Hey, Unless I still dont get how to do it correctly, the Rocket Clip seems to be patched out in the PS4 version. I tried it many times in many rooms, but never got it (not even randomly). Is there someone who was able to do it?

I'm going to guess it's execution error on your part. I have not heard anything about an updated version of the game although the PS4 version was the latest to come out so it could be possible. I have no way of testing this for sure however.

It is possible on PS4. I did it in my run in multiple areas. If my run were to be verified, you'd be able to see it, but from my experience, it is very easy and possible on PS4.
