Level 1/ LFE Gun / Pulls out the LFE gun and shoots a huge ball of energy foward. Ball moves very slowly but is very large, a little bigger then big daddy.
Level 2/ Robbert Burns / Sam calls in Burns to help him. Burns would be similar to kuma, only he would have no close ranged attacks. He would use his minigun to attack players at any range, but he has a slow start up so it could be easily avoided.
Level 3/ A.R.S Mode / Sam says into his helmet radio "Fire it up Elena!" and he goes into A.R.S mode and slows down the entire match. Similar the the A.R attack, everyone is slowed down, and Sam is slightly faster then everyone else. Now all his attacks will instantly kill players.

I noticed something while making this move set. Sam and Nathan are very alike. Not gameplay wise but character and game wise. They have the same kind of sandpaper personality, they both use cover, and in their games, they both have a important character with the same name. Elena. **bleep**.
