Walkthrough step-by-step
Fight the Hedron
To save Manhattan, there is only one thing left to do — kill the Hedron. Back in the Unknown after the previous mission, make your way to it: go to the northwest point where a gravity well is and use it to drop toward the Hedron on the far west of the map. Once you land, the Hedron fight begins — a three-phase fight across three arenas with a health bar per part. You never fight the Hedron directly; you fight the smaller enemies connected to it, draining the health bar instead.
Phase 1: The boss alternates between shooting projectiles from the side of the arena it is on, then sending the enemies to the arena's center where you can attack them. After a handful of smaller enemies, heavy enemies spawn that typically stay in stationary spots — these also feed the health bar and must be defeated. Once the bar is depleted, press the prompt to finish the Hedron, then again when you are transported into the core.
Phase 2: The boss fires lasers at the ground near you — keep moving to avoid them. It keeps sending small enemies onto the platform; they move back and forth across the arena while shooting lasers — hit an enemy to stop it so you can attack it. There are now two areas in the arena: after dealing half the health bar, move to the other arena (it spawns half the enemies on each side). Use Reach to grapple to the airborne platforms on either side, then across to the other area. Defeat the enemies there, then kill the center of the Hedron and the core again. At 75% health it launches waves of lasers to jump or hover over; more enemies and sawblades spawn, and you get the execution prompt again at zero health.
Phase 3: A new arena — enemies spawn periodically, and the bigger ones must be taken out to damage the bar. Avoid falling into the void. After the third execution, the Hedron is gone for good and you return to the Gap.
