The gold standard of puzzle games. Portal 2 elevates a simple physics-based mechanics loop into an exceptionally witty, narrative-driven masterpiece, supported by brilliant environmental puzzle design and a stellar co-op campaign.

Portal 2 is a masterpiece of first-person spatial puzzle design that expands the original's brief concept into a full-scale, narrative-driven adventure. Set in the decaying, massive Aperture Science laboratories, players manipulate space using a Portal Device that fires blue and orange gates on flat surfaces, allowing momentum-based physical traversal. Puzzles require manipulating physical elements: redirection cubes that guide laser beams, aerial faith plates that launch you across chambers, and three distinct elemental gels (blue propulsion gel that increases speed, orange repulsion gel that causes bouncing, and white conversion gel that allows portals on previously un-portalable walls). Puzzles are highly logical and rewarding, featuring perfect onboarding that teaches complex momentum conservation without explicit tutorials. It also features a fully distinct, highly challenging two-player cooperative campaign where players must coordinate four portals, requiring tight vocal communication and spatial synchronization. Outstanding on the Steam Deck and Switch, where it runs at a locked 60fps.
