Gravemark, a dark fantasy hack-and-slash game played holding the phone vertically with one hand, has launched on Google Play. It became available on October 15, 2026 in Japan and on October 19, 2026 worldwide. The game is built around a single split-second call: go down one more floor, or turn back here.
Nothing Is Yours Until You Bring It Home
In Gravemark, the deeper you dive, the better the items that drop. However, anything you pick up does not belong to you until you carry it back to town.
If you die, you lose the contents of your bag, the gold collected during that run, and any gear you equipped during the run. Gear you equipped in town before heading out, along with the contents of your storage, stays with you.
Combat Is Automatic, the Decisions Are Yours
Attacks proceed automatically, and the only things the player touches are skills and potions. Whether to drink a potion, whether to dive another floor, and what to pack into the bag to take home are all up to the player.
Each floor offers two paths, which lead to an enemy, a spring, or, on rare occasions, a grave marker. The path card shows how much damage a single hit from that enemy would deal, so players choose a path based on their remaining HP.
What to Pack in the Bag, and What Turns Up in Town
Time stops each time an enemy is defeated. Players then decide what to pack into a grid-based bag to take back with them.
Items brought home stay unidentified until they are appraised in town. Above even Legendary items are the Relics, 15 one-of-a-kind pieces that each have their own name and artwork. Every one of them comes with a price to pay.
