Players must carefully manage ammunition for their firearms and use melee attacks to conserve supplies.

Parasite in City is a 2D side-scrolling survival horror game originally released in 2013. While it was not initially developed for mobile, "Parasite in City Apk" refers to various fan-made ports or emulated versions that allow the game to run on Android devices.

Unlike typical zombie games, the parasites in this game retain some intelligence. They set traps, communicate through guttural sounds, and actively hunt any uninfected survivor.
