The Blood of Dawnwalker, a dark fantasy vampire role-playing game due in September, will let players trade enemies’ teeth to supernatural creatures in exchange for ways to alter its time limit. The feature matters because the game centres on rescuing the protagonist’s abducted family within 30 days and nights, although time only advances during certain decision-making moments.

The tooth traders, called Sanzhana, are moth-like beings that collect enamel from corpses and barter with unsavoury characters. Creative director Mateusz Tomaszkiewicz said their time-bending abilities are intended to create exceptions to the game’s systems and encourage unexpected discoveries, but the exact effects and limits of trading teeth have not yet been explained.
