I'm a little unsure if I'm posting this in the right place...
How can you make a weapon usable (visable, selectable) in one level, and unusable(invisible, unselectable) in the next?

When the level changes, simply take the weapon away from the player. There are several ways you could do this. I prefer using a script where I can use the SetAttribute command to take the weapon attribute away from the player.ini file. I am pretty sure you could do this with an entity, but I don't have much experience with entities, since I usually just replace them with scripts.

Just have a script attached to an "invisible" actor in the desired level like so:

Spawn{() (or whatever)
weapon# = false

and to switch back, change to true
