Shoot the tankers while they are on the helipad. Wait for Warhawk to hover over the helipad and explode the tankers. Warhawk's shields will take damage. After doing that about four times, Warhawk's shields will be destroyed and the Tankers will stop appearing. Remember to restore your health often on the level, and hide when you need to. Also try using the "Satellite" weapon for major damage.
Electrocute men in Prison Passage level
On the Prison Passage level, you can run over a box marked "Danger High Voltage" and watch the three men who are sitting in chairs get electrocuted. They are near the front of the ship on a platform. The box is right in front of them.
Elevators level in multi-player mode
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.

Minion's Stadium level in multi-player mode
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.

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.
Play as ManSlaughter
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.

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.
Play as Yellow Jacket
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.
Power Plant level in multi-player mode
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.
Prison Passage level in multi-player mode
At the Suburbs level, go toward the downtown area, drive across the gaps, and stop on the second rooftop. Then, slowly turn toward the ocean and look for a power missle on top of the narrow roof nearby. Back-up your vehicle a bit on the current rooftop, and get a good start toward the other narrow rook with the power missle. After you pick-up the power missle, shoot the vent on top of the building to obtain a black cube that will unlock the Prison Passage level in multi-player mode.

Sewer level in multi-player mode
At the Skyscrapers level, go to the bottom of the crashed plane and to the left (if you were exiting the plane) is a small billboard. Shoot down the billboard and it will form a bridge between the gap of the two buildings. Place yourself in the center of the board and aim yourself toward the inner part of the hole. Depending on your vehicle, you will have to drive off at a different speed to get the black cube. Note: You will have to lose a life to get this black cube.
Skyscrapers level in multi-player mode
At Warhawk's Rooftop level, look for where the tankers are coming from on the Rooftop. Then, align your vehicle perpendicular to the building that has hangars that the tankers come out of on top.

Warhawk's Rooftop level in multi-player mode

Off the side of that will be a rotating black cube. Jump off to the black cube to unlock Warhawk's Rooftop level in multi-player mode.
