Defeating soldiers with their shields up
When you are in rage mode and encounter soldiers in their shields, do Hulk's Earthquake attack. Their shields will fall and you can take them out .

Defeating super robots
The super-robots are the steel-made hide-weaponry guards inside the Desert Base. To defeat them, get them to clump together. Then, jump over the pack of them and run in a circle around them. They will use their energy-beam attack, but as you run it will hit more robots, damaging or destroying them all.

Soldiers and Alphas
Unless you are Super Hulk, Alphas can withstand a full powered gamma blast, but soldiers cannot. You can tell them apart by the color of their uniforms.

When a tank has its shield up, you cannot go through it, but your Gamma Claps can. It also reduces the withstanding. You will find health and rage.

Gray Hulk: Additional comments
After you unlock the Gray Hulk, he will say things such as "And you think your car stereo is loud" and other comments.

Glitch: Get inside propane tank
When you are Hulk and in level 3 or 4, find a big propane tank. Jump up and charge your punch. Make sure not to have done any damage previously to the tank or else it might explode. If timed correctly, you will be inside the propane tank. You will see Hulk inside with flames near his body. When you jump again, you will get out of the propane tank with a slight chance that it will explode if you land on it.
