Hello everyone ! I'm a french casual player and I remembered a few days ago of DeadCore. I'm very motivated by speedrunning it and hopefully get a sub 25min ! I don't know if anyone will ever answer me lol but I'd like to know how to "restart" the game. I mean, for a NMG run, you have to start a run without any powerups, which i'm not able to. Thanks :)

You can't change from NG+ to NG in the game, you have to do it through the files.

Go to resources and imawakka's "external save file resetter" will make it so you can restart the game easily. Download it, find your save file (Steam>steamapps>common>DeadCore>long slew of numbers) and put it in the directory, then you can use the resetter.

If you don't want to use the resource, just go to the same directory, and delete story.save before every time you start the game.
