Portal 2

Chell awakens in the ruined Aperture Science facility and teams up with Wheatley, a bumbling AI, to escape. After accidentally reactivating GLaDOS, Chell must navigate new test chambers, solve puzzles with advanced portal mechanics, and uncover the facility's dark history. With betrayal, humor, and clever twists, Portal 2 expands the story and challenges of the original in a deeper, more cinematic journey.
