UPDATE: more refined version
Its 2779, Weyland-Yutani are transporting precious minerals to help build up a settlement on the forest moon of N37. The ship is an Old transport ship, highly armed and customised to be protected against any interception. It crosses into the greyest areas of the galaxy like a hulking cityscape. A titan of the sky’s. These minerals are vital to the settlement’s survival and expansion into the forests… and the predator Ship yard on N37.
The predator’s have a plan. The mineral’s are to precious to let the humans have, Tough as a rock and light as a feather. To make it more interesting the predators are going to make sport of the mission, Releasing aliens on to the ship to kill of the humans, then hunt the aliens.
The ship is large and well lit with 3 main rooms. The armoury is, dare I say armed to the teeth. With Gatling guns mounted at every entrance and blast door’s that close in 3 seconds it is truly impenetrable. It is equipped with every gun man can think of and them some. The most impressive being the KZ3 Prototype, A hulking gun that fires the equivalent of a tank round. It hangs by the waist and hangs on the shoulder weighing in at 200 pounds.
The storage room is huge craning over 100 ft in the air with boxes stacked to the sky all filled with tons of the mineral. The room is re-enforced to withstand a chain-gun bullet and To protect the precious cargo it had 3 mounted on the roof. As a last option it Can incinerate all within the room. Good thing the boxes are resistant!
The last room is the control room, 8 guards on every corner and only 2 entrances, with various vents but that wont be a problem… The blast doors will only ever be opened by someone one the inside, The guards protecting it are full blooded marines, Minimum of 9 years service they are all battle hardened.
The lights have been cut; The predators have breached the hull and released a assortment of aliens. Fully cloaked they make their way to the cargo. Aliens are in the ventilation, The humans have flooded to their stations. Half of them are just waking up.

You just got out of bed by the way!
