rplus_unlockhearts: unlocks all Tainted hearts (this is especially useful, because once you unlock a tainted character, you won't be able to get this achievement legitimately, because it triggers when you touch tainted character entity in a closet on the Home floor (if you want to unlock hearts one by one, you can summon the entity yourself by using console command spawn 6.14 while playing as a respective non-tainted character)).
rplus_reset: resets your achievements and unlocks progress.If you, however, don't want to achieve the marks legitimately, you can use the unlocks menus provided by Mod Config Menu mod or Dead Sea Scrolls embedded library, or use certain console commands (to open debug console, press ~ ('tilde') key): This mod initially was aimed at encouraging players to play all tainted characters once again, giving a fresh experience and perspective and awarding them with new items, trinkets and other types of unlockables. Note that they do not work retroactively, meaning that if you already have a certain completion mark, its respective content won't automatically be unlocked. Since mod version 1.27, achievements are in the mod!
