Mat Mania Taito 1985 Videogame Sports
Throwing your opponent into the ropes and simply letting him run into you will allow you to pick him up off the mat and perform any move successfully. Repeat until the opponent has been beaten.<P>Another Pattern that will give you a much higher score per match is by letting your opponent punch you once then dodge his attack by moving the player either up or down the ring and counter attack with two punches and dodge the opponent's attack. Repeat until the opponent becomes dizzy. Now is the time to take advantage and execute any two wrestling moves consecutively that require power such as body slam, brainbuster, piledriver or Irish whip. Note If you attempt a third consecutive move without repeating the pattern it will be unsucessful.<P>Cocoa Savage is a bit tricky. The Dodge and Punch pattern will not be very effective with him since he will counter attack with a shoulder block. The best way to attack Cocoa Savage is to let him come close to the player and give him a taste of his own medicine with a running shoulder block. Wait for him to partially get up on one knee and then Shoulder Block him again. Repeat pattern until he is beaten. If you would like, before lowering the Boom on Cocoa Savage get him close to the turnbuckle and perform the last Shoulder Block followed by either two Brainbusters or Piledrivers and finally either two knee drops or somersaults off the top turn buckle, then go for the pin.

The player can choose whether to save their captured ship, try to complete the level, etc. The demo mode will complete after 30 or so seconds and the high-score screen will appear.<BR> <BR> - If the player takes control of the ship and destroys the Galaga with the tractor beam, they will be able to continue playing until the "normal" demo would have completed.
