As for vacuum, I wouldn't be surprised if most ships evacuated the air from livable areas prior to engaging in combat--you're going to want all crew members already in suits anyway due to the risk of decompression, and at that point you might as well remove the risk of decompression entirely. Plus, during a boarding action, the attackers could easily be exposing the parts of the ship they pass through to vacuum, to make life harder for the defenders--or the defenders could do the same, to make life harder for the attackers (all depending on the exact scenario). In any case, I don't imagine that there will be much infantry combat in anything but vacuum & zero-g environments in space--zero-g's a given, and you're going to have to be fully suited against vacuum anyway in the event your opponent exposes the combat area to vacuum, so you might as well be fighting in a vacuum to start with.
You aren't going to be concerned about decompression, if your crew is in pressure suits and your electronics and other systems are built to handle it. You're going to be worrying about pressure vessel integrity. If there's a slow leak in the pressure vessel it will be of little concern beyond locating and patching it. If there is something severe enough to cause explosive decompression, it is likely severe enough to cause a large amount of physical damage to the crew and structure in and of itself. Depressurising the spacecraft voluntarily sounds like a risky and unnecessary activity, especially in an environment when resources and infrastructure are limited.
I'm doubtful of "long corridors" and many "multiple compartments". Combat spacecraft will mostly be propellant, propulsion, and weaponry, perhaps with a good deal of passive defence as well. Relatively little space will be dedicated to actual crew and avionics.
Unless you meant "vacuum" in terms of "out in the open," which isn't the case at all--in Shattered Horizon, all of the "maps" are in and around stations and asteroids and the like.
Firstly I'd like to mention the absurdity of the Shattered Horizon debris ring...
Secondly, why would you want to fight with infantry in space? That's like having an air force based on people flying paragliders.
I can understand ship-to-ship boarding, but it would be a specialised thing, similar to some of the operations of the Navy Seals, rather than being like infantry IN SPACE.
all i really want is to keep those little grey bastards off my pasture.
As RF said, only a matter of time... though our grey bastards won't be the little ones you might be accustomed to. :thumbup:
It'd be cool to have Sheridan Tanks rolling on the moons surface
Why would you want to have Sheridan tanks on the surface of the Moon? They won't even work there, starting with the most important fact, which is that they will not work without air for the engine...
Space fighters and Sherman tanks? A bit of a technology leap, don't you think?
Space fighters? :facepalm:
