Upgrading The Alien Grenade

During the training levels, scan everyone that you can. You will find some interesting equipment of the MPs, including adult diapers and condoms.

When fighting the Super Beast, rather than running straight at him, run around in a circle. When he gets near an explosive barrel, shoot it. It does more damage then the BBG. Watch out for his plasma shooting arm as well. When you finish, Edgar will talk to you, and you get to see him.
