I played this in the definitive version and didn't even realise it was a DLC tomb. It was actually the very first one in the game... It's fine, it's a short 5 or so minute puzzle involving a plane. Doesn't stand out from the other optional tombs I've done.

I don't understand why they had dlc that adds ONE extra tomb that doesn't even give you anything cool (just more xp and scrap). The tomb itself isn't really cool, and its extremely bugged. Just weird.
