Commissar is amenable to that arrangement, if Mr. Acros finds Freight's quarters to his own satisfaction.
His choice of weapons will be limited to weapons that will disarm and incapacitate, not grievously injure or kill. Removal or amendment of the two weapons in the engine room must be cleared with another crew member (Preferably Commissar) before things are taken out of the armoury. Projectile weapons or other energy-based weaponry must be locked to his heat signature, so one weapon cannot be misappropriated against him or the crew if a situation arises like Freight envisages. Commissar is not interested in arguments that heat-locking makes guns and vibroblades and the like take ridiculously long to "sign on"; if Freight finds that arrangement unsatisfactory he may carry non-energy based weaponry instead.
Plasma weaponry is not permissible without extenuating circumstances in the engine room (which is a bad place for bolts of plasma) or the cargo hold (which is potentially a place full of things which are bad for bolts of plasma). Commissar defines "extenuated circumstancings" as enemies who are shown to be resistant to all other available forms of weaponry.
Commissar is pleased, additionally, that Freight will follow the health and safety directives when travelling the corridors, regardless of what sort of weaponry he has been entitled to.
