About Portal 2

Portal 2 draws from the award-winning formula of innovative gameplay, story, and music that earned the original Portal over 70 industry accolades and created a cult following.

The single-player portion of Portal 2 introduces a cast of dynamic new characters, a host of fresh puzzle elements, and a much larger set of devious test chambers. Players will explore never-before-seen areas of the Aperture Science Labs and be reunited with GLaDOS, the occasionally murderous computer companion who guided them through the original game.

The game’s two-player cooperative mode features its own entirely separate campaign with a unique story, test chambers, and two new player characters. This new mode forces players to reconsider everything they thought they knew about portals. Success will require them to not just act cooperatively, but to think cooperatively.

Extensive single player: Featuring next generation gameplay and a wildly-engrossing story.
Complete two-person co-op: Multiplayer game featuring its own dedicated story, characters, and gameplay.

Steam Summer Sale 2026 in its final hours: last chance for big discounts

Steam Summer Sale 2026 wraps up today, 9 July 2026 at 19:00, so this really is the last call for some heavy hitters at a fraction of the price. I picked games that normally sit in the 100–300 zł bracket and now cost about as much as eating out.

Is it safe to buy a Portal 2 Steam key from a keyshop?

Keyshops are marketplaces that resell game keys, usually below official store prices. The keyshops listed on KingsPrice deliver genuine Steam keys, but buyer protection differs from official stores — check the shop's rating and refund policy before buying. You can hide keyshop offers at any time with the keyshops toggle. Keyshop prices vs Steam →
