List combinations of skills we've never seen before: Rem Pres, Structure and Regeneration. Basically, a literal transformer... Rem Pres on Wounds. Controller is relatively new but Controller on Wounds, pretty Sepsitor or Psychic Puppetry. I feel like Nanopulsers and Viral should be continuous damage... Where an Acid Weapon should be the single BTS roll.
Acid depletes itself regardless of how resistant or not a material is to it, acid needs material to react to, once the molecule of acid completes its reaction with the material it comes in contact with, its done. That being said, acid han be semi aerosolized so that it can be used as a grenade and it can be put into projectiles. I would make Acid an AP/DA Damage 14 ammo that hits ARM though. Nano is self powered and can function like viral if it is, viral is self replicating using material found in the host. I'd make nano basically like fire but BTS save. Viral the same but DA. Obviously these changes would make some troops powerful AF so I'd limit it and replace it with just something called BioTech rounds that are BTS saves. That or lower the damage on nano and viral to compensate for how deadly they'd be. At least their names would match their game play then. I would make the explanation for BioTech ammo as anyone can create a generic highly toxic and contaminated with bacteria material. Lower damage is cheap higher damage is professional. And honestly ammo types should be applicable to any weapon in the game. Ex: Viral Rocket Launcher Nano Missile Launcher Incendiary rounds. (Just continuous damage with ARM saves...)
