This was a while back, but I thought I'd bring it up.
These videos from Nintendo and GameXplain do a good enough job of describing it.
It looks and sounds cool in all honesty, but it seems a little bare bones, and the costumes could've been a lot better (the Goron looks like a cheap Halloween costume). I was hoping it was more like a traditional escape room but with Zelda characters and enemies. Something like "Find the key to escape or Ganon strikes you down.".
What do you guys make of Defenders of the Triforce?
