This map started as an idea I had based around surviving a ship crash. Eventually I developed the idea a little further: Basically the ship is a cargo ship that mysteriously ran into some serious problems while traveling in close proximity to a relatively unknown planet. The planet is largely unexplored except for some minor mapping and probing surveys which turned up nothing of interest. The cargo ship is actually somewhat of a mercenary vessel. The ship's captain was drawn to the planet because reports of numerous ships being lost near the planet surfaced. Thinking he could find easy scrap he decided to investigate. Unfortunately something happened once the ship began to orbit the planet. A massive explosion rocked the ship and its orbit quickly began to decay. Once it hit the atmosphere the ship began to break up due to damage caused by the explosion. It crashed on island filled with mysterious structures. Now the survivors must escape their crashed ship and try to solve the mystery of their crash.

Overall I built this map to look cool. I built it based solely around the ship at first then expanded it to include a few structures and other scenery in order to make it more interesting and playable. All the weapons and objective points I added were just to give a general idea for a playable map, definitely not set in stone. Below is an aerial view of the map, not shown is what brought down the ship on the other side of the mountain:

First the ship. The ship has two distinct sections. The stern section has many little goodies including a small transport craft for scouting and exploration purposes. The bow section itself is a goodie because it is a fairly good sniper post but beware a few well aimed counter-sniper shots could dislodge you from that post.
This image is a closer view of the ship:

Second the Forerunner vehicle depot. It's to left of the crashed ship on a little island. It has two Revenants one in each garage section. It also has defense turrets mounted on a tower behind and connected to the depot as well as other weapons.
This is the front of the vehicle depot/bunker:

Thirdly the Forerunner guard towers. It's further to the left of the crashed ship beyond the vehicle depot. It has multiple goodies there for those that can reach it including health.
This a front view of the Forerunner guard towers:

Side note-the half a dish on the rear side of the towers is functional, it was added after play testing because the top tower was a tad too difficult to reach. The dish allows you to scale it more easily.

Fourthly the bridge on the right side of the crashed ship. The bridge was added to allow for a bit more playing area, also as an objective spawn. The bridge also has hidden goodies around it as well as the central mountain.

Lastly the mystery behind the mountain. All I will tell you is that this is where blue team spawns as compared to red team which spawns within the crashed ship.
