other games?
You can't reload the weapons that's part of the story. Therefore you get new weapons over time. So you have to think about shooting.
