Portal 2 Walkthrough

Welcome Back to Aperture Laboratories. — In Portal 2 players awake in the Aperture Science Labs as Chell, the heroine of the original game. A great expanse of time has passed since the conclusion of the first game and the gameworld has fallen into visible disrepair, but placed in suspended animation, Chell has survived intact and is revived. With the help of a robotic entity the concluding events of the past game are revealed and you escape your initial confinement, but in doing so GLaDOS, the the AI computer antagonist from the previous game is also reawakened. Just as fickle as ever, GLaDOS’ motives are unknown. Insisting on testing you, it may assist you but may also be planning something more sinister.

Like the original game, Portal 2 is a first-person Platform-Puzzle game. In the single player campaign players assume the role of Chell, a former test subject trying to gain her freedom from the Aperture Science facility and GLaDOS, the AI controller of the facility. Set in the test chambers of the facility your goal is to make your way through the game levels using your portal gun (the Aperture Science Handheld Portal Device). The portal gun creates temporary passages through solid surfaces, allowing for creative platforming and multiple possible means of clearing a level. The game also requires the player to solve puzzles at times to clear sections of levels. In addition to point-to-point movement through portals, players can also utilize other means of movement of themselves and various objects. These include: using the momentum of portal movement to make jumps to open positions like ledges; tractor beams; and special propulsion/repulsion gels that can be carried or stored.
