Abilities
Active Ability
Defender System
Deploy a defensive platform that harmlessly neutralizes incoming explosives. You and nearby allies gain increased weapon stability and reload speed while standing near the device. The platform has a limited number of projectiles it can intercept.
Passive / Tactical
Castle Doctrine
You ready and reload SMGs, Pistols, and Shotguns more quickly based on the number of nearby hostiles. When you take splash damage, your Hardware, Firewall, and Self-Repair Speed are increased for a short time.
Passive Traits
Prey Tracker
Activates motion tracking in your HUD, letting you see moving enemies on radar within a conical zone in front of you.
Field Analysis
Recommended Playstyle
Anchor a position with Defender System protecting your crew from grenade and rocket barrages. Use Snare Mine to deny pushes through choke points and around exfils. Castle Doctrine rewards holding ground over chasing kills - let enemies come to you, and the close-range handling buff makes the KKV-9SD and D54 Battle Pistol especially strong when surrounded.
Strengths
+Strong area denial and zone control
+Counters grenade/rocket spam (Defender System)
+Synergizes with close-range weapons via Castle Doctrine
+Excellent for defending exfils and choke points
+Prey Tracker gives free intel on enemy movement
Weaknesses
−Reactive playstyle - struggles when forced to push
−Defender System has limited charges
−Less mobile than aggression-oriented shells
