Step 1: Assemble the Core 4-Piece Striker Set (Including Chest & Backpack)
Equip 4 pieces of Striker's Battlegear: Chest (increases max stacks to 200) and Backpack (increases damage per stack from 0.65% to 1.0%). Fill the remaining two slots with a Grupo Sombra piece for +15% Crit Damage and the exotic Coyote's Mask.
Step 2: Reach the Golden 50-55% Critical Hit Chance Cap
Calibrate your gear attributes with Critical Hit Damage on all pieces while keeping Critical Hit Chance between 50% and 54%. Coyote's Mask automatically grants +10% to +25% CHC to your entire team depending on target distance.
Step 3: Pre-Stack Strikers with an ACS-12 Auto Shotgun
Every shotgun pellet grants an independent Striker stack. Firing a single drum of an ACS-12 shotgun into a heavy tank or chokepoint builds 100+ stacks in under 2 seconds before swapping to St. Elmo's Engine for laser-accurate DPS.
Step 4: Execute Challenging Countdown Countermeasure Objectives
In Countdown, never rush the main mission first. Stick with the 8-player group to disable the 3 red Countermeasure terminals (Hazard Protection and Skill Damage buffs), melt all 4 VIP Hunters with Jammer Pulses, and extract at the Helipad.
