Mantis Games released their first major update to Deck of Haunts on June 13th, with the chilling new “Nightmare” chapter challenging players to their toughest trials yet. The update features an all-new Nightmare Mode, a Trap Starter Deck, new cards, traits, and a raised level cap.
Nightmare Mode
Nightmare Mode challenges you to survive 13 sequential Nightmares, each composed of 13 cursed nights. Every Nightmare throws new curveballs your way: curated groups of humans with unique traits, and escalating modifiers that carry over from one Nightmare to the next.
Every kill or madness you induce in this mode earns you souls. By collecting 13 souls, you can summon the Grim Reaper himself to harvest a human of your choice instantly. Survive all 13 Nightmares and you’ll unlock the Crypt Room, letting the Reaper haunt with you in other game modes.

Nightmare unlockables include Corpse Explosion (card), the Crypt Room, Sleep Paralysis (card), and a new achievement.
New Trap Starter Deck
Once you reach XP-level 12, you’ll unlock a new starter deck built entirely around traps. These cards specialize in ambushes, synergy, and indirect terror, giving you new strategies to exploit adventurers who get a little too confident.
Combined with existing mechanics, traps offer new ways to sow fear and chaos, one carefully laid mechanism at a time.
More Deadly Details
This update also comes with several tweaks and polish including heart death animation, dead human portraits removed, and a counter of turns on humans with the “Helpline” trait.
