The Wheel Cutter is a circular saw that can be used as an attack and as a means to climb a wall. When shot, the Wheel Cutter goes through the floor, going up in walls if it crosses with its path. When used over a wall and not still released, the Wheel Cutter pushes the player character over a wall so it can climb it.
Wheel Cutter projectiles tend to bounce for a while while traversing terrain, and can take time to go over walls. While the projectiles do not despawn if used melee, they do if launched.
