A full Moon appears through a breach in the roof, allowing Chell to shoot a portal at its surface (Cave Johnson said prior that lunar dust was an excellent portal-conducting surface).

GLaDOS makes a plan to force another core transfer in order to return back to her original body, as well as making a deal to release Chell once they do so. Chell manages to escape thanks to her skill with the portal device and a timely splatter of Conversion Gel.Īs they make their way through the maintenance areas, the two come across a cache of un-incinerated corrupt personality cores.
