Oh god, noooooooo. So much hard work gone to waste! Unless you can somehow keep your save file?

So sorry for your loss, man. Such an awesome game.

should have bought digital /s

Discs? People still use those?

That's bizarre! I have no idea why that would happen with a clean disc.

For example the nintendo gamecube is very picky about discs, had to adjust the potentiometer of the laser, Nintendo sets it always to have very weak laser beam to extend laser lens life. If the disc is very good condition, this might be the problem, check if you can send it for repair in warranty.

Yeah my save file should be OK cost I guess on hard drive. Just all that time invested 43 hours and now I cant complete :(

Wii u and the disc out off warranty so no good. But every other game I have work fine including older games so it must be disc either way I'm annoyed

might sound obvious, but have you tried the disc on another WiiU? (with your save?)

Yeah, sorry, very fun game. Have you lifted up the big head yet and gone spelunking?

Jump that digital bandwagon.
