Portal 2: The history of Portal
Portal 2 is a first-person puzzle-platform video game developed by Valve Corporation. Like the original Portal, players solve puzzles by placing portals and teleporting between them. Portal 2 adds features including tractor beams, lasers, light bridges, and paint-like gels that alter player movement or allow portals to be placed on any surface.
