We go on more excursions via tunnels and Alan shields us from turrets with vertical light bridges. __________Director__________ YouTube: http://goo.gl/EywSA Twitter: http://goo.gl/GMF6e Facebook: http://goo.gl/exkPa __________________________ ► Portal 2 ▼ Like its predecessor, Portal 2 primarily comprises a series of puzzles that must be solved by teleporting the player's character and simple objects using the "portal gun", a device that can create inter-spatial portals between two flat planes. The game's physics allow momentum to be retained through these portals, which must be used creatively to maneuver through the game's challenges. The sequel added new features, including tractor beams, laser redirection, bridges made of light, and paint-like gels that impart special properties to surfaces. Portal 2 also includes a two-player co-operative mode, in which the robotic player-characters Atlas and P-Body are each given a portal gun and are required to work together to solve test chambers specifically designed to require cooperation.
