From the website: Prepare for Battle! These maps expand the Battle Station to include the lower deck of the hangar bay that was viewed from above in the Security Deck, and a vast training facility designed to test the mettle of commando squads. Stage a "capture the flag" scenario or infiltrate the base using the cargo hauler docked in the hangar! This double-sided poster measures 22 by 34 inches, and is printed on glossy poster stock. It's pre-folded to 8.5 by 5.5 inches and packaged within a clear resealable envelope for safe and easy transport. Includes a free 5 by 7 inch terrain card featuring an empty cargo bay for the ship, PLUS three bonus, double-sided, 5 by 8 inch terrain cards that reveal the upper deck and outside hull of the cargo hauler, allowing the action to move from level to level within and around the ship in the hangar bay!
