...Everything is permitted. Especially when you have a Mjolnir in their base, killin their doodz.
Once you accomplish the primary objective by nuking the shuttle with a mjolnir, it is possible to continually use said mjolnir to kill Artemis station, the nearby Aeolus, Hippocrates, and a get few shots off on the Atreus and the Deimos before the turret mysteriously stops shooting (out of range maybe?). At no point do fighters swoop in to kill the damn thing.
While most players may just jump out and leave immediately, since I was never detected, I wanted to see if the briefing takes into account you trashing Artemis station and a bunch of capital ships. Apparently not. Also, dear lord, those Mjolnir's have the damage output of BFReds or something.
