You pick up a sniper rifle and then you go to the fusion coil, you jump on the fusion coil, you then jump and shoot it at the same time and you will land on a ledge perfect for sniping.

You do the same as last time except you move the fusion coil towards the two plasma grenades. You stand on the fusion coils, then shoot it and jump towards the high bit in the middle and you can snipe eeryone from there.

You do the same again except you move the fusion coil half way towards the plasma grenades. If you look at the big tree trunk that is right beside you you can see there is a big stickin out bit of the tree. You shoot and jump onto the ledge bit and run all the way up to the top.

These are all really good sniping places that you can do on matchmaking as well once you get better and faster at it.

Tip: remember to jump and shoot at the same time.
