Portal
Portal™ is a new single player game from Valve. Set in the mysterious Aperture Science Laboratories, Portal has been called one of the most innovative new games on the horizon and will offer gamers hours of unique gameplay.
Is Portal good on the Steam Deck?
On the Steam Deck, Portal behaves like a title built for handheld play: it plays on controls and needs no manual setup to get going. Being an action title, it makes good use of the Deck's physical controls — the kind of game you fire up for a quick run when you have a few minutes. With a Metacritic score of 90, it's among the best-rated in its category — a safe pick for your Deck library.
Is Portal worth buying?
Portal's Steam price is $9.99. Before buying, it's worth comparing the digital key on Instant Gaming or G2A, which often land below the official store. It's already budget-friendly — exactly the "cheap gem" range we look for on the Deck — but it still pays to check before buying. Since it launched in 2007, discounts are common, especially on third-party keys.
