Warnings Active: None

The first Testchamber presents you with a static orange portal and a shifting blue portal. Look through the orange portal to see your destination. What is required is to bring the cube out of its room into the room with the button. Going through the blue portals will always bring you back to the center room, but try to move quickly so that you can complete the Testchamber with the least amount of waiting possible. The order should be as such (based on what you can see through the portal): Room with cube, room with button, room with exit door. Also be careful about carrying the cube, as it may become knocked out of your grasp if you try to enter the portal at an odd angle. Go through the elevator to the next Testchamber.
