Kill Greys Fast
When a grey has it's shield on, you can take it out way faster if you have both alien technology guns on you with ammo. As soon as a grey appears, get out the plasma launcher. Fire that directly at the grey, this will also kill any black ops too, When the plasma is done killing all of the black ops, all of it's power will focus on the grey's shield. As soon as this happens, go to your previous weapon and start firing rapidly at the shield. Repeat this as many times as needed to destroy the shield, which is usually 2 times. If your plasma launcher is empty, the SMP's work the second best.

Fighting Black Ops
Once you get to the part of the game where there are Black Ops agents you should switch to your mutant form to shoot parasites at them from any distance and they will follow the agents until they are caught as long as you have mutagen. It is an easier way of going through the game and not being annoyed by them.

Defeating the Super Beast
When fighting the Super Beast, rather than running straight at him, run around in a circle. When he gets near an explosive barrel, shoot it. It does more damage then the BBG. Watch out for his plasma shooting arm as well. When you finish, Edgar will talk to you, and you get to see him.

Moon Landing Conspiracy
When you reach "Lies of the Past: Checkpoint 4", you will ascend in an elevator. Exiting the elevator, you will see a replica of the Moon's surface, a model of the U.S. space suit, and a shuttle the United States used to reach the Moon. This is in reference to the Moon Landing Conspiracy, claiming that the U.S. never actually reached the Moon, and faked the landing to beat the Russians in the space race. Additionally, go to a building behind the crane operations and scan a top secret file. Go back to the secrets in the campaign menu and play Doctor Cray's diary to hear him say something similar to "Man certainly has been to the moon but the horrors of the alien life form that reside there have never been revealed to the public." This refers to the theory that there is alien life form on the moon and that the government chose to hide it from the public.

How to unlock the Nitro blaster
To unlock this weapon, beat the first Main enemy (boss). Look around once you beat It. The Nitro blaster is on the floor by the wall where a dead mans body lays. Once you found it you can use it as many times as you want, however it takes away your health a bit every time you use it. This weapon can freeze any alien except the big ones. It will freeze them by shooting out a Nitro gas freezer. Once you freeze an alien (it's frozen for about 35 seconds) You must shoot it with a different weapon or else it will dry up and you might be screwed. This weapon freezes them so fast you can freeze five aliens 5 seconds at the same time( depending on their size).
