Hint: Betrayal: Falling soldier:

Grab a soldier and jump off the building where green
arrows are pointing. As you land on another building, the man
will disappear from your hands and you will hear him screaming.

Hint: Chemical Effects: Terminal:

When the level starts, go all the way down the hallway to Bruce Banners
left. You will find a large door. Go through that door and either sneak past
or defeat the guards. There should be a door to the left of you. Go through
that door. Once through it, either defeat or sneak past the guards. Next, stand
in the large circle with bars around it. Press Y at the screen inside
of the circle with bars around it. This should take you to the fifth floor.
Once there, you should see a large computer down the stairs. Either defeat or
sneak past those guards. Go to the right of that big computer. You should find
a smaller gray computer. Go to it and press Y. A code terminal screen
should appear. Enter the desired terminal code. Note: Per game, you can only
open up the code terminal once. Use it wisely unless you want to repeat the
entire process.

Hint: Destroying helicopters:

If you get something to throw, pick it up then jump on the roof. Jump while
on the roof. If done correctly, you can blow up the helicopters.

Do a Super Sonic Clap while in a rage. Point in the general direction of the
helicopter, do the attack, and it will explode. Note: This will not work if
the helicopter is directly above you.

Hint: Destroying missiles:

Perform any kind of punch toward a missile when it is flying at you. If
timed correctly, you can punch the missile and it will fly back to the soldier
who shot it then blow him up.

Hint: 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 .

Hint: Waving soldier:

In challenge mode, go to time attack mode 1. Wait until the soldiers appear.
Go to either side of the building. Pick up a soldier, jump, and throw him off
the building. Sometimes another soldier will wave good-bye to him.

Hint: 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.

Hint: Paralyzer attack:

If you are facing a Boss or Gamma guard and you are angry; grab them, then
press Gamma for a hurting and heroic move. This also works on Ross’ robots.

Hint: Tank shields:

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.
