What is UNKILLED - Zombie Online FPS?

UNKILLED is a high-fidelity zombie FPS that blends solo story missions with competitive PvP and an asynchronous base-defense mode called Skirmish Ops. It is positioned as a premium visual experience on mobile, utilizing an intuitive autofire control scheme to attract a wide range of shooter fans. However, the app is currently facing a decline in user sentiment due to persistent multiplayer outages and aggressive, poorly-filtered advertising, which threatens its long-term retention despite its strong graphical foundation.
