The map layout is basically a large horseshoe around the central area. The horseshoe is made up of rooms and corridors at different elevations. There are also balconies jutting out over the central area. The central area is made of 2 layers of gears and then an upper layer of vents. The over sheild is on the bottom layer which has numerous routes up to the middle layer where the sniper rifle spawns. Red team spawn in a corridor in the horseshoe to the left of one stronghold which is on a lower balcony near the sniper. Blue team spawn on a balcony at similar elevation with a drop down to the 2nd stronghold found on the lowest balcony by the over sheild. The final stronghold is along the back end of the horseshoe on an upper balcony at the height of the vents. Vents cannot be entered but can be walked across and some with steam coming out act as man-cannons.
