Dead Rising Deluxe Remaster

On day 2 you'll walk out of the safe room and see a cinema with a bunch of yellow jacketed cultists and a cult leader from that point in every part of the mall it will start spawning groups of them. Simply kill 100 of them easily done with weapons like Adam's small chainsaw or katanas.
Be careful of there attacks they can stun you with gas and capture you or if they run at you they can jump and explode but nothing to crazy if you keep an eye on the group.
