Spawn Grunts

Activate cheat mode, then use the /impulse 76 code to activate the Grunt-O-Matic. A message to start a new game in order for it to work will appear. If you want to continue where you currently are, just quicksave, then quickload the game. Once you have quickloaded, type in the code again to spawn a Grunt. Note: You must have the /nocliping code on before you spawn the grunt because he will be spawned close to you. If this is not done, a message stating that the monster spawned is stuck in a wall might appear and the game will end. Don't spawn the Grunt in a closed position or the same message will appear. The Grunt you spawn will see you as a hostile. To have more fun, use the /notarget code and spawn a number of grunts to do your alien hunting.

Starting hints

  • After the "accident", you will discover a scientist giving CPR to a security guard. Wait about 20 seconds to see the outcome, which usually results in the security guard being revived. He is not useful at this time, but return to him after getting the crowbar. Kill him with the crowbar so he can not fire back to get his gun and ammunition.

  • Soon after this, you will ride an elevator upward. Have the gun ready and shoot the monster attacking the security guard; a few shots should do it. This security guard can cover you until you reach the main entrance area.

  • One important strategy in the early game is to use your "allies" to your advantage. When you no longer require the services of a security guard, kill him and take his ammo. A scientist is also useful in drawing enemy attack. Be careful not to harm an ally when another security guard is present, as he will attack you. Also be aware that monsters can sense your allies; and even if you crawl, monsters can hear your allies' walk.

  • You may run into the following glitches toward the start of the game. There is a scientist sitting in front of a damaged instrument panel, in the area of the first scientist who opened a door for you. This scientist is invincible. You can shoot or beat him with a crowbar, and all he will do is whine. This also saturates the area with a significant amount of blood.

Then, repeat the steps of shooting his eyes and the orb until he dies.

Exploding scientists

On the level where you must pick up your HEV suit before the accident, enable the /impulse 101 code and select the crowbar. Walk up to a scientist and wait for him to do a scripted event such as scratching his chin while looking at computer readings. Keep hitting him with the crowbar. When the scripted event ends, depending on how many times you have hit him, there will be an explosion of meaty chunks.

Dislocated body parts

After the disaster, in anti-gore mode, select any level and shoot down one of the men. He may not disappear. If he does not, keep hitting his bag with a crowbar (if visible). He should appear have all his body parts dislocated. Note: This occasionally works better if you creep up behind him with a crowbar or enable the /notarget code. To get in anti gore-mode, go to the options menu and use the password protected area on the visuals.

Game Of The Year Edition

  • Get the HEV suit and activate the impulse 101, impulse 105, and notarget codes. Reactivate the cheat screen, and keep using the impulse 101 code until your HEV suit is full. Choose the high explosive (press 5 twice) and return to the lobby in Sector C Test Labs, where the security officer is on the computer. Go behind the desk and toss a high explosive under the desk. Walk anywhere you want, but not past the loading point, then detonate it. Walk back and the security officer should be on the desk. Talk to him.

  • After the scene where the experiment goes wrong, you will go through a series of transportations, etc. After that, you should end up in the experiment room. Exit both rooms and you will see a scientist performing CPR on a guard. Use the codes to get any human weapon and shoot the guard. The guard will say something along the lines of "You're gonna regret that".

  • Activate the impulse 101, impulse 105, and notarget codes and get the Magnum. Walk up to a scientist from behind, then shoot him in the back of the head. Certain ones will make a noise, stand for about ten seconds, then fall and die.

Talk to dead man

  • After the accident, when you go to the area where there is a scientist sitting on the floor and another is comforting him, enable the /impulse 101 code. When the man that is sitting down is talking, pound the standing man with your crowbar until he dies. When the old man is done talking, the dead man will talk to you.

