I'm curious, has anyone here ever run a scenario with tactical action onboard a spacecraft? For example taking over a hostile Merchant Jumpship, or sneaking around inside an enemy Mule. If so, how did you go about providing maps of the ship's layout? Did you find maps from outside sources such as Traveller, roll your own, or just use descriptive combat to avoid detailed objective maps altogether?
Myself, I'd pay goooood money for a nice set of spacecraft interior maps in Battletech, especially ones that were designed by an engineer who "did the math" on appropriate space needed for fuel tanks, transit drives etc., but as far as I know, no such beast exists. One of my favorite aspects of BattleTech universe is the avoidance of most magic-tech. Sure no physically possible drive could get the fuel economy of a Behemoth dropship but there are no energy shields, no transporters, and down is toward the engines instead of the grav-plating.
Because of it's unique approach, BattleTech spacecraft have a layout all their own. So has anyone ever seen maps for one or more ships at a scale appropriate for RPG play?
