Minecraft Infected (MCI) is a unique server for Minecraft that takes inspiration from the popular Infected mode in Call of Duty. In this game mode, players are given a brief period of one minute at the start to find a hiding place before a virus begins to spread, converting some players into zombies. The objective for the zombies is to eliminate all human players by "infecting" them, while the humans must do their best to survive until the timer runs out. If the zombies manage to infect every human before time is up, they claim victory; however, if any humans remain uninfected, they win the game.
As players engage in the Minecraft Infected experience, they have the opportunity to earn cookies, which serve as a form of currency within the game. These cookies allow players to level up and unlock better gear, which can enhance their chances of survival against the zombies. The thrill of the game lies in the tense atmosphere of hiding and survival, coupled with the strategic elements of determining when and where to move in order to escape the impending threat of the infected players.
