So, against all odds, one of my players succeeded in upgrading his vibroknife with the mono-molecular edge, all its mods, and the Superior Weapon Customization. Having done this, he made use of it in the next adventure...and immediately started throwing down crits like nobody's business. Now, we all know minions just die when they suffer a crit. The question is, can one attack that generate multiple crits kill more than one minion? Against other opponents, multiple crits would just add +10 to D100, but minions don't have to deal with that.
I allowed it during this session, but warned that depending on feedback, my ruling on the subject might overturn.
