Portal Reloaded: How to End in the Wrong Timeline

This a tutorial on how to end in the wrong Timeline on some of the chambers in Portal Reloaded.

What is this guide?

This guide tries to explain some of the ways you can get a wrong timeline end on different chambers in portal reloaded. A wrong timeline end is where the developer has not inteded for you to finish the chamber when in that timeline. Some unique dialogue is played and you are prompted to go through a time portal to get to the correct timeline.

Chamber 04

You need to get the cube when you are in the future timeline, then put the cube on the stairs so it’s tilted. Bhop on the upper part of the cube (you need to get some weird boost from the cube) and grab the cube right after jumping on it. Then simply land on the elevator, put the cube on the button and you are done.

Chamber 05

For this chamber you need to get the cube when in the future timeline, tilt it using the hole on the plateau. Put the cube in the corner and jump up on the cube, jump up on the plateau and grab the cube. Then just put the cube on the button and you are done.

Chamber 08

To get to the platform in the video, simply put a portal on the tilted surface facing the room with the time portal button in it, put your other portal in the pit and jump through. When you are on the platform (in the future timeline) put your portal on the same two surfaces and jump through, you need to do some strafing to get to the pit and then when you get through the portals you need to hold whichever button you use to get closer to the platform (often A or D). Once up you can just go through the door.

Chamber 10

This chamber is probably the easiest, you just have to put a portal on the ground close to the end platform and one under you, jump through and do some strafing to get to the end platform and you’re done.

Chamber 12

When in the future timeline, you need to do some decent Bhopping while pressing the button when you pass it. Get through the fizzler and shoot a portal under the cube dispenser and one on the portal surface facing you. Catch the cube and put it on the button, and you’re done.

Chamber 13

When in the present timeline, put a portal a bit right of the laser, put your other portal at the far right of the chamber wall and if you’ve done it right the laser will autocorrect to the laser receiver.

Chamber 15

This one is a bit tricky, when in the future timeline you put a portal almost at the highest point of the wall (you don’t want to hit your head on the ceiling). Bhop through and land on the platform to your left. Get the laser cube, put one portal where the laser is and one facing the laser receiver. Make sure the laser receiver is getting the laser, grab the cube and jump through the portal receiving the laser and land up on the chamber sign. Jump down to the edge of the window and then just jump to the end platform, put the cube on the button and you’re done.

Chamber 20

When in the future timeline, stand facing the light bridge and shoot a portal on the wall above you almost at the highest point and to the right. Put your other portal on the wall close to you, bhop through to the left around the corner and land on the camera. It can be a bit tricky to stop on the camera but once you are there simply jump down to the highest elevator and go to the end.

Chamber 21

This one you have to be in the present timeline, you need to have the cube with you on the button and a portal with a horizontal light bridge. Stand on the cube, jump and put the light bridge so it would collide with you and then you will get pushed up onto the light bridge.

Chamber 23

Here you should be in the future timeline, put a portal on the funnel and one on a wall on the bottom row. Crouch fly (crouch fly tutorial on the bottom of this guide) to the cube button and press it, catch the cube and fly up the the big button and put the cube there. Then you’re done.