  • After completing the first part and all of the destruction starts, you will be in a room where two scientists let you into the machine that you put the sample in. If they are dead, then this trick will work -- it is after the accident, and not before. Enable the /impulse 101 code and use the eye scanner that is lop sided, next to the door. Go through when it allows you to and you should see a scientist giving Barney CPR. Use any weapon, preferably the crowbar, and hit Barney. He will talk even though he is dead on the ground.

  • Kill A Barney or Scientist. If the body does not disappear, crouch next to it. Press USE and the Barney/Scientist should talk.

Look inside G-Man's briefcase

To look inside G-Man's briefcase, first enable the noclip code. There are two ways to do this trick: the first is to begin from the start and ride the train until you see the G Man for the first time. He should be in a train next to the one you are in towards the end of the ride, by the radioactive water. The other way is to go through the train ride, then walk around the halls of the laboratory to find him talking to a scientist. When you do this, go towards the G-Man. Get as close as possible to his briefcase without going through it (this make require several attempts). In one side, there is paper, three pencils and a pistol. On the other side is a computer with a message and a picture of the G-Man. Note: When doing this where the G-Man is talking to the scientist, you will not be able to understand what the two are saying.

Interlooper

During the third part of the "Interlooper" level, get to where you see a Garg (a huge monster who can burn you) crushing rocks and stones. To be able to pass through, there will be a small hole behind. When you enter it, you will find a little waterfall and plenty of water on the floor. When you step into it, your health will gradually recover. Before entering the hole, look in the direction where the Garg crushes the huge rocks. You should be able to see a sort of smooth staircase-like slope. It will be on the left, stuck to the wall. Climb on it. When on top, look to the right to see a tiny lighted room with med-kits and ammunition packs. Duck, and crawl into it.

Fun with spawning

Activate cheat mode, then use the entities code to get a list of the creatures in the location you are currently in. Usually, when you try to spawn a creature, you have to use the noclip code to levitate in the air and spawn the creature nowhere near any objects. If a part of a spawned creature is spawned within a wall, ceiling, or another creature, the game crashes. However, if you enable the developer 0 code, the game keeps going even if a spawned creature is stuck, but the creature has yellow dots around it. Also, bind the spawn commands to unused keyboard keys; for example bind X "impulse 76" or bind y "give monster_scientist". The impluse 76 code works everywhere, and the hostile grunts created with it are easy to place where you want them; as they appear in front of you, rather than above. Now, enable the noclip code and fly around pressing the bound keys. Watch as Barney's Aliens and Grunts battle it out while Scientists run around being slaughtered.

Soft landings

If you jump or fall from a high location, use the Tau Cannon Gun (gun hat fires orange bolts). When you fall, use secondary fire to hold it and release it immediately before you hit the ground. You will land without losing health. You can use this technique to get to high places by doing this from the ground.

Grunt smell comment

During the first level, enable the /impulse 101 code and go to either one of the two security officers (Barneys) guarding an area. Use the /impulse 76 code to spawn a Grunt near them. Do not spawn the Grunt in a wall or Barney or the game will end with an error message. Kill the Grunt quickly and leave it on the floor for a couple seconds.

Barnacles strategies

  • When trapped by a Barnacle (creatures with long, sticky strings hanging down), immediately take out your crowbar and attack to kill it in one hit. Do not attempt this if the barnacle is on a high ceiling, because you will take a lot of damage from the fall.

  • Equip your crowbar and allow yourself to get dragged up, then kill the Barnacle with it to conserve ammo.

Trapped scientist

Right before the accident you will enter a room with two scientists. They will talk to each other. After they are done and have opened the door, make one of the scientists stand on where the door should be. Once you go into the room, the door should shut behind you, with the scientist trapped in between it. Once you have put the rock into the laser, run into the room with the two scientists and hide out of sight from the laser. This should make the sequence to Zen not happen. When the next chapter begins, the scientist you trapped in the door should still be there.

Are you trying to reload your most recent save? You're going to have to load an earlier one if you keep dying on the most recent one.
