CREATE CARDS THAT SHOULD NOT EXIST

Blank Battle Cards let you build new cards from scratch, while existing cards can be reshaped around your strategy.

Your cards also LEVEL UP as you use them, so the deck you begin with will not be the deck you finish with.

You are not just collecting cards...

You are creating them.

BUY FROM VENDORS OR KILL THEM

Strange merchants carry battle cards, upgrades, perks, and effects that can completely change your run.

Buy what you need and walk away...

OR kill them and take everything.

It might give you the perfect build, but Grimslair remembers what you do.

You have been warned.

BREAK GRIM'S CHAINS

During battle, enemy cards can connect into deadly chains, allowing multiple attacks and effects to activate in a single turn.

Play cards to build your Chain Breaker, then destroy Grim's connections before the full chain activates.

FIGHT BESIDE YOUR DOG

Your husky fights beside you using its own cards, abilities, upgrades, and strategies.

Build its deck, strengthen its attacks, and turn your companion into one of the deadliest parts of your build.

And yes, you can pet your dog... :)

GIVE SOULS TO GRIM OR BE SELFISH

Every soul can make someone stronger.

Give enough souls to Grim and he will reward you with a powerful new perk.

Keep them instead to gain Essence, unlock Soulwords that modify your cards, and claim their power for yourself.

The soul is yours...

You decide who gets it.

EXPLORE THE WORLD OF GRIMSLAIR

Every run generates new paths, locations, enemies, and opportunities.

Explore graveyards, forests, caves, deserts, frozen mountains, and other dangerous regions as you hunt for battle cards, resources, vendors, and the path toward Grim.

Take the safer route and prepare for what lies ahead, or push deeper into the unknown and risk everything for greater rewards.

TURN BACK TIME

Time is not just moving against you. It is a weapon.

Use Time Warp cards to rewind dangerous moments, undo costly mistakes, and change the course of your run before it is too late.

DO YOU HAVE WHAT IT TAKES TO BECOME THE NEXT GRIM REAPER?

Explore the map.

Build your power.

Reach the edge.

Defeat your father.

Bring Isabella back from the dead.

Claim the title of GRIM REAPER.
