Stand right by the door and use the Chaingun to take out the first two glowy things then use the Drone on the Hunter to destroy rest automatically. This works on all skill levels.
This is pretty much what I did, except I used the carbine for the first part. As long as you stay up against the back wall, under that overhang, it's easy enough to stay alive. Just have to make sure you shoot those glowing parts quick enough.
Easiest Platinum ever.
