Manhunt (PS2)

Cheat Codes
The following codes won't work unless you complete both levels with five stars. So really they're not technically cheats, but then they are.

Anyway, each of the codes has two parts, which are unlocked by a specific level (for example the end of level 1 & 2 with at least a three star rank) on the game art that appears.

Enter these codes on the main menu.
Regenerate - R2, RIGHT, CIRCLE, R2, L2, DOWN, CIRCLE, LEFT
Fully equipped - R1, R2, L1, L2, DOWN, UP, LEFT, UP

Unlock Bonuses, Earn Cheats
Earn a three star rating on any level in order to unlock a bonus piece of artwork. As an added bonus, earn a five star rating and each piece of art will have half of a code on it. Combine the left bonus' code with the right bonus' code to get the cheat. Cheats can be entered on the title menu.

See above for the codes in their entirety.
