Another ideas thread from the crazy, disputed mind of Talon.

Just to make space fights that little bit more interesting, how about having extravehicular capability. Only the engineer, equppied with an unlock (except you'll get it from the start as theres no points) has full capability, with a jetpack. He can use his weapon in space, allowing him to attack other spacetroopers.

Other classes, or if he doesnt select that option, can have a capability which grants them 60 seconds of air before they die. This gives them time to float towards a hangar, if they're lucky enough to be facing that way (some directional change could be added to give them a chance). There can also be an option to unequip the mask, dieing instantly (to prevent boredom).

To enter space, one can eject from a ship, or simply jump out the hangar force field. When ships are close, this could be a good boarding method.
