Aperture Science Enrichment Center (Wheatley's Domain)

Portal 2 guide · Returning to the surface

Chell and GLaDOS (attached to the portal gun as a potato) ascend back to the modern Aperture facility to confront Wheatley, who has taken control of the complex and is driving it toward a reactor meltdown. You must navigate Wheatley's redesigned, slapdash test chambers and ruined maintenance areas to reach the central AI chamber for the final battle. Solving these puzzles requires combining excursion funnels, light bridges, and all three mobility gels with dual-portal placement.

Automated tripod guns that fire continuously once they detect you in their red targeting beams.

Defective Turret

Stripped-down, non-functional turrets that cannot fire live rounds and are used as corrupted core inputs during the final stalemate confrontation.

Wheatley

Weak to Attaching corrupted cores and shooting a portal onto the moon

The main antagonist who attacks from the central core chassis using shields and bombs, culminating in a stalemate resolution.

Tips

Listen carefully to Wheatley's dialogue during his test chambers, as he often reveals his traps or inadvertently hints at what he is trying to stop you from doing.
In the final boss encounter, use Wheatley's thrown bombs against him by letting them hit portal surfaces so they redirect back into his chassis to stun him.
When the ceiling breaches during the finale, look directly through the hole into space and fire a portal at the moon to trigger the vacuum ending sequence.
