Attempting to give the sci-fi battlemaps some love, as you mentioned they are frequently neglected.

A3 size and each square is an inch, a good size I think for RPG tabletop games.
I wanted the map to be quite closed in and claustrophobic. Not much room for a blaster in here, it may get very close quarters hand to hand.
You have the engine room, the mess hall, the cockpit and the communications / sensors room.
Plus 3 entry ways, 2 ramps and 1 docking hatch.

WIP so far -
