The Zombie Plague mod is a custom modification for Counter Strike 16, which transforms the traditional multiplayer gameplay into a thrilling zombie-infested experience. In this mod, players are divided into two teams: humans and zombies. The humans must survive against the hordes of zombies, while the zombies aim to infect and eliminate the human players. The mod adds a new layer of excitement, strategy, and teamwork to the classic game.
