Unlock HK Recon Threat Data 
To unlock HK Recon Threat Data get 4 medals 

T800 Threat Data:
Get four medals on level 3. This can be quite difficult because your character gets 
hit all the time and it is hard to dodge the enemies. Go to "Awards" to check what 
medals you received. Note: This was the cyborg from in T2: Judgement Day and 
The Terminator.

T400 Threat data:
Finish all the training missions under the time limit, then press L1 at the mission 
complete screen to see what you have unlocked. 

Turret gun zoom:
When you get to use a turret gun in certain parts of a level, press L3 to zoom in 
3x. This will help you see what you are shooting at, and result in better aim.

Weapon zoom:
On most weapons, you can zoom in by 3x pressing R1. 

Easy Skynet Tech points:
While zoomed in, aim for the neck of most enemies and their heads will pop off. 
Each head is worth Skynet Tech points. 

Game Intro option:
Successfully complete the level 1 under the medium difficulty setting to unlock 
the "Game Intro" in the "Bonus Material" screen.

Easy kills:
Aim for a terminator's head while in battle. If you shoot its head, it will pop off, 
and you will get a lot of Skynet Tech points. Sometimes when you shoot its head 
off, it will run around shooting its gun in the air and then explode.

Adrenaline combos:
Use the following trick for adrenaline combos using little adrenaline. When you are 
about to attack with your electric baton, turn on your adrenaline and start to 
attack. When you land the first hit, turn off adrenaline and continue to attack. You 
will notice that you attacked with your adrenaline combos.

Defeating Endos:
Hold R1 to lock on to an Endo. Then, hold L1 to switch to first-person mode. Your 
target will move from the torso to the head, requiring fewer hits to kill. Then, pick 
up the head for Skytech Points. This will not work well if the Endo is moving. 

Defeating the Terminator:
Keep moving side to side in the hallway and fire, trying your best to dodge the 
bullets. If you want to try to inflict some damage with the baton, you can, as this 
will save ammunition but you will risk being hit or grabbed. Once you defeat him 
he will return, but without the gun. This time, you move around the hallways. In a 
few rooms there will be health, armor, and ammunition. Keep blasting him. When 
he puts his arms up, he is bulletproof. Only fire when his arms are down. Once he 
is defeated he will return again, crawling around the ground. Keep blasting him 
and moving backwards. However, if you hit the end of the hallway, run back and 
roll past him. Then, just keep firing. If you run out of ammunition there is more in 
the next room.

Destroying the Loader:
In level 5, you find yourself in a large room with a huge robot. If you have plenty 
of health and armor, run to the back corner behind the stacks of boxes. If not, you 
can risk going up the stairs on the walkway and grabbing the armor and health. 
Then, grab the C4 on the edge of the stack of boxes and hide again behind the 
stack. You will notice that his shield drops just before it fires. Drop a few blocks of 
C4 (you will have to keep re-selecting the C4) in front of the conveyer belt closest 
to you. Then, run back behind the boxes. Wait for the Loader to go to that 
conveyer belt, pick up the box, and drop the shield, then blow up the C4. Keep 
doing this until it is destroyed. The C4 respawns in case you run out.

Destroying Skynet Tanks:
If you encounter a Skynet Tank, do not waste rockets on its powerful armor. 
Instead, use this trick to take out all the parts. Your best chance is to take out its 
guns first, then searchlights. Then, find C4 to blow up the tracks to destroy them. 
Be careful where you place it -- the tank can burn you with its flame gun.

Destroying Skynet Planes:
This is one of the toughest enemies. to hit. Destroy the plane by firing a R6 rocket 
at one of its weak spots. Do this by dodging the rapid lasers, then hit the engines 
that allows it to fly in the air. Repeat this process until the plane has been shot 
down. Watch out for more cyborgs dropping from the plane 

Electric ball:
In some parts of the game when you use your electric fighting prod and put it 
away to use a gun, the game will think you still have it out. When you leave the 
spot you are standing in, the electric ball at the end of the prod will float in 
the air. It will stay there until you leave that room.
