Suffering, The

Use the following trick to defeat the creature on the last level at the dock. The big creature will smash open a gate that has a control device that will lower a machine that shoots out a purple beam. Dodge the creature's attack and stand so a beam will hit you. There is a delay between beams. After being hit, you will glow. Press R to throw a glowing ball. Aim for the red spot on its chest. Keep throwing balls until the creature falls in the water. If you cannot throw any more balls, stand under the beam to recharge.

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.

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

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.

In order to not get any health damage when a Main Liner jumps on you and tries to stab you, press Health constantly. The Main Liner will jump off Torque as usual, but no damage or dizziness will occur.

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.

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.

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.

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.

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.

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. Note: 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.

Remain idle at the new game screen. The trailer for the game will eventually start playing.
