Heavy armoured cavalry arrives across the final two rungs of the Wanted ladder. Level 4 drops a Hardframe Battle Mech straight out of orbit on jetpack thrusters, unleashing plasma grenades, stun mortars, and sweeping flamethrowers before yielding a Hardframe Engine. Surviving into Level 5 summons the towering bipedal Sentinel Walker to anchor the climax of the planetary battle.
Two-phase Walker armour stripping
Firing blindly at a fresh Walker's chin bounces harmlessly off invulnerable plating until you dismantle its armour in order. First, blast off all four destructible leg plates across its shins and upper thighs (clearing Repair Drones first so they cannot weld plates back on!) to stagger the giant. Second, shatter the upper head faceplate to expose the vulnerable brain casing underneath.
Dodging mortars and claiming Walker Brains
Whenever clusters of red target circles paint the dirt around your boots, sprint or melee-boost clear of incoming plasma mortar volleys and duck behind terrain during its sustained tracking beam. Felling the Walker drops a coveted Walker Brain (plus extra brain salvage via Mining Beam on the wreckage) for Conflict Scanners while shutting down planet-wide patrols.
