* To possess an enemy, go close on him, then press the 6th button, now you can use that enemy like a playable character, and you can use his moves too! (a screen appears with a description of one of the enemy moves). For leave the enemy body and return to your normal character hero, press the same key. Try to control different enemies and have fun to switch on them!! Find what of them are most powerful and how you can take advantage of their moves! Remember that you can't possess a boss, and also you can't possess nobody if your lifebar is empty; also, when the enemy possessed dies, the player is still on action, but is lifebar remains empty.
* When you engage an enemy, you fight still versus one of them, and in that moment you can go back and forward on him without turn your shoulder on him, you can also execute a block when the enemy attack simply press the opposite direction on him. If you engage groups of enemies, you fight one enemy at once, while the others stay far of you waiting that you defeat the first enemy before they attack you.
* After you've beaten the last boss, Dr Wong will challenge you giving the chance of one last battle before you can terminate the game : this final battle is identical to the bonus stage, but you can choose one of the 4 boss to fight versus the other character boss controlled by CPU. This is the only moment on the game where you can control a boss. If you win this last battle you can see the real final of the game, if you lose you'll obtain a game over.
