"서울 좀비: 용병 키우기" is a modernized SF fantasy game with a touch of imagination. Players can equip themselves with melee weapons, psychic staffs, and three types of guns to prepare for battles tailored to their preferences. The game combines bullet-hell dodging mechanics with hack-and-slash elements, allowing manual combat control in challenging situations or convenient auto-hunting against overwhelming foes.

Embark on a journey through a world expanding from Seoul, featuring real locations such as Gwanghwamun, City Hall, and Dongmyo, adding a unique K-game identity. With around 300 parts-based items and skins including weapons, hats, tops, bottoms, and shoes, players can customize their characters extensively. Engage in online interactions through chat, meeting other players in villages, and participate in ranking systems to measure progress and combat prowess.
