Battletoads/Double Dragon is a beat 'em up video game where the players, as either one of the three Battletoads or Jimmy and Billy, attack enemies, swing ropes, go on spaceships, and turbo bike to defeat the Shadow Boss and Dark Queen.[12] It has three play modes: a single-player, a "2 Players A" mode where the players can hit each other, and a "2 Players B" that doesn't have that.[13] Its engine and gameplay is from the original Battletoads,[14] and less like Double Dragon.[15] Like the prior Battletoads installment, there are only three continues and no password system,[16] and in the two-player modes, if one player loses all lives, both players have to start a level over.[17] The 16-bit versions have identical gameplay to their NES counterparts, attacks and jumping are triggered by only two buttons.[18]
