Lemmings 2 is divided between a series of twelve worlds, each containing ten levels of obstacles, traps and other hazards, where the goal of each level is to guide a group of lemmings from their entry point to an exit(s) in the level within a set time limit, by creating a safe passage using a variety of skills. Unlike its predecessor, the player is only required to get at least one lemming to the exit of each level from the sixty they begin each world with, but the amount saved affects the medal ranking they receive - Gold being the best result, down to Silver and then Bronze for the lowest amount rescued. In addition, the number saved in one level becomes the starting amount in the next level; as some levels may require several lemmings to complete, the player might have to replay an earlier level to save more lemmings for the following ones if they realize they do not have enough.
