Set in the year 2000, Zomborg casts players as mercenaries sent into a sealed infection zone after a medical team is killed and its research is left behind. The United Nations wants the team to recover that data and uncover the outbreak’s origin, with the possibility of a cure driving the mission. The premise frames the danger as both a rescue of vital research and an investigation into the infected dead.
The game pairs character customization with a choice of AI teammate, letting players select a companion to suit their strategy. Combat draws on ten weapon types, which can be bought with money earned during play. Its battlefield scale is part of the design: the store description says as many as 100 zombies can appear on one screen, setting up encounters against dense groups rather than isolated threats.
Zomborg is categorized as single-player, so its player-count context is a solo action-adventure strategy game with an AI partner, not a shared multiplayer session. The combination of purchasable weapons, teammate selection, and large on-screen zombie crowds gives its combat a tactical angle within the bleak quarantine-zone premise.
