Twisted Metal: Black

While playing the game, press Select + Right.

At the Highway Loop level, go to the bridge with the gap in it. Go to the side opposite the long tunnel. Facing away from the bridge and to the left on the other side of the wall, you can see two round towers at what seems to be a powerplant. Hit the one closest to the bridge with a gas can. It will fall off and start rolling toward the bridge. Make sure you and no other enemies are in its path or it will break. It will slowly jump the bridge and will make a hole just inside the tunnel. You will find a black cube inside that will unlock the Elevators level in multi-player mode.

Note: The controls must be set to the "Classic" option for this code to work. While playing the game, hold L1 + L2 + R1 + R2 and quickly press Triangle, X, Square, Circle. If you entered the code correctly, the words "Weapons For Health" will appear on the screen.

At the Downtown level, locate the set of buildings connected at the second story on one side of the river/bayou. You can find it easily when you drive between them, since there is a big section of wall that is very visible that you can shoot out to get to the elevators. There is one on each building. When facing the buildings from the river, take the left-hand elevator up. Then, circle around to the back of the building. Along the way you will notice that the ground changes color. About one car length to the left of that line is where you want to creep to the edge and barely fall off. You should hit the cube while falling. If not, you should be on a different level off of the ground -- jump (press L1 + R1) to get the cube. It can be seen from the ground floor once you know where to look.

At the Freeway level, go toward the center of the level to find a large construction site with two big cranes. The one on the right is holding a pipe, the one on the left is holding a crate. Use the ridge between the cranes and the road and aim yourself at the control box of the left crane (at the center box). You only need to hit it once with some kind of missile. The crate will then lower into the construction yard. Shoot it to unlock Axel.

At the Prison Passage level, exit the ship once it docks on land, go to the right (left if facing the ship). Follow the waterline until you reach some crates with a health pick-up. Shoot the crates until a ramp is formed. Go up the ramp and turn toward the side of the ship. Shoot the side of the ship until a opening appears. Enter the opening to find and unlock ManSlaughter.

Successfully complete story mode with all regular and hidden characters to unlock Minion.

At the Suburbs level, go to the entrance to the carnival. Turn left and jump off a hill to land on top of a building with a structure on top of it. Blow up the structure to reveal a hole in the building. Fall through the hole and destroy the panel. A message stating Warthog has been unlocked will appear.

At the Junkyard level, shoot down the airplane that circles around the level. The easiest way to shoot down the plane is with a homing or fire missle while no enemy is around you. The plane will catch on fire, circle, and crash into a wall in the lowest area of the level, that leads to an underground tunnel. The suspended crate's opening faces this area. Follow the tunnel under the sewers, collect the weapons and health, and continue until you see a control panel attached to a large column in the middle of a circular room. Shoot the control panel and a message stating Yellow Jacket has been unlocked will appear. Yellow Jacket will appear inside the destroyed column.

At the Snowy Roads level, go just beyond the barriers toward the cliff in the area with the restaurant, on the southern side of the level (to your right if you're facing toward the road in front of the restaurant). Carefully follow the edge of the level to find a black cube that will unlock the Power Plant level in multi-player mode.
