June 13, 2025 - Mantis Games is thrilled (and a little terrified) to announce the first major update to Deck of Haunts, launching Friday, June 13th, 2025, on Steam. Titled “Nightmares and Scythes” (v1.10), this chilling new chapter introduces the most challenging content yet, headlined by the all-new Nightmare Mode, a deadly dance with the Grim Reaper, a Trap Starter Deck, new cards, traits, and a raised level cap.
It’s been one month since players began their haunting spree, and now it’s time to prove their skills in the domain of death itself.

Highlights of the Friday the 13th Update (v1.10):
- New Game Mode: Nightmare
- The Grim Reaper & Crypt Room
- New Trap Starter Deck
- New Cards & Traits
- New Achievement
- Level Cap Raised to 12
- “Jason” added to human name pool
Nightmare Mode: 13 Layers of Terror
This isn’t just a harder difficulty, it’s a new game mode built to torment the bold.
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. It’s a brutal, escalating gauntlet of strategic horror.
And then… there’s the Grim Reaper.
In Nightmare Mode, every kill or madness you induce earns you souls. Collect 13 souls, and you can summon the Reaper 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 future/other game modes.
Nightmare unlockables include Corpse Explosion (card), the Crypt Room, Sleep Paralysis (card), and a new achievement.

New Trap Starter Deck
Time to get crafty and cruel.
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.
New Trap Cards:
- Leaking Rust
- Improvised Snare
- Collective Toll
- Amplify Agony
- Dragged Under
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.
And yes, “Jason” is now officially in the name pool for humans. Happy Friday the 13th.
(You can also add custom names in the settings menu, a little easter egg if you want to haunt your enemies, or friends!)
Deck of Haunts: Nightmares and Scythes (v1.10) will be live on June 13, 2025, on Steam. And for the first time ever, Deck of Haunts will be discounted at 20% off during June 13-16, a killer deal to celebrate Death himself.
