Effect: ADAM vs. Jack
When:
no need
How:
This battle is different than when Angela fought ADAM. He will now stand in the center of the room and shoot lasers at you. The red ones are easy -- hide behind a wall. For the blue ones, you have to guess where it is going and get out of there. When defending yourself against ADAM in Phase 1, instead of hiding behind a pillar or dodging his blue attacks, hide behind the computer panels. When he attacks with his red ray, hide behind the pillars and he will not hurt you

Effect: Defeating Greywolf
When:
During The Game
How:
You can easily defeat Greywolf on the roof of his hideout by using Proximity Mines. Just place one near where you enter the roof, and as he circles around he will set it off taking a large amount of life. Just be careful not to set it off yourself. When your mines are down to one, start sneaking behind him then take a few shots and head for cover. Use the one mine you saved for when he gets low on life, because he will back himself into the gap in the corner directly across from the entrance and stay there shooting nonstop. Place a mine in that area beforehand and when he goes there he will set it off, dealing the final blow.

When:
During The Game

Effect: Attacking ADAM in Phase 1, 2, and 3
When:
During The Game
How:
During the time in which ADAM is not attacking you in Phase 1, do not shoot him with any other weapon besides the sub machine gun. There are boxes with the SMG ammunition available during that fight. In Phase 2, do the same thing. In Phase 3, shoot ADAM with your missile launcher as he approaches you. This will slow him down. Then, run to the Judgment Cannon (ADAM's weapon).
