To ulock Holiday Havoc you have to kill 30 guys in enduance mode!!!!

When your in the kitchen, you go up the ramp and go around the counter and you'll see a microwave oven. When you see it, go inside and you will see some weapons. But do not shoot anything at the microwave walls or the microwave oven door will shut and you will be cooked. (IF YOU HAVE 1 OR NO LIVES DO NOT ATTEMPT THIS, BUT IF OYU HAVE 3 OR MORE LIVES JUST COOK YOURSELF FOR FUN.) This is a very important hint for this game.

Go to "Playground Peril" in tournament mode and go to the edge witth the swings. Once there, jump and shoot at the middle swing [the one with the black thing on it] and a statue of axel will land near you, grab it to unlock him.

First choose a car and pick endurance for Holiday Havoc. When the game loads, go to the christmas tree and shoot it until it falls over onto the fireplace. Then drive your car to the top and face the lamp on the other side of the room. Drive off and do a quick 180 turn and shoot a missile at the closest stocking. When you hit it, it should catch on fire. Do this until all of them are gone. when you hit the last one , a statue of Mime should come out of the chimney. go over and pick it up to unlock Mime.

In the menus, choose Slam as your car and Tree Top Rumble as the level. When you have a special, use it on the nearest car. (make sure you are in the open) While you have the enemy, drive over to the outside edge(not the inside edge because they will bounce right back) and wait for the attack to end. When it does end, the enemy should be thrown over the edge and destroyed.

In Holiday Havoc, shoot the train to get health. When you do the train will blow its horn and a health will appear behind it.

Kill 20 guys in endurance mode to unlock the Buster's Lanes level.

In "Playground Peril" level shoot "big duck" to get a health.
