Every year, on the last night of October, the dead of Hollowmere climb out of their graves and go looking for the living. The town's answer has always been the same: hire a keeper, lock the gates, and pray they're still standing at dawn. This year the keeper is you. Dawn is eight minutes away. Your weapons swing on their own - your whole job is where you stand. Stay close enough to hit, far enough to live. Blue gems fill the bar, the bar levels you up, and every level hands you a card: a new weapon, or another rank on one you already carry. Coins open the locked gates, and the gates open new ground - deeper graveyard, worse dead, better loot. One gate leads out. Ten keepers to unlock, each starting with a different weapon. Three difficulties. Hold the graveyard till 6 AM, or buy your way to the Iron Gate and run.
