unfortunately, Hellstromme is super vulnerable to Unprepared, moving your shooter down 3+ bullets (-1 for unprepared, -2 for hellstromme, and - the bullet bonus of the weapon).
This makes A Few Custom Modifications even more mandatory than usual.
luckily the designers were smarter than me - on first reading I thought the bullet penalty was even on the defense, and that was frightening. Could be an idea to steal a page from my Raven analysis and design a deck to defensively squat on opposing stuff. although you would still want the gadget weapons to milk the control points.
The other tricky part that I find with this servitor is that I will often want to boot those gadget weapons (Like the mentioned Asyncoil Gun, or the Holy Wheel Gun, or Flame Thrower) - but notably the Auto Revolver, Biocharger Neutralizer, and Shockwave Inducer do not need to boot.
a shame that Post-a-tron doesn't count as a gadget weapon. But Quaterman can ignore the penalty....
