Played a few matches today where members of the other team were hiding in a cave outside the map on DISPATCH, near the tunnel where Defenders spawn to return to the garage. The players can sheet and throw grenades at you, but you could barely hit them in the cave and grenades bounced off the map’s boundary. Once of my teammates tried to splatter the players, but also their ghost just bounced off. Wasn’t a severe issue until the players started pulling out power weapons later.
Going into Theater Mode, it looks like they were jumping off that tower near the crawler by the garage and power-diving to the cliff ledge, and kept power-diving along the edges until they could power-dive past the map’s boundary and into the cave/shadowy area.
