CO-OP BULLET HEAVEN WITH A LIVE GRIMOIRE MASTER

Grimoire of Monsters is a co-op action roguelike for 1–4 players. Most of you fight to survive. One of you is the reason it's hard.

Team up with friends and fight through huge waves of enemies. Pick up new spells, build powerful combos, revive each other, and take down giant bosses. Or play as the Grimoire Master and become the threat: send in monsters, twist the battlefield, take control of bosses, and ruin every plan the party has.

Every run is a fight between the team's spell combos and the chaos the Grimoire Master throws back at them.

SURVIVE AS THE PARTY

Every run is a race to build something powerful before the monsters catch up.

• Pick from a roster of heroes with different playstyles

• Combine spells and upgrades into powerful builds

• Revive your friends when they go down

• Push through tough enemies and boss fights to win the run

BECOME THE GRIMOIRE MASTER

You do not fight the monsters. You are the monsters.

• Send in waves of enemies

• Place hazards and twist parts of the battlefield

• Block the party's view and split them apart

• Take direct control of bosses during key moments

The Grimoire Master decides when things calm down, when they get scary, and when the party has a really bad day. Every run feels different depending on who is playing this role.
