Half-Life 2 Cheats & Tips

You may have noticed, by default, it's a pain in the ass to have to hold down the left analog stick to crouch, not to mention accidently tapping the right analog stick during a heavy firefight to have your weapon zoom in and you be unable to fire it. These problems can both be fixed by modifying the controls.

Firstly, pause the game, go to Options, then Controls. Select Toggle as ON for crouch, and Toggle as OFF for zoom. You'll notice the effects immediately. Now, go back to the menu, hit 'RESUME GAME' to return to where you were in-game, and then save your game to retain these settings for next time you play.

Grenades have a lot more uses that you initially may think. To throw a grenade, equip one from your inventory, and pull down the right trigger. This will perform an over-arm throw. The grenade will explode after 5 seconds, and it can even be thrown at wall to bounce around corners.

Alternatively, you can crouch and press the left trigger to roll a grenade along the ground. This is only needed in a few situations, but it's nice to know it's there when you need it.

The final method of using a grenade is by running with one in your hand when something is chasing you, then tap the left trigger to drop it. Whatever is chasing you (eg - zombie) will follow after you, then walk over the grenade you dropped and be blown up.

The combine will occasionally roll/throw grenades at you, so quickly equip your gravity gun, pick it up and throw it back at them, to watch their own grenade explode in their face.

The vehicle you use throughout Highway 17 is far more usefull than you give it credit. Here are some tips on getting the most out of it.

1. Use it for cover. When a gunship is bearing down on you, or circling back and forwards, and you are in the middle of an open road, park it sideways across the road and crouch down right next to it. The car will absorb all bullets which the gunships can fire, and while it reloads, jump out and take your best shot at it.

2. Use it as a weapon. When you are surrounded by a huge amount of enimies, whether they be antlions or combine soldiers. Run them over, while using the built-in gun to eliminate others which are approaching. When using the crane, you can also lift it up, and drop it on enimies. Be creative and you'll be amazed in how many ways you can use it.

3. Use it's supplies. There's a crate of grenades attached to the back of it, so when you're running low, make sure you use it to top up.

In Entanglement, where you are fighting with Alyx, let her run through any load screen first, and then wait 15-25 seconds before following. When you follow, a duplicate of Alyx with pop up right in front of you. After the loading, there will be the pop up Alyx right in front of you, and the real Alyx a bit past her.

Not only does this look weird, but you now have twice the firepower to cover your back, although it won't last long. Let them both take the initial fire of the combine in any upcoming battles, but keep and eye out for which is the real and which is the copy, as it doesn't matter if the copy dies, but you must keep the real one alive.

NB: This is a nice little glitch you may or may not come across, it boils down to luck really. However, this is a rare glitch, and not a well documented tip for getting extra firepower, so be thankfull if you're lucky enough to get it.
