Aperture Science Enrichment Center (GLaDOS's Domain)
Portal 2 guide · The final confrontation
← All areas in this guide
In the final chapter, "The Part Where He Kills You," Chell confronts Wheatley in the central AI chamber as the facility approaches reactor meltdown. You must redirect Wheatley's bombs to stun him, attach three corrupted personality cores provided by GLaDOS, and initiate a core transfer. The battle culminates in firing a portal at the moon when the stalemate resolution button is sabotaged.
Enemies
Wheatley
Weak to Redirected bombs / Moon portal
Controls the central AI chassis, attacks with bombs and shields, and is defeated by moon portal exposure.
Tips
- Place one portal beneath Wheatley and another where his bombs are landing to fling explosives directly back up into his chassis.
- Use the excursion funnels that activate after stunning Wheatley to float up and manually place the corrupted cores onto his body.
- Keep an eye on the facility countdown timer, as taking too long during the final confrontation triggers an immediate reactor core explosion game over.
- When the ceiling breaks and GLaDOS tells you to press the stalemate button, look through the ceiling hole into the night sky and shoot the portal gun directly at the moon.
