About

Roach Outbreak

Features
Read full description

Your phone has been infested. “Roach Outbreak” is an unconventional idle simulation game where you feed, hydrate, raise, and breed a colony hiding deep inside a dark crevice. What begins as a tiny colony soon grows out of control. Egg cases appear, nymphs hatch, and roaches multiply until the entire room is crawling. Disgusting. Yet impossible to look away. Before long, you may even find a favorite. 【RAISE AND MULTIPLY】 Leave food and water for your colony. Watch each roach eat, move, grow, and reproduce. How large can your infestation become? 【SHINE A LIGHT】 Point a light at the colony and watch them scatter in every direction. It is horrifyingly satisfying. 【CHOOSE YOUR FAVORITE】 Name one special roach and track its size, growth, meals, and survival time throughout its life. 【COLLECT RARE ROACHES】 Discover Jet Black, Red Copper, Silver Back, Albino, Oil Slick, and the legendary Golden roach. Hatch special egg cases and complete your collection. 【BUILD YOUR OWN HIDEOUT】 Arrange scraps of paper, old receipts, empty boxes, and other hiding places. Unlock unsettling locations such as beneath the refrigerator, behind the kitchen shelf, and beside the tatami. 【RECORD YOUR OUTBREAK】 Track your largest colony, biggest roach, longest survivor, and fastest specimen. Capture your infested room and share it as an image. You hate them, but you cannot stop watching. You fear them, but you keep raising them. Begin your forbidden outbreak today.
