AM-AP Rounds aka Anti Matter - Anti-Proton Rounds are ammo manufactured by Koprulu Marine Supply. It is anti-protons packed inside ionized neosteel, both sides successfully having negative charge, causing no trouble. However, if the ammunition breaks upon impact, it will release the anti-protons, which will bind with anything around, creating huge explosion. After initial explosion, the electrons left over from explosion of protons will devastate anything left over. Due to difficulty of harvesting and storing anti-matter, these ammunition will be extremely expensive.
