About This Game

No basic attacks. Every strike is a card.

Peak Slayer is a turn-based roguelike deckbuilder played on a grid. Taking a step and playing a card each cost a turn, and enemies act on the same clock. Climb a tower that is generated anew every run, and win each fight with the right card from the right tile.

Your Cards Are Your Weapons

Attacks, movement and defense are all cards. Each of 100+ cards has its own shape and range, so where you stand and which way you aim matters. Click a card, then click it again to auto-aim.

Positional Combat

Slam enemies into walls, knock them into pits, hide in tall grass. Ambush a sleeping enemy for double damage. Strong enemy attacks are telegraphed one turn ahead.

Six Elements and Terrain

Fire, Water, Nature, Poison, Lightning and Dark. Fire burns grass, soaked enemies freeze, and lightning spreads through water. Monsters and bosses have elements and weaknesses too.

Bosses That Fight Back

Every act ends with a boss of its own: webs from the ceiling, charging warlords, poison clouds and second phases. Read the tell, find the opening and finish it with your best combo.

Builds Shaped by Relics and Fusion

Earn new cards as you clear rooms. 60+ relics change how your cards work, earned from bosses and treasure rooms. From the middle of the tower, fuse two cards in your hand into one powerful fusion card.

A Different Tower Every Time

Six acts, each with its own monsters, terrain and boss. Shops, campfires, secret rooms, sealed rooms and a face-down card gamble — every floor is generated fresh each run.

How to Play

Step into a room and the doors lock as the fight begins. Read your hand and your enemies' next moves, then move or play a card. Clear the room to earn cards, keys and treasure, and push on to the next one. Fall, and you start over — climb again with a new deck and new relics.
