Portal originally started as a student project! A small group from the Digipen Institute of Technology were working on a game concept called ‘Narbacular Drop’ as their senior project. The project was spotted by Valve Software boss Gabe Newell and they were all offered jobs!
Portal 2 invites you (and a friend) to play with the laws of physics in a fantastically original puzzle game.
There’s lots of ways to explore gravity and other physics topics in Portal 2, so much so that teachwithportals.com even created complete lesson plans that use Portal 2!
