Control introduction sequence - During the opening screens, press L1 and R1 to zoom in the image in the background.

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.

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.

Hints & Tips:

Defeating Ground Tanks - If you manage to encounter one at early or later levels always remember to try avoid walking in front of it because if you do it still has a forward mounted flamethrower on it but hand to hand combat is not going to get you nowhere but to weaken its attack shoot the gun arms to avoid getting shot by its lasers. Once Both twin plasma turrets are destroyed you still have another weakness on the tank which has searchlights shoot them and the tank will be blinded but be careful of its canister grenades and flamethrower he won't use it unless your in close range but watch yourself with the grenades it launches but this ia alright if you are protected by heavy armor now place or shoot explosives on the tank to destroy them

Earning Medals - If you having trouble earning medals then try doing some hand to hand combat to get martial master and raging valour but this one has to be done by adrenaline which makes this more lethal and bold to earn the untouchable and sharpshooter ones just make every bullet count and dodge enemy fire as for ground pounder and speed demon kill everything and race through the level to earn the highest score of awards for your performance

Dropped Medipacks from Enemies - If you auto use when low on health medipacks will appear from dropped enemies this makes you have small and large in your inventory

Toggle Adrenaline Trick: I have discovered a little trick on adrenaline what you do is to fight in hand to hand combat with this on and toggle it on and off to get more adrenaline for defeating more enemies

Defeating the Terminator and still get Medals for your Performance - Although this may be a short level but you have to just keep hitting him with all your effort it takes about three battles to deal with the infiltrator his first form is wearing a cloak and is carrying a gatling gun once you defeated the first battle he will get up and do a move when he creates a shockwave to knock you off your feet just keep dodging his attacks when on the second battle and get more health armor and ammo from the rooms in this encounter once you defeated the second battle his legs will explode and will be crawling in the last battle if i was you i would use a grenade launcher to blast him but if you hit him wtih the baton and adrenaline at the previous battle you will still get medals for your performance

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.

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.

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.

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

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

HK Recon Threat Data - Get four medals to get the HK Recon threat data option.

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.

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.

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