Murder Mystery/Descent Into Madness

The Descent Into Madness is a progression system for Murder Mystery that teaches players about the game's core mechanics using challenges and objectives. Each core mode (Classic / Double Up!, Infection, and Assassins) has its own Descent.
Players can only make progress on unlocked challenges, and when they complete one, players earn Murder Mystery tokens or cosmetics and unlock the next challenge(s) following it. The item will be enchanted when the player has not claimed their reward yet,
Completing a challenge:
