Facility P435
After learning about the ghost merging glitch I started experimenting around with what I could do with it. I tried a few things on sandbox but they never really went anywhere, so I decided to try something in the back area of foundry, and thats how this map came to be. Almost every piece is geomerged somewhere, which it paid off in the end, because it allowed hallways to have a different size than the usual.
Facility P435 is a small-medium sized map located in the back corner of foundry and goes partly into the other part as well. It fits about 2-6 players the best, but 4v4 works fine as well. The weapon layout is pretty simple, the only two power weapons on the map are a bruteshot and a shotgun. There is also an active camo. The rest of the guns are mostly battle rifles, but there are a few assault rifles and one pair of smgs and spikers. The map is set up for KOTH, oddball, CTF, assault and of course slayer.

As requested, heres an overview. It is very rough, but it helps show the layout.
1st. Floor is Blue
2nd. Floor is Green
The original map geometry are the black lines
Gray areas are places that cant be reached
Stairs are red
Blue with green lines means there is a first and second floor in that spot.

The main area, near the defenders base, this is where most of the action occurs

Another shot of the main area

Some of the hallways below the main level (note how almost every piece was geomerged)

The hallway that leads from the main area to the attackers base if you keep going.

Another shot of the same hallway from the other end, by the attackers base.

The active camo which is located in the middle of the hallway in the previous pictures.

The defenders base, it looks small, but back hallway is open too, which is plenty of space.

The attackers base, pretty straightforward, a room with some boxes in it. You can't see it, but you can jump on a box to get to the back hallway, which then leads you to the main area.
