Here are all the weapons you use in the game. Don’t forget, most guns have
an alt fire.
Pistol
Just your basic handgun. Has a lot of ammo in one clip, so that helps. A solid fall-back weapon if you need it.
Magnum
This thing is perhaps one of the better guns you have. It’s usually a one- hit kill on the smaller enemies. It has a decent range when you need it, but the limited ammo hurts.
Crossbow
The sniper rifle of the game. You only get one bolt a clip, so each shot is crucial. The time it takes the bolt to fly will sometimes cause a miss, so just make sure your shot is right on.
ALT: Zoom
SMG
This gun will pour bullets into targets, but the accuracy is bad; you will basically unload an entire clip on one enemy just to get a kill.
ALT: Grenade, a valuable tool that will explode on contact
Shotgun
Your basic boomstick. Use it at close range for ultimate effect, and it does have a decent range for a distance. Great against all enemy types.
ALT: Fire two shells
Pulse Rifle
Rather than a human machine gun, this is a Combine rifle with the same effect. The only downside is that you chew through the ammo in a hurry.
ALT: Energy ball, the bane of Hunters
Grenade
Simple enough. Toss, stand back, and then there’s a loud bang. You can hold five at a time, so don’t be afraid to use one on big groups.
ALT: Drop it in front of you, rather than tossing it
Rocket Launcher
The most powerful gun you get. Shoot where you lay the laser beam and the rocket will follow the dot.
Crowbar
The classic melee weapon of Half-Life. Use it to smash wooden planks and crates. If you have to use this for an actual weapon, you got problems that are beyond my skill to fix.
Gravity Gun
The X-Factor of the game. Aside from the puzzle-solving aspect, using this gun as a weapon will be critical for big fights. If you have big objects like rocks and barrels and saw blades, pick them up and send them into the bad guys. Gas tanks and flammable barrels should be used at perfect times, otherwise you’ll have them blow up in your face for various reasons.
Enemies
Lots of different bad guys in this game.
Zombies
A simple undead enemy, but in the Half-Life universe these guys have headcrabs on their lids. The headcrab is the spot you want to aim for. Once the zombie is down, there is a chance the headcrab will stay alive, so keep an eye on it after it falls off.
There are three other types beside the regular, white t-shirt sort. There are fast zombies, and they are the loud ones without skin. Don’t be intimidated by this type because they usually only need two shotgun shells to the head.
There is the headcrab-carrying type. This kind will be dark, hunched over, and covered with poison headcrabs. It attacks by tossing the crabs toward you, and it has a pretty long range. These guys take a lot to kill off.
The final type is the Zombine. These guys were first faced in Episode One and Alyx gave them their name. Of course they are just a zombie Combine. They are tough to bring down and they have a fast stride to catch up to you. Their signature attack is to stop, pull out a live grenade, and then go suicide- bomber on you. You can steal this grenade with the Gravity Gun and toss it, or you can simply outrun the Zombine and let him self-destruct, or you can knock the grenade out of their hand.
Antlions
These are basically big bugs. The smallest, regular type is fast and can glide through the air. You need to backpedal as you blast them with shotgun shells.
A new addition is the Acidlions, which are clear and look just like the normal types. There are two things to know about these guys: they spit acid with an extremely long range, and when they die they will blast acid nearby.
The big boss type is called a Guard. Guards are big and will try to crush you. They only have one attack, the charge. So sprint away from them, get by a wall, and then step out of the way to let them run into the wall. Use the time as they are stunned to pump your strongest ammo into the bug’s body.
You run into one guard during a chase sequence in the hive where you don’t have to fight it. Later you face the same one along with his friend outside. You should use the many red barrels to help take out at least one.
Combine
The Combine take the longest to show up in this game. The soldiers are your basic bad guys with guns. They’re smart and they like to use grenades against you.
Striders are the biggest of the bigs. You run into them during the final fight of the game, but you sure do run into a lot. Thankfully the sticky bombs you are provided will make the Striders very weak. Sprint to a bomb, pick it up, sneak around the back of the thing, stick it with the bomb, and then shoot it with the handgun. Easy, the Hunters escorting the Striders are what make that fight so tough.
The helicopter is only fought once. The idea is similar to the Strider attack plan, just with the chopper’s own mines. Pick up a mine with the GG and send it into the bird. Do this about five times and you can move on.
Other
Not many other enemies in the game. You have your Barnacles that hang out tongues from a ceiling to grab you. Put something in these tongues to distract the things, or just shoot them. If you ever stop and start raising off the ground, it’s not magic, it’s a Barnacle.
Perhaps the headcrabs count as a seperate type. They crawl on four legs and they leap to attack you. You get three flavors: normal, fast, poison. Use the shotgun when these things are about your feet, and use the pistol when you are a distance away and out of their range.

To get the boxes from the high platform throw rocks at it with the CG.
again great walkthrough, one hint for you though if you havent already figured it out. The last radar cashe on the sling hanging off the cliff. Just throw the rocks, simple, sometimes the solutions are right in front of you but these are the hardest to find because you're looking for someting complicated. That's why I love these walkthroughs. thanks again
Excellent walkthrough! I really try not to use them but somtimes you just gutta. Most walks are full of errors and misleading but this one is great. Not too much info just enough to keep you moving. Thanks
