The battle for the right of human habitation against the "Gs" that have suddenly appeared on the earth is about to begin.

You are about the same size as a cockroach, and you must use every means at your disposal to destroy the massive number of "Gs" that crawl on the ground, on the walls, and even fall from the ceiling.
Sometimes you assassinate them with guns, sometimes you blast them with bazookas. Sometimes you use lasers to reap them, sometimes you use missiles to bomb them. Don't forget the pesticides.

Complete all missions by manipulating a wide variety of weapons.

The fate of Japanese houses is in your hands.

First, you have to mess around with weapons!

The weapons you get from Gachagacha are random and their status is also random!
However, the more expensive gachagachas are more likely to produce stronger weapons, and weapons with stronger stats!

Equip your weapons!

Choose and equip four weapons from a wide variety of weapons!
Choose the weapon that best suits your combination and mission!

Go out!

Each mission has five difficulty levels, and the higher the difficulty, the stronger the enemies will be!
A large number of cockroaches welcome you!
