Boarding. Usually it's done on Transports and Liner's, etc. But it would still be just as intense in space (We do wear flight suits..)
Example: Pilot A Jumps out of his Bomber with a two-handed boarding ram, consisting of 3 prongs of electrically magnetized titanium, and smirks as the ram strikes the glass of the cockpit and electricity zips all over as the glass cracks and bursts open. (Pilot A and B RP a Hand to Hand Zero-G fight)
Did it once (Well.. multiple times) with a close friend and it was always a blast.
