Sentinel skirmishes are won or lost by how quickly you read the four airborne Drone classes hovering above the dirt. Standard Scout Drones investigate mining beams with a blue scan cone before turning hostile; eliminating a lone scout before its countdown ring finishes calling backup keeps your Wanted meter from climbing past Level 1.

Priority targets: Repairers and Summoners

Once Wave 2 arrives, ignore bulky threats for two seconds and hunt the support pair first. Tiny oblong Repair Drones marked by a wrench icon channel emerald beams that restore shattered mech and Walker armour in seconds, while triangular Summoner Drones marked by a Wi-Fi-style signal icon open crimson portals to warp fresh squads onto your flank.

Cracking Heavy Combat Drone shields

Plated Heavy Combat Drones deploy translucent orange energy Riot Shields in front of their rapid-fire scatter blasters. Launching a quick Paralysis Mortar stun grenade paired with the Voltaic Amplifier freezes the entire airborne cluster in place so a Pulse Spitter, Scatter Blaster, or Neutron Cannon shreds them into Pugneum and Salvaged Glass.
