Mainframe Lock room

This prefab occurs in the OMNI Mainframe mission. It is a 5×7 rectangular room with distinctive decor, containing the Mainframe Lock; at the back of the room is a special three-tile-wide door which only Monst3r can unlock using the Mainframe Lock. The room is connected to the rest of the facility by only one door, although very rarely it has a second door leading to the Security Hub room.
