Resident Evil 5/The Mercenaries

The mercenaries is a score attack mode which is unlocked when you complete the game. To begin with, only two characters and one level will be available, but others can be unlocked by achieving sufficiently high scores.

Rankings
Your rank on any level is awarded based on the number of points you score. In a Duo (co-op) game, both players' combined scores are counted for the rank.

Depending on the rank awarded, you will receive a number of Exchange Points to spend on Bonus Features.

Characters - Chris Redfield (B.S.A.A.)
How to unlock: Already unlocked from the beginning of the game.

Strengths: Shotgun can hold 20 bullets which is high for a shotgun. Starts with a first aid spray. Grenade is excellent for groups of enemies and bosses.

Weakness: Weak pistol. Shotgun doesen't deal high damage.

Overall: Chris is nothing special. His weak pistol should be discarded to find more ammo for his shotgun. Though even his shotgun isn't very damaging at close range. To make up for this, the first aid spray will keep Chris at 100% health and his grenades deal high damage.

Chris Redfield (Safari)
How to unlock: Achieve an A rank or better in the Village.

Strengths: Starts with two instant kill rocket launchers.

Weakness: His shotgun does the same damage as BSAA Chris' but has 10 less bullets.

Overall: A decent character. His pistol does medium damage and his two rocket launchers are great for killing bosses. However, that's it. His shotgun is a down grade from BSAA Chris.
