lol stop breaking my map xD The thing is Im no into Portal 2 anymore so I wont fix it anytime soon :S
But nice that you could break the map :)

On second thought. That won't prevent my solution. The acid pit must be wider. I can simply fling the cube over the acid pit.

Simply making the fizzler viertical instead of horizontal at that faith plate will prevent my solution.

How do I make a video of it?

Put a portal above the faith plate opposite the laser. Take the cube through holding it high to avoid the fizzler. While in the air, fling it toward the exit. Then put a portal above the entrance door and place one on the floor in view of the panel above the faith plate. Start falling between portals. Place a portal above the faith plate and it will fling you to the exit landing.

you sure? tell me how please

lol

This can be done without the coop cube. You only need the reflection cube. And the laser is unnecesary.

interesting, I tested it many times and had no problems. Watch the video, maybe you made it too hard for yourself. Thanks for playing!

A novel idea, although the execution was a bit tricky. In particular the cube was prone to bouncing into the goo.

Not bad. But I was too impatient to try the actual coop cube part till I got it to work.

but u can quicksave, I made goo, because when I make it deeper it looks ugly

Nice concept here, but more problems than your first map (Tension). You are able to bypass the laser relays entirely by getting to the top and jumping through a portal to fly up to the cube, but the biggest problem is the goo. With no autosaves, the puzzle has to be done again and again if the cube knocks you off course. The solution is simple: make the pit deeper and give it no goo and a portal panel on the side so you can escape.
