"Grave Slayer" is a highly intense and stationary survival horror game that places players in a graveyard full of aggressive monsters. You play as the only survivor and your direct goal is to simply survive by dispatching the inhuman undead monsters which swarm towards you in waves. The game eliminates any notion of escape with total concentration on joyfully combating monstrous fiends, no matter how grotesque, by performing quick gestures with exact accuracy and timing. The graveyard is cold and dangerous, leaning into the fog, intensifying the atmosphere as more and more grotesque foes draw closer. Each and every swipe, tap, and slash must be meticulous to stave off the ellipses of monsters attempting to overrun you. It is not a nightmare you'll escape; it is, rather, a superb test of endurance as you simply aim to stay alive for as long as you're able while continuing to break your record each time you play. Grave Slayer, in its essence, offered a distraction experience fueled by frenzied adrenaline, but few other horror experiences pare back and begin invoking what horror truly inherent rush scratch—fear, survival, pure thrill of kill. The game doesn't offer a narratively defined ending or haven, but how long can you thrive in a world suggesting that the only way out?
