Another easy one we thought. Due to a bug in Portal, if you place a portal in the white tile next to the cube button you can pass the cube through the grating and onto the button. We also did it using the tractor beams though :) Then it was just a couple of awkward jumps around the rail platforms and we were soon out!

No problem thanks

Hey i just fixed it! Thanks alot for the heads up!
Please try out "Ridge racer 15" i believe that is the most fun map i have created!
Thanks alot!

Hey me and my friend are from the Portal 2 Public Critique Page in the discussions. I'm sorry but we could not pass this. We believe something is bugged with the lightbridge. The portalable surface at the beggining of the lightbridge is unportable. The lightbridge makes it impossibe to place a portal there. Could you please fix this so we don't have to rate your map badly? Here is our page so you can message me with a working version of the map: http://steamcommunity.com/app/620/discussions/0/846957366784202644/
