Defeating Fire Ghosts:
To kill the Fire Ghosts, first reduce them to an ash pile. Then, shoot the pile of ash to finish them off. Otherwise they will come back and gang up on you.
Quick Revolver Reload:
Press Reload then do a dive. Your revolver will be reloaded in one second.
Game Trailer:
Remain idle at the new game screen. The trailer for the game will eventually start playing.
More Revolver Ammunition:
To get more ammunition for the revolver that you get in the beginning, instead of waiting for that one person you find to die from the electric chair, kill him with the sickle that is found in the cell. The gun will have a lot more ammunition.
The Shining Reference:
After you leave the Asylum where you do all the tasks with Doctor Killjoy, you will be in an area which has what appears to be a nine-step staircase. Walk up it and follow the wall. Sou should run into an opening that has walls made of some type of vegetation. You will hallucinate and see images of your children. As you follow them, they will run down one way. While continuing to follow them you will encounter a corpse that is sitting up against the vegetation wall, with an axe laying beside him. This is a reference to The Shining, where Jack Nicholson is chasing his son through the labyrinth and dies against one of the walls inside. The Shining was also mentioned in the game's bonus material.
Iron Maiden References:
On many of the walls you will find 'If there is a God, then why has he let me die', which is an exact quote from the song 'Hallowed Be Thy Name' by Iron Maiden. Also, on two walls near the beginning of the game, the words 'This is a world that has gone very wrong for me', which is also from the same song ('In a world that has gone very wrong for me'). This is difficult to read because its written in smeared blood.
The Ring References:
When you are in the abandoned World War II bunker, you will encounter a desk with three phones. Two of them are are green and the other is red. Pick up the red phone first and you will hear the a girl's voice say "You will die in seven days".
Destroying Dr. Killjoy's Movie Projectors:
In the Asylum level, the key is to destroy all of Dr. Killjoy's movie projectors. After destroying all the movie projectors, you will be able to open doors and eventually get out of the building. If you cannot destroy the projectors, find a way to block the projection. You will see these movie projectors towards the end of the game again. When you get into a room to battle Dr. Killjoy, destroy the projectors. There is one on the second floor that you cannot destroy. One will be in a crate hanging above. Find the rope end and cut it to destroy the projector. Turn the switch on next to the center table and stand underneath the contraption hanging above. Get zapped, then throw a fireball at the monster Torgue that is chained on the wall. The wall will explode, allowing you to exit the level.
To defeat Dr. Killjoy in the Asylum level, you must shoot all the projectors, which can be done easily by standing on the surgical table without harm to you, since Dr. Killjoy brings the Slayers back to life anyway. There is one camera in a cage above; shoot the rope holder on the wall to destroy the camera. Another difficult one is on the second floor. It can be destroyed by shooting the fuse box below it on the wall.
Tool References:
There are two references to a song by the band Tool called 'Ticks and Leeches'. Early in the game look closely at one of the walls. You will see the words 'Ticks & Leeches' which references the song. This is not a coincidence, as later in the game, about where the Noosemen appear, written on the wall are the words 'Suck Me Dry', which is a phrase constantly repeated in the song. Also, the phrase 'I hope you choke' or 'I hope you choke on this' can be found written on a wall some time before the gun fight with the guards and the man with the gun turret. This is also part of that song.
Easy Bad Ending Sequence:
At the last section before you fight the final Boss, enable the 'All items and weapons except for Gonzo Gun' code. After the confirmation message appears, you will be covered in blood. Complete the game and you will unlock the bad ending without having to play the entire game with the normal requirements.
Filling Insanity Meter:
In the level where there is a group of shower areas, go to the left and just dodge the 'syringe throwing' ghouls to get to the next door. You can stick around and shoot some of the ghouls to fill up you Insanity meter. When running across the shower areas, do a 'zigzag' pattern to avoid getting hit in the back. There will a fire blocking your way. Shoot the fire extinguisher to put out the fire.
Getting Torque's Last Insanity Move Easily:
On your way to help the cop get to the Radio station, their will be an endless amount of Slayers jumping out of the trees. Keep killing them in Insanity mode until the experience bar will not fill anymore. Stop the slayers from appearing, shine the spotlight on the tree.
Helping Clem Off The Island:
Go inside the boat and go up the ramp. Look to your right to see two barrels held up by a chain. Shoot the chain and the barrels will drop. Then, throw a stick of dynamite or a Molotov cocktail and the ship will catch on fire. This will stop the monsters from coming onto the shore.
Extinguishing Fires:
In the level where Torgue is in a big break room and a fire is blocking the door, turn the sprinkler on. Look for a drainage and block it with a soda machine. The water will then flow toward the fire and put it out. You will also use this same technique towards the end of the game, where the 'fire ghost' blocks your way with fire.
Hallucination Mode:
When you see the monster Torque becomes, kill him. If you cannot kill him, try using the Gonzo Gun.
Gonzo Gun:
When you get the room in the basement where you hear your kid scream behind a wooden door, blow up the canisters near it. Open the red door and turn left. There will be a wooden box. Drag it back near the hole in the wall at the top. Climb it and you will see a dead guard. Later in the game there will be a Gonzo Gun.
Constant Images:
When you enable the 'All items and weapons' code or two or more codes, you will constantly receive images from Dr. Killjoy's room, where he has all the ink blot pictures everywhere on the walls where the man that had his eyeball taken off. To stop this side-effect, simply load a saved game before you entered the codes.
