Roach Invasion

Roach Invasion puts you at cockroach size in a fight to defend human habitation from the “Gs” that have appeared on Earth. They crawl along the ground and walls, and fall from the ceiling. Complete missions by using a variety of weapons to destroy them; the fate of Japanese houses is in your hands.

Weapons and equipment

You can obtain weapons from Gachagacha, with both the weapon and its stats chosen at random. More expensive Gachagacha are more likely to produce stronger weapons with better stats. Choose and equip four weapons from the available selection, matching your combination to each mission. Your arsenal includes guns, bazookas, lasers, missiles and pesticides.

Missions and difficulty

Each mission has five difficulty levels. Higher difficulties bring stronger enemies, including large numbers of cockroaches.
