Wait, no, actually, make it impossible to shoot while the box is over you... but you can still see them.
Like Od Notor's propane tank, can only be used in zombie minigames, only the other way around.
Also, it'd be cool if there was a teleport function to where ever you're pointing, replacing your minifig with a bot that lasts for 1 minute.
That's just what I'd think.