Passing Through Caves:
When you get inside a cave system, leave flares in the path that you have been to. This will prevent you from coming down the same path again, wasting time and your flashlight battery. Watch out for blood spots on cave ceilings where the 'decapitated chokers' appear.
Crossing The Rock Quarries:
In the rock quarry, there is a fiery hole in the ground. Use the crane control to knock a big rock off a ledge. The rock will drop, block the fiery hole, and keep the Slayer from coming out. In the other rock quarry, after helping another inmate to cross, swing the crane towards you all the way to the left next to the platform across the way. You will have to jump onto the rock that is hanging from the crane. Get a running start and jump onto the rock. If you do not do a running start, you will not make it on top of the rock.
Lighthouse Gears:
To get the lighthouse gears to turn, throw a stick of dynamite at the handle. After this is done, Torque will be able to turn handle.
Defeating Slayers:
After getting through the Asylum, the Slayers will start to reincarnate after being killed. The only way to keep them down is to blow off their heads.
Defeating Main Liners:
In the shower area where countless Main Liners keep appearing, turn the water off on all the showers and kill whatever remains. They will stop coming.
The Crucible Reference:
When Tork and Ernesto defeat the Inferna around the stake, Ernesto refers to the story of little girls accusing locals of witchcraft. As a result, they were burned alive for practicing witchcraft. This is a reference to The Crucible by Arthur Miller.
Crossing The River:
When you get to the point where Torque has to cross a river and the bridge is out, shoot the chock underneath the truck. The truck will roll onto the river bed. You can climb up the truck and get to other end of the bridge. In another scenario, a speeding prison bus will appear. Get out of the way and the bus will crash into the river bed.
Torque's Family Archives:
Successfully complete the game after following the good choices when given the opportunity.
Defeating Enemies:
In the level where there is a C.O. with a machine gun, go upstairs and shoot the other C.O.'s coming down the stairs. When you get upstairs, there is a hole on the floor where you can shoot the C.O. with the machine gun downstairs.
Torque's Archives:
Successfully complete the game after following the evil choices when given the opportunity.
Monster Archives:
Successfully complete the game after using the monster transformation as many times as possible.
Playable Introduction Sequence:
Successfully complete the game, then start another game to play a 'bonus level', which is the original introduction sequence with 'director's commentary'. To hear the commentary, jump on the crow that lands in a corner.
Torque Actions:
Remain idle during game play and Torque will start doing strange things, such as poking himself with a shiv or dropping his family photo. He will does different things when you hold various weapons.
Defeating The Green Smoke Creature:
First, turn off all four pipes leaking green gas in the corners of the room. Then, shoot the rope tied on the wall, near the far end of the room, to drop the box hanging from the ceiling onto the vent that the green light is coming from. Then, shoot the other rope tied to the wall near the railed door to drop the covering to the vent. The last vent covering is in front of boxes which will explode when you shoot them. After these vents are blocked, drag the box over the vent nearest the dead inmate. Next, wait for him to get in front of the fireplace and take the from of a man. When he does this, turn the crack so that the gas pushes him into the fireplace. Then, run over and shut the door.
Defeating Enemies At The Dock:
In the docks, where you have to battle the 'Insane' Torque, find the .50 cal machine and shoot him with it.
On the last level, you are isolated out on the docks and have to fight the monster that is your alter-ego. Make sure you have your shotgun (in the trailer in the preceding level). Immediately as he appears, shoot him. Walk forward, to the right, and up the ramp going to the fenced off piece of land. Run towards the fence and to the left. Walk off the land where the fence ends. There is a little shelf of land that you can stand on. On all difficulties except 'Impossible', you can stand on this shelf and shoot the monster until he dies. It takes about sixteen shots from the shotgun. You can then jump back on the land (this may require several attempts) and deal with the hypo-monsters. The best way to kill these is to shoot the ammunition boxes that are spread around the level. You can also throw bombs in their vicinity to kill them. If you are playing under the 'Impossible' difficulty setting, you can drop down to the shelf of land but must move up a couple of yards or the monster will jump and you will be thrown into the water. Once you are safe, he appears for a few seconds then runs down to the main dock then jumps repeatedly. Eventually, he comes back. You can shoot him with the shotgun and throw cocktails at him until he dies. The big monster at the end is relatively easy to kill. When coming from the fenced-off land back to the dock, there is a fenced door to the right that you can kick open. In three of the four places where the monster appears, you can hide out and not be hurt. If you are energized with the blue plasma, you can throw the plasma at him and avoid being drawn close. When he attempts to shoot fire at you, jump back to avoid being burned. There are boxes to hide behind if he comes up on the side nearest to the fenced-off land. If one of his whirling blue spirals hits you, just shoot at him in slow motion as he tries to hit you until you are a safe distance way. If you are a good person throughout the game, a man arrives in a boat and you will jump aboard to get off the island. If you are a bad person (i.e., shooting potential allies and everyone else that you encounter), the ending changes. You will throw a big box at the man who comes to rescue you (sinking his boat), change into your alter-ego, then go back towards the prison to apparently fight everybody who attacked you on the way. The alternate beginning involves you being put into a prison cage and changing into your alter ego (monster) after you have been provoked.
