There's an asteroid storm coming for the space station, you're going to have to protect the space station as best you can.
Use your pistol to shoot the asteroids, to keep as much of the space station intact as you can. On the left side of your gun there's a reading of the percentage of the space station still left. If it hits 0% - it's game over.
good game. This is a very enjoyable game. can be played sitting or standing, sitting is great if you have trouble with motion in VR, love shooting the asteroids and seeing the world from the space station. The power-ups are a nice touch... A couple more power-ups might be handy...
