You'll explore four storylines through dedicated maps. In "Once in a blue moon", Chell seeks reconciliation in space after *Portal 2*. "On the shoulders of giants" is set in the 90s, where a test subject encounters an empathetic Cave Johnson. "A short break" sees GLaDOS granting Chell a surface visit. Finally, "Autoportal Fling" presents an alternate Aperture Science test with automatic portals.
