Puzzle on gm_excess_island

Does anyone know how to do the puzzle on gm_excess island? I have found a portal and an artifact cube thing. I have managed to open the portal by breaking the checker (giving it a bad code) to open the portal into a circular island but thats it. I would like to know what to do with the artifact/cube thing.

You should’ve posted this in the excess_island thread.

I searched for ages, but I couldn’t find it.

It’s in the no. 11 in the releases section…how can you not find it?

hell I can’t find it

Maybe it’s because garry has deleted the releases section?

If you’re too lazy to use search.
