About this game

—Enter the Swamp

Multiple goals. Multiple routes. Multiple endings.

Complete Orders (missions) to unlock new paths in a branching stage layout.

As soon as you dip your toes in, you'll find yourself sucked deeper and deeper into this bottomless quagmire of a shmup.

100 stages. Over 1,000 Orders.

Get lost in a hundred-stage maze, carving out your own path to the goal.

Complete over a thousand Orders to expand branching routes and unlock new stages.

Push beyond the depths to reach the true ending.

Double the fun with twin-stick action.

Your machine is equipped with a devastating weapon: the "Dolls."

Detach them from your ship and aim them freely to unleash precise, powerful attacks.

You also have a variety of unique special attacks along with the Megalophaz, a high-damage bomb.

Unravel the mystery of disappearing players.

Lusie spends her days shut in her room, playing her favorite online game.

One day, rumors begin to spread about players disappearing—both online and in real life.

To make matters worse, her partner AI called Cheep'O develops a malfunction that corrupts her linguistic programming.

As they search for answers, Lusie and Cheep'O find themselves drawn closer to a hidden conspiracy, one lurking beneath the game... and the real world, too.
