Wheres the Moon cache that it unlocks with the crystal?

Have no idea where it's located and didn't find any video showing it.

After the first enemy room, there's a side room in the laser hallway with a Heal Bot inside. That's the cache

Ok, thanks for the answer.
From the description i assumed it would be a secret room with a bunch of guns.

That's what my friend and I thought too, but nope, just an extra heal bot. It didn't help that our first time on the Moon was after getting that power crystal so we thought that room was always open.
