Help: Kill-Chain Protocol Availability Headhunter with 100 or more class remorts. Description Kill-Chain Protocol is a special combo sequence for Headhunters. Arrange three distinct eligible attacks in this exact tactical order: 1. CONTROL - Tripwire, Servo Lock, Hydraulic Stomp 2. BREACH - Heat Sink Breach, Metal Auger, Thermal Punch 3. EXECUTE - Kinetic Overload, Hunter-Killer Protocol, Chainsaw Dervish Sample Combinations combo servolock heatsink overload combo tripwire auger chainsaw combo hstomp tpunch protocol Use combo skills to check your eligible abilities. Existing unlocks, skill requirements, follow-up checks and the four-step combo burst budget still apply. The special chain does not guarantee every attack succeeds. Follow-Up Chances (second / third stage) 100 remorts: 35%% / 25%% 500 remorts: 45%% / 35%% 1000 remorts: 55%% / 45%% 1500+ remorts: 65%% / 55%% A successful chain displays distinctive BREACH and EXECUTION messages. The chain strengthens the follow-up sequence rather than creating an additional independent attack or a separate finishing-damage proc.
