checked-part ->A.P.B.: Press Start and Siren to enable a level 1-8 warp screen; press Gas, Siren, and Start to enable a level 1-16 warp screen. ->Gauntlet II: If you stand still for 30 seconds, all the doors in the level will open up. If you stand still for even longer, all the walls will turn into exits. . Battling Thief: The thief will follow your exact path to reach you. This means that if you walk in a straight line, the thief will follow you in exactly the same manner, which can make it much easier to kill him. . Freeze Thief: The thief will follow your exact path through the mazes. If you push a block across your path, blocking your way, the thief will be unable to track you down. However, if you cross your OWN path later, the thief will be able to find you once more. The thief will appear at the same point you appeared at the beginning of the level. If you wait for him to appear and kill him at the starting point, you can prevent him from returning by leaving his treasure bag untouched. The bag will stay on his entrance location, and prevent him from reappearing. . Mystery Bottles: Question Mark bottles are food if you eat them when your health total ends with 27, 47, 67, or 87. ->Mortal Kombat 2/3 Random Selection: When playing either Mortal Kombat II or 3, random character selection is done by pressing U+A. This has been changed from the original due to the use of [START] for pausing the game. ->Mortal Komabt 2 Smoke: Smoke can't be fought in this version of the game due to the fact that pressing [START] pauses the game. Normally, you'd access the Smoke battle by playing on the Portal stage and pressing D + Start when a "Toasty!" message appeared. ->N.A.R.C.: As you exit any door, hold U. If done correctly, your character will be stuck at the top of the screen and enemies will be unable to hurt you. You will still be able to bust them, though. Try this in the first level; hold U as you exit the subway. . Mr. Big Bonus: After you kill Mr. Big, you'll find a vault filled with gold; grabbing the gold will yield a large point bonus. Grab all the gold, then wait; dogs will appear. Let the dogs kill you. You'll restart the level and be able to get all the gold in the vault again. . ATM Bonus: If you find an ATM, walk up to it and press U for cash.
