This is a 2D shooting survivor game.
In a dark underground disco full of zombies, earn money, strengthen your character, and survive until the time limit.
Earn money to survive
When you defeat a zombie, it will drop money. You can use the money in the shop, which is periodically opened, to strengthen your weapons and characters, making it easier to progress through the battles.

Use the money you've earned to strengthen your characters
You can strengthen your characters depending on your score at the end of the game. Even if you can't clear the game in one playthrough, keep trying and aim to clear it.

Get into the rhythm and advance through the game to your advantage
There is always music playing in the disco, and by pressing the buttons in time to the rhythm, you can fill up the Ult gauge. When it is filled up to MAX, you can use a powerful Ult.

Use whatever you can!
When you defeat a zombie, it may drop items other than money. Use items to make the game more advantageous.
