NOTE: Changing your registry keys can lead to system or OS problems. Only change registry values if you know what you are doing or have a registry backup.
Edit your registry and find key:
Right click and create the following new Strings and set each with a value of '1' for Enabled, '0' for disabled:
PlayerInvulnerable : Unlimited Health For You NPCInvulnerable : Unlimited Health For Allied Friends FullWeaponEquip : Get All Weapons DoInGameLoadSave : Load/Save Game Appear in the Options Menu
NOTE: Cheats will only work after a new level is loaded (loading savegame does NOT count). Some people have reported problems with the LOAD function, so you should use the main menu for LOAD purposes.
Level Select Create a string value called "DoLevelSelect" and set the value to '1'.
Now, create 19 string values titled "LevelSelect#" where the number sign "#" is replaced with the numbers 1 through 19. Each of those string values will be assigned a value that corresponds with each level. To get these values, open the Game folder and go to data\levels. Put the name of each file (do not include the '.dll") you see there as the value for each of the LevelSelect# entries.
message: You know how most npc's wont follow you unless you give them weapons? Well if your short on weapons or your just feeling greedy point your gun at the npc thats not cooperating and hold it there for 3-4 seconds. A mini-cutscene should commence and he will now obey orders because you have ''threatened'' him.
Run around the boss in a circle while shooting it with the machine gun. When it is low on health, torch it with the flamethrower and you should have been able to beat it with out taking a single hit. When you beat it, the Thing in the glass in the room will break out and the door will open up with a few guards.
Go in the helicopter. When the pink tentacle appears from it's back, unleash firepower on it. Then turn your attention to the mouth. When you are knocked down to the ground, blow up one of the nearby barrels and watch the creature burn. Repeat this until the intermission starts
On the first level when you are trying to escape the place were they did testing on you at one point you will come across a group of switches and you will need the correct order. The correct order is pull number one then four then pull down four and then pull down four. If you don't do this correctly guards will come in and shoot you
On the second level (when you get out of the helicopter for the second time). You will find a man in the building. heal him and tell him to follow you.after you get him away from the place he was you will see two canisters shoot them two times. after they explode use your fire extinguisher to put out the fire. In this room you will find ammo and a flame canister with one reload.
Always keep your team members well stocked with arms and ammo, even if they are infected. It is easier to kill an infected member and take all his stuff then it is to backtrack trying to find more ammo. Don't waste your medkits that determine DNA. If a team member is infected it will manifest itself in due time. Infact it seems to be scripted. I did a test on a member and it showed nothing. Then 5 minutes later he was a nightmare.
Under the warehouse through a door is your first real boss. As soon as the cut scene has ended keep yourself to the left of the room keeping your back against the door. There is a tentacle that pops out of the wall on the right. Shot gun the hell out of the boss then use the flame-thrower on it until it collapses on the floor. You will have to shoot the little spider things as your killing the boss because there is a hatching bubble just the other side of the boxes your standing next to on the left of the room.
When you enter the door and the second boss is there there will be a junction box to the right of you. Don't bother with it because it is a waste of time. Go up to the boxes to the left of the junction box and slowly move to the side of them. When you have a good aim at him and he cannot hit you shoot him until when you lock onto him the crosshair is red. Then run up to him and flamethrower him and run behind the boxes. Go up and flame thrower him some more. This might take a couple trys but eventually you will beat it.
To get Witley on your team when you reach the dome at the very start where you see Witley before you take a step throw a blue grenade outside into the snow then the cutscene will appear and Witley will be standing there instead of running. Take your bloodtest and use it on him. Give him a weapon and you now have Witley on your team.
If you and your team are up against an army of spiders what you do is-move you and your team into a room with a door control and shut the door, while your in there reload your gun and heal yourself then open the door and kill as many monsters as you can, if there are to many or you are running low on health or ammo close the door again and repeat the process. P.S-dont forget about your team-there no good without amo or a gun!!!!
