| The portal conventions
within this walkthrough are: Blue portal = Enter | Red portal = Exit This helps simplifying the description. Of course you are free to shoot your portals the way you like it best. |
01 / The Infinity Rooms 1
Out of nowhere, you are here, all of a sudden. These are the prototype rooms of The Infinity Project. Look around, and all you see is yourself, respective Chell, your player character. Walk around and watch yourself doing so, over and over again. The rooms never end, no matter wich direction you are turning to. To give you a minimum of orientation, the far end walls of all four cardinal directions have different colors. If you plan to try reaching a far end wall, abandon all hope: this is The Infinity Project, you will never succeed.
To proceed, all you have to do is to walk around from room to room long enough. Take turns, also walk through the room's corners and after a while large trapdoors open in the middle of all rooms. If you are looking for a shortcut: Go to the next room, turn right or left, go to the next room, pass all four courners in it. This will do the trick.
02 / The Infinity Rooms 2
After you have dropped to the floor, look out for the portal gun lying around somwhere near you and grab it. At first glance, these rooms look al lot like the first verion, but there is a different infinity technology working here. You will find out as soon as you try to reach the far end wall. This time you will be able to do so, but passing through them takes you to where you came from. To proceed, look for the four small switches marked with a shining "X" hidden in the four rooms adjacent to the center room. A general hint: look up! Use the portal gun to reach the upper pilars and push all four buttons. Orientation: Each room where you have pushed the button will be marked with a vertical spotlight in front of the far end wall. After having pushed all four buttons, go back to the center room, where another trapdoor leads you to the next room.
03 / The Infinity Rooms 3
This is the advanced version of the prototype. Walk around until you see a button marked with a shining "x" in one of the columns. Pushing it lifts the teleporters through the floor in every room. Step through it to enter the gravitiy research department.
04 / The Gravity Room 1
Stepping through the teleporter adjusts your protection suit to gravitiy status 180° W. Accordingly, you will be landing on the ceiling of the room, looking up at the floor. Heed the No-Panic-advice on the wall and look out for the wooden cupboard standing against one of the walls, bearing a red button on its top. Push the button and watch two additional pilars rising from the ceiling against the opposite wall. Jump up, open the door and jump to the next room.
05 / The Gravity Room 2
This is the technical center of the Gravitiy Research Unit. Turn left and approach a button raising from the floor above. Turn around and push the button. As your gravitiy status is 180° W, while the room itself is set to standard gravitation, you see the cube falling upwards from the cube dropper to the floor button placed on the floor above. This opens the door to the catapult. Approach the catapult, turn arount with the catapult exactly behind you and shoot a blue portal at the lower section of the opposite wall. Turn left and shoot a red portal to the lower, sloped section of the wall oposite the large red button on the uppere section of the opposite wall (right of you while lookiing into the room).
Of course, it is of no importance how you touch the catapult. But if you want to see where this will take you, turn your back at the catapult again and step back. This throws you through the portals at the red button, which turns on the teleporter, sitting on the floor above in the middle of the room.
Shoot a red portal to the upper section of the wall opposite the teleporter's passage, next to the portal you have just shot before (but this time at the wall's upper section). Like before, step back against the catapult and watch yourself being transported to the next garvity section.
06 / The Infinity Rooms 3 - Gravitation status: 90° N
If you get the impression to have returned to a well known area you never have seen before, don't be surprised. You have returned to The Infinity Rooms 3, but your protection suit has been set to gravitiy status 90° N. In other words: You are standing on one of the walls of the rooms. Where you could walk endlessly before, you will fall to your death now. Yet you will have to face the danger to proceed.
Turn right and walk up to the wall's edge (opposite the Panic advice on the far end wall). There, far below, you see a circular target mark on one of the pilars. Maybe you will have to zoom in to discover it. You wll have to jump on the pilar to push the button placed next to the target mark. Maybe you will need a few tries until you succeed. Rescue advice: If you miss your target, you do not need inevitably fall into the abyss. Just keep on walking forward while you fall - this lands you on a saving wall in most cases.
After you have pushed your first button, walk to another observation point opposite the first one. This time, you walk up to the wall's edge with the Panic advice in jour back. On the right, you see another target mark next to the large ceiling light. Jump down at it (with a stopover on the long pilar) and push the second button. This turns on a white upward spotlight on the right side of the long wall's edge.
There are two buttons in the colums left and right of the long wall's edge. You have to push them both within three seconds, and you're done. This turns on the second white spot on the left side, together with the garvitation bridge crossing the infinity abyss.
While crossing the gravitation bridge, you may want to stop in the middle and look down. The sight is worth seeing, believe me. Proceed, and enter the sluice to the GCC.
07 / The Gravitation Control Center
This is the place where the gravitation status of your protection suit (and the suits of the other test subjects) is set. You will notice that the room is fit to be entered with any active gravity status. There is not much you can do here. After a minute, the gravitation system comes into operation, lifting you into the neutral zone and restoring standard gravitation for your protection suit. After a short while you will be transported back to where you came from.
08 / The Infinity Rooms 3 - Standard gravitation
While you are able again to permanantly touch the floor of The Infinity Rooms 3, you have successully passed The Infinity Project. Jump through the trapdoor and breathe easily.
You did well, test subject.
