Tinge of Terror is an update for Grime that add's NG+ cycles. Instead of just inflating numbers however, this mode also empowers enemies with new properties. Either their attacks will have more going on, or the enemy itself will have some new facet to it. Most bosses also have empowered attacks (or even new phases!).

YOU ALSO get to keep all your Metroidvania abilities upon restarting, you pretty much keep everything except like 1 or 2 items. You can't get dupes of weapons or clothes, so all those pick ups have been changed into weapon upgrade materials if you wish to literally upgrade all your weapons. Bosses now drop materials that either push your weapons past the previous max level, or your absorbed enemy perks past theirs.

There is also an exclusive boss to this.

Grime still rules.
