Men in Black 2: The Series is a side-scrolling platform action game. The player chooses to play as either Agent J or Agent K, and must defeat aliens and cloned agents throughout eight levels set in New York City. Both characters play the same and are different only in skin color. The player can use various weapons, including the Noisy Cricket.[5][6][7]
The player's objective in each level is to collect four pairs of Men in Black sunglasses. Five boss enemies are featured in the game. The game offers a cooperative mode in which up to seven other people can take turns playing the game using a single Game Boy Color console. During the cooperative mode, the player is given a total of 40 lives. A four-digit password is given to the player after each level is finished.[5][6][7]
