On zm_snow_camp_v1, you can access the top of the tower that does not have a teleporter. This is possible by shooting a bookcase up there and letting it hang off the edge and getting boosted up via another player. Since zombies cannot stack up there without a prop or bhop there from the launcher i think this should be illegal. It is impossible for zombies to get a prop up there. Let me know what you think. I will attach photos of said spot.
