Leech Hunter

Leech Hunter is an unlockable minigame for Resident Evil Zero. To unlock it, simply beat the game. The difficulty doesn't matter.

Objectives
The player must find 100 Leech Charms spread throughout the Umbrella Research Center as both Rebecca Chambers and Billy Coen. There are 50 Green Charms for Rebecca and 50 Blue Charms for Billy. Therefore, they cannot be exchanged. Once the player picks up a charm (10 for each slot) it cannot be dropped. The weapons in the game are also spread out. There's a catch, though: So are the enemies! Also, probably to increase the tension, when the player's total leech count nears 100, some rooms become flooded with creatures, even those rooms that have already been cleared out! To end the game and cash in the leeches, walk out the front doors of the facility. When a character is killed, the game ends and only the surviving character's charm count is accounted for. The prizes are listed below.
