Portal 2 is a great game. The levels were hard enough that I couldn't figure them out straight away, but could still noticed the solution after 5-10 minutes. Games like Modern Warfare 3 couldn't hold a candle.
Portal 2 Walkthrough
Return to Aperture for further testing. Our Portal 2 Walkthrough provides a walkthrough for story mode, tips for co-op, and unlockables.
The Escape
Floor 1
The door ahead will not open fully. You'll need to fire your blue portal through the door and your orange portal to the left. Enter the portal and run along the catwalk. You'll come to an inactive conveyor belt. Run along this machinery and leap to the left across more catwalks. Leap down to the ride the assembly lines and run quickly to avoid being crushed or burned. Turn to the left and run down more catwalks, making sure to jump over the broken floors. Fire the blue portal at the wall at the end, look above to the small room and fire your orange portal. Move through the portals and drop to the next area. Shoot your orange portal across the chasm and your blue portal at any nearby wall. Enter the portals and fire a blue portal at the next wall ahead. Re-enter the orange portal to arrive at the next catwalk. Keep moving forward and you'll arrive at a room with a large spiral tube. Ride this tube down to the door below, leading to the next area.
Floor 2
In the next room place your blue portal on the wall over looking the conveyor belt. Make your orange portal on the wall behind you and enter it to land on the belt. Ride the belt to the other side and run over the ducts to reach the second belt. Ride this one to the next catwalk and follow the path passed the grill. Place your orange portal on the above wall beyond the glass window. Next place your blue portal anywhere nearby and travel to the small room. Place your next orange portal across the hall over the banister. Wait for a defective turret to come to the test area and shoot a blue portal behind its intended target. The defective turrets won't fire, allowing you to slip by unharmed. Enter the next room and meet with Wheatley again. Let him "hack" the door to gain access to the turret control room. Place down your portals to enter the small turret control room and remove the test turret. Return to the catwalk and grab a defective turret as it's flying towards the garbage. Place the defective turret in the control scanner and move to the next area.
Floor 3
Take the lift ahead to reach the top catwalk. Press the button on the right and it will open the door on the left. Before moving on shoot your blue portal at the wall that is being hit with the laser beam. Move through the door and use your orange portal to summon the laser against the moving walls. This laser will be enough to destroy all eight tubes connecting to the toxin. Return to Wheatley to enter the next area.
Floor 4
Place your blue portal on the flashing ceiling off in the distance, while your orange portal may be anywhere nearby. Move into the portals and land in a chasm. Attempt to open the door ahead and the room will reform, dropping you below. After a scene grab Wheatley and place him on the node. Move up the steps and place your blue portal on the white floor. Put your orange portal on either wall of the now open room. Enter the portals and place your blue portal on the opposite wall. Return through the portal to get by the defenses and reach the switch. Press this last button to end the chapter.
