I have a basic sketch of the level I would like to create, with this set aboard a ship I have allowed a spacious area where storage creates are held to allow for climbing, sniping and close encounters.

 off to the sides of that are the corridors which will be then focused close/medium combat with some side rooms to allow survival during these encounters and objects to hid behind.

 another spacious area being the kitchen where there will be obstacles once more aiding both for and against the opponents as they fight for the better weapon spawns, a side room branching off here as well for more survivability and for the player to be more cautious for.

 Right now there are stairs leading up to other levels and down to other levels but depending on how big this is in UDK they may not be needed.
