Overview
This guide is, over-all, a collection of dozens of guides to have one ultimate guide for Half-Life 2. I am making this mainly for my own convenience, and for my love of the Half-Life games; however, I will be properly updating it (hopefully) occasionally.
Introduction
By: AZIN
Welcome to the GREATEST GUIDE for Half-Life 2! As I plan for right now, this guide will NOT account for either episode. I am, as described in the basic desc., making this for new players (as if) and people, like myself, who want everything in once place.
Half-Life 2: The Basics
Instead of writing all of the basics down here, which is, in a way, overkill, I have opted to link the Half-Life 2 dedicated wiki for the basics: Half-Life 2 Wiki[en.wikipedia.org]
Map Codes (With Chapters)
All of the story chapters can be unlocked by typing this into the console: sv_unlockchapters 15
NOTE: These commands DO NOT require sv_cheats 1 to work!
To load these maps, simply type:
map *level name*

===CHEATS===
Below this Section marker is the explanation of cheats as well as the cheats themselves!
Setting Up/Enabling Cheats
To be able to use cheats, first you have to activate the developer console in the settings. To do this, go into the main menu of Half-Life 2 and open up your settings. Under the keyboard section, there should be a button that says “Advanced…” just above (and slightly to the left) of “Ok”.
After pressing Advanced, enable developer console by checking the box and pressing both “Ok”s.
After enabling the console, to open it press the tilde (~) key [This key is directly underneath escape.]
After that, to use almost any commands it is essential to enable sv_cheats by typing sv_cheats 1 into the console.
You are now good to go to use the cheats below!
NOTE: sv_cheats 1 disables achievements!

===Backhopping===
This section is for the back-hopping basics!
“What is Backhopping?”
The source engine, which HL2 runs on, allows for some pretty…..*wacky* movement. In Half-Life 1, which ran on the GoldSrc engine, bunny hopping, also known as bhopping, is a frequent technique seen in speed-runs of the game. Half-Life 2 also had the same exploit when it was initially released; however, the movement trick was soon patched out.
To counter-act the effects of bhopping, VALVe essentially added a negative effect that slowed the players motion when going faster than you are supposed to forward. This effect actually created a more efficient type of bhopping known as backhopping. By essentially bhopping backwards, speed is grown exponentially thanks to the debuff gained implemented from regular bhopping.
“How do I backhop?”
To make backhopping easier, it is highly advised that you go into your console as explained earlier and type both of the following:
bind mwheelup +jump
bind mwheeldown +jump
This makes it where if you scroll your mouse wheel you jump; and, compared to the space bar, makes bhopping quite easy once you get used to it.
Rather than explain it really indepth here, it would be better to show you.

Now, I could put this in my guide, which is kind of the point of this whole thing, but this person did so much better than I ever could so here you go: [link]
