About this game
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.
