So there is a tunnel just outside of objective D on HILL 937 that looks destroyed. The objects used ARE NOT SOLID and allow players to phase through but the rocks stop bullets, traps and spawn tunnels from being built. You can stand on the end of the map in this tunnel and shoot through the floor killing anyone you can see. I managed to stand on the edge and lean around the corner allowing me to basically kill anyone. THIS IS NEEDS TO BE FIXED ASAP. sorry about the photos, for some reason steam wont let me take a full screenshot.
