A while ago in my Ship Shape Map Pack thread, BWO Ironskull made this post.

Very cool, I like the idea of ship custom maps. It's something totally different to board a Cruiser and try and take it over.

My idea was to build a huge ship and one team defends it and the other team starts way off on another side and has to fly in and land on it and then they have to make way to the control room and take it over, basically have the game set up for territories that the attackers must take over, after they do they control the ship (game over)."

Needless to say, my forge senses started tingling. I knew I couldn't leave a map like that unmade. So I immediately started laying my plans for this. After an incredibly amount of hours working I finally finished. This is the result of that work.

The UNSC Iron is a unique map with a very unique gametype (Territories is all you need to use). Attackers spawn off to the side of the map next to hornets. They must fly these hornets onto the landing pad attached to the back of the ship, then board it! There are 8 rooms in total, from the front; Bridge, bridge room, reactor room, engine hallway, mauler room, mauler hallway, engine room, and the cargo hold.

Bridge

Defender's spawn and generally last territory. Connects to bridge room and cargo hold.

Bridge Room

Acts as the connecter from the bridge to the reactor room and engine hallway.

Engine Hallway

Spans from the engine room where the attackers enter to the bridge room, this hall has only the cover offered by the engine cells available. Be warned however, if one of the cells detonate, the rest will as well.

Reactor Room

Holds the UNSC Iron's reactor, at 10 seconds in the third fusion coil will activate, and the reactor will start running. Connects to the Bridge Room, Mauler Room, Engine Hallway, and Mauler Hallway.

Mauler Room

Home to the only weapon on the map, the mauler room is as close to the center of the map as you'll get, and connects to the engine hallway, mauler hallway, and reactor room.

Mauler Hallway

Barely suitable to be called a hallway, this area connect the engine room to the mauler and reactor rooms.

Cargo Hold

Part of the uniqueness of the ship, the cargo hold spans the entire lower level of the ship, connecting the engine room to the bridge. Cargo boxes stacked around make for over a dozen places to hide, making this territory the hardest to capture.

Engine Room

First place the attackers will enter when they board, and connects to the cargo hold

, engine hallway

, and mauler hallway

Iron's Gametype (Territories)

Territories with a twist, every room in the ship is a territory. No spot can be ignored, no room forgotten. Blood given for every inch taken.

Supports up to and best played on 6v6, it is fun to play down to 4v4.

My bad, I should add that I've downgraded it to a bare minimum to fit the budget. There used to be a duct system between rooms :'(
