All hands to battle stations!
The Battle Stations maps introduce you to a military staging area in multiple levels! The corridors and elevator shafts line up to create either a sprawling or a multi-tiered epic gaming environment that recreates the decks of a massive starship, space station, or base facility!
The Command Deck provides operational support and advanced weapons stations along with a hangar for prototype star-bomber development, while the Security Deck offers weapons emplacements, flight control, and a staging area for the deployment of starfighter defenses.
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 alternate configuration for the energy doors on the Command Deck.
