In a glance, this game looks to be very hard. In a traditional beat ’em up style of game, you have at your arsenal a punch, a kick and a block in addition to your basic movements such as left, right, duck and jump.
It’s difficult, until you discover the secret moves that make game play so much easier. A roll can be executed by pressing z, x, z, x and a torpedo dive can be executed by pressing x, z, x, z. Note that these moves cannot be keyed in quickly and the player should wait for the move to finish before pressing the next key.
