20 Essential Video Games You Must Play Before You Die

15. Portal

Almost an astonishing 8 years old now, Portal was the title that dared to take something as old fashioned as a puzzle game and revolutionise it for modern consoles.

Under the simple premise of being a lab rat of sorts in a testing facility, the player is given a Portal Gun - a device that is capable of creating two openings of a doorway on any flat surface you aim it at - and given a series of increasingly devilish rooms to work their way out of. With promise of cake at the end of it all.

One of the most original games ever conceived, Portal's physics, gameplay, and focus on ingenuity means it's still one of the most addictive titles you can find even to this day.
