Monster Eater [Jared999D]

Monster Eater 1: Karen, the leader of the ME team, went to an old factory after chasing the Orcs. Unfortunately for her, it was a trap.
Monster Eater 2: Jenna followed Karen, but seems to be too late. She heads to the old warehouse to find Karen, but what she finds instead is the worst enemy.
Monster Eater 3: The situation has taken a turn for the worst. Both Karen and Jenna are missing. Dusk and Suzi were searching for orcs to find their whereabouts. Finally, they catch the Orc brothers and when victory is so close, Dusk’s body starts acting strangely.
Monster Eater 3 Add On: The Orcs seem to have left, but now yet another creepy creature appears in front of Suzi.
