In Nightmare Birthday Party, your big day takes a turn no amount of cake could fix. One moment, you’re waiting for guests and gifts—the next, you’re dodging flickering lights, creepy whispers, and... whatever that thing is lurking near the punch bowl.

What should have been a simple celebration becomes a wild first-person horror comedy where survival is the real party game. Navigate a retro-styled house filled with bizarre surprises, unexpected scares, and just enough absurdity to make you laugh (nervously) between screams.

Alone, unprepared, and maybe a little overdressed, it’s up to you to outwit whatever’s crashing your party. Blow out the candles, make a wish, and try not to get caught—because in Nightmare Birthday Party, the fun is just getting started.
