A map with lots of tunnels, in the tunnels are swinging spiky balls, swinging saw blads, horozontal saw blades, crushing walls, spiked walls, in the centre is a device that has a redeemer in it, but if anyone gets caught in the middle it will depressurise you to death, all ammo is in cells, again if you get caught in a cell you will be depressurised to death lol
