Help: Redline Arsenal Remort Unlock 700 Headhunter remorts Effect Redline Arsenal tightens the old automatic HeadHunter strike substitutions. The per-hit special-substitution chance rises from the historical 3 percent to 4 percent, using Stomp, Thermal Punch, Kinetic Overload or Hunter-Killer Protocol as valid powered replacements. The substituted skill remains part of the current combat round rather than adding another recovery delay on top of it.
