Half-Life Cheats & Tips

If you get trapped by a barnacle (those things with the long, sticky strings hanging down), quickly pull out your crowbar and attack the creature to kill it in one hit. Don't try this if the barnacle is on a high ceiling, though, as you'll take quite a bit of damage from the fall. You can also equip your crowbar and allow yourself to get dragged up to kill the barnacle and save some ammunition.

*Turrets (standing): Avoid lasers and toss a grenade from cover (preferably a corner)

*Turrets (operated w/bunker): Try to run up to a pile of sandbags and duck (if you can't get behind a corner), then if you are safe, throw a grenade into one of the sides - it will kill the soldier operating it.

*Rocket turret (In the "On A Track" level): Real easy to avoid, but can be deadly. Your best bet is to duck behind the controls of your cart and wait to pass it. When you do, shoot the soldier and watch him explode

*Sniper: If you are being struck by bullets and can't see the assailant, it's probably one of these suckers. If you die, reload and pay close attention to the walls. If you see camouflage, get close and toss a grenade into his perch.

*Alien w/hive hand (can't remember the name - it's a big guy): If it fires a multitude of wasps at you, try to run away and duck behind a corner to avoid them. Your best weapon bets are the magnum, the laser, and the crossbow. It's easy to defeat by itself, but in groups they get to be really frustrating.

*Alien w/blue shell, red eye, and the ability to shoot fire from his hands(also forgot his name): This guy's thankfully not very common (I've only seen him twice) but is just plain evil. Rockets, grenades, anything that explodes will be your weapons of choice. Even a full rocket launcher won't take him out, so a lot of grenades are necessary.

Tiny bugs (when found in a pod, can be used as weapons): In the "Forget Freeman!" level, these guys will be in hovering little sacks that rupture when you come into contact. Your best bet is to run away to some place with light, then pull out the pistol and shoot them as they approach.

Hydra (also a boss): These guys will either be in a three-pack (first appearance) or alone (in the desert). You can't kill them with your weapons, so distract them by tossing a grenade to some far-off side where they can hear it, then run like hell to reach your destination before they hear you and kill you (any method of walking will not help you with stealth - you have to distract it)

Fish monster: Your weapon of choice is the crossbow (and you get it before you fight one - convenient). Pull it out and wait for it to charge at you, then fire an arrow and get out of the way. On occasion, come up for air, but be careful when you come down - you never know where it is. Repeat this strategy until it goes belly-up

The final boss, Nihilanth, can be a pretty big pain-in-the-bootay with his portal attack that sucks you into another area filled with enemies.
Of course, those enemies get tougher and tougher, so to not deal with this headache (so much), follow this strategy:
*Nihilanth always puts his hands together (as if in prayer) before he attacks with either a portal or a bunch of lightning balls
*So whenever he puts his hands together, duck behind one of the tall rock spikes.
*Keep in mind, however, that if the portal hits the rock, an alien will spawn from it (no big deal, though)

Well, do you want to now how to get 100%. There isn't alot of water in the black masa. So if you find a pond, of water you can jump and swim under water. If you have 99% or lower jump into the water. Nearly drowned and come up for Air. AND IT WILL RISE TO 100%. This works to on: Blue shift, team fortress classic( diffently),half life source, half life 2, half life death match, and all sorts of mods, an MORE!!!!! Have fun!!!

First you need a crossbow and another gun.Second take out the other gun and save with it out.Third take out the crossbow and put it on sniping mode.Fourth keep the crossbow on sniping mode and load back to the other time when you saved it.Finally no matter what gun you hade it on it will be on sniping mode.

After you shoot the missle in single player mode, turn on no clip, and chase it. But let it go completly out first then leave. As soon as you get out of the area, turn off noclip, and turn on your flash light. You are now in a hidden room.

In the 3rd part of 'Interlooper' , where you see a Garg (a huge monster who can burn you) crushing rocks ans stones to be able to pass through, there will be a small hole behind. When you enter it, you will find a small waterfall, and plenty of water on the floor. When you step into it, your health will recover gradualy.

Before entering the hole, look in the direction where the Garg crushes the huge rocks. You should be able to see a sort of staircase, but smoother than a staircase. In fact, it can be described as a slope. It'll be on the left, stuck to the wall.

Climb on it, and when on top, look to the right. you'll see a tiny lighted room with med-kits and ammunition packs in it. Duck, and crawl into it.
