Hint: Meltdown:
Rather than going through all four chambers, only go through the first one. Retrieve coolant, bring it back, and put it on the ground near Dr. Hamilton. Next, fly back into the labs three more times, repeating this strategy. You can do the meltdown much faster this way.

Hint: Mountain Strike: Easy disposal of vehicles:
When you get to the big room after the first laser grid, there is a place in the middle where there is some lava. Look carefully to find it. When you see a tank, stand next to it and hold X to carry it. Take it to the lava and drop it in.

Hint: Uprising: Easy disposal of vehicles:
When you encounter a tank, lift it up by standing next to it, then hold X. Fly over the walls and you will see some water. Press X(2) to throw the tank into the water.

Hint: The Comet move:
Start flying by very gently pressing R1. Then, start Speeding Bullet (press R1 hard). Immediately before you start Speeding Bullet, launch a Heat Blast (press Triangle while still flying and Triangle again when you just held R1 harder). Do not change your route of flight after this is done. If done correctly, Superman should look like a red comet. This move can be used very effectively against Bosses. It does more damage than Speeding Bullet and Stuns... However, it cannot throw your foe away like Speeding Bullet.

Glitch: Flood Damage: Walk on water:
In the level "Flood Damage", you can walk on water by holding a civilian. When walking on water you can drop the civilian and catch him again.

Glitch: Infiltration: Freeze game:
When the "Infiltration" level begins, use Heat Blast and Clark should hit the gun-like object. Immediately run forward and Clark will say "I need to find a way to deactivate that thing". It will show the gun-like object with smoke on it. Switch to first person view and look slightly to the right. You should see two scientists talking. Fire your Heat Blast just below them on the wall. After that, go to the place where you have to sneak past the scientist. The scientist will disappear and the blaster will not work. After you have to tap X, the game will freeze.
