What happens

You wake in the Aperture Science lab and solve test chambers with a gun that makes linked portals on walls. GLaDOS, the AI running the tests, offers encouragement that grows more suspicious by the minute.

Who will love it

Anyone who likes puzzles and dark humour. It runs on almost any computer.

Learn by playing

Each chamber teaches one new idea. By the end you are doing things that seemed impossible an hour before.

GLaDOS

The AI narrator is one of gaming's great characters. Listen closely.

Tiny price

Portal is often on sale for very little and runs on old laptops.
