In Mutiny, the levels consist of several enemies on different parts of the map. Both the pirates and enemies take turns moving and using weapons against each other until all of one side's units are destroyed. More weapons can be obtained from the treasure chests that fall from the top of the screen. While playing, a map in the upper left hand corner of the screen shows the locations of the player's pirates as well as the enemy units' or player 2's pirates. Player 1's pirates will always appear as red dots on the map, meanwhile player 2's or the CPU's units will display as blue. Treasure chests will appear as yellow dots as well.
