    Chapter 3 - Chamber 10

    Learn the level by doing it a few times at a regular pace, then try and follow the video as best as you can, and you should have no problem getting this achievements in a few tries. Can easily be done with 5 seconds to spare.

    The timer begins when you exit the elevator, and stops once the cube touches the pad, unlocking the achievement if done quickly enough.

    Note: With the new update, you can get this achievement in Challenge Mode on "The Return: Ricochet"

    boldfoxrdJust got it. I wondered if pausing affected it but it doesn't. My mistake was most likely waiting by the elevator at the start of the level.

    SashamorningIf this is actually 70 seconds, this most definitely does NOT start when the elevator opens, but when you enter the room. Even on the Rooster Teeth video, they left the elevator at 0:12, entered the room at 0:19, and hit the pad at 1:28. If it was the elevator, that would be 77 seconds. It has to be entering the room.

    I got mine 68 seconds after I entered the room, and it takes 7 seconds to get there, so that would be 75 seconds...over time.

    I did it a bit differently. My run was hardly perfect, but I think the method is a bit quicker. One issue is that the discouragement redirection cube sometimes falls down after it's launched. That's why I paused and waited to see what it does.

    Sorry about the sound. I'm not sure what happened.

    KillipoI forgot to add that this was a great method. :) I prefer shortcuts over speed, so I didn't even bother trying the other methods when I saw this one.

    SighKo666Thanks for this method. Worked for me. I could not get it using the other method.

    BillservoWorked for me on my 5th try or so in the Ricochet challenge level, of course this is after not having played the game for a few months. There are two easy placs to screw up: shooting the blue shortcut portal (make sure the orange one you peek out of turns blue signaling you're out far enough before you shoot) and the drop for the deflecting cube (it sometimes does not land on the ledge and you need to carry it up). I also saw some glitchy behavior picking up the weighted cube.

    In Challenge Mode, Chapter 3: Test Chamber 10 is The Return: Ricochet. You can't make intermediate saves in Challenge Mode, but you can get right to it without having to do Test Chamber 9.
