Portal 2

Portal 2 is Valve's puzzle game: Chell is back in Aperture Science with Wheatley and a returned GLaDOS. Portals, gels, light bridges and the excursion funnel sit between story beats and test chambers. Co-op on two robots is a separate level branch for a pair. The Workshop has kept community maps alive for years after the credits. It launched in 2011. Solo and co-op do not share chamber progress. The lines were newly recorded, not a voice mod on the first game. Buy a Steam key and take the portal gun right after activation.
