The Polis Ranger runs to the surface and has to get materials for the team and you must use different routes and paths to get to the things you need. The Sniper has to be stealthy and has to sneak around enemy bases which is the best chapter in the game. There are also three new weapons in the game the come with each chapter, the Hellbreath, Medved, and Silent Sniper Rifle.
