This game is a 2D shooting survivor game.

In a dark, zombie-infested underground disco, earn money, power up your character, and survive until the time limit.

Earn money to survive

When you defeat zombies, they drop money. By using this money in the shop that opens periodically, you can enhance the weapons and characters you own, giving you a greater advantage in battle.

Use the money you've earned to power up your character

You can upgrade your character based on your score at the end of the game. Even if you can't clear it in a single play, keep challenging it until you succeed.

Ride the rhythm to gain an advantage in the game

Music is always playing in the disco, and by pressing buttons in time with the rhythm, you can fill your Ult gauge. Once it's full, you can unleash a powerful Ult.

Use anything at your disposal

When you defeat zombies, they may also drop items other than money. Use these items to further improve your chances in the game.
