If you start a new game, your progress on the achievements Zombie Chopper, One Man Army, and Hack Attack! will be reset to zero (unless you've already completed them). Starting a new game will reset those achievements I just listed if you haven't yet completed them, which is why the changelevel command is better. This doesn't count as a cheat and is the same as doing a 'new game' at the start of a chapter, except with more specific locations to choose from to start at, and it doesn't reset achievements like 'new game' will. Most achievements, with the main exceptions being Zombie Chopper, One Man Army, and Hack Attack!, will not extend past one 'map' segment, so if that's the only achievement or Lambda Location you're missing, you can teleport straight there and save some time.


This goes like 'changelevel d1_trainstation_02', for instance. The final command to tell you about is the 'changelevel' command. Having this turned on helps you keep track of where you are in this guide. It's small and unobtrusive in the top right corner but if you did want to turn it back off again you can use cl_showfps 0. This will let you know what map you're on, and will also show your fps. It has been reported that you can't get achievements if cheats are activated. It should hopefully already be set at this, but in case it isn't, you should do it now. The first command you should put in is "sv_cheats 0". (Most people know this by now considering how long HL2 has been out.) Pressing this key will pause the game and allow you to input console commands. The default key for this is `, the tilde, left of the number 1, and one row up from Q on most keyboards. To do this, go to Options, then Keyboard, then Advanced, then enable developer console. The guide is written in a mostly spoiler-free style and generally assumes that the reader has already played the game and is simply using this to collect missing achievements with.įirst off, enable the developer console. Hello and welcome! I created this guide for PC users because we have access to the console and can jump directly to any achievements or Lambda Locations that are missing, a feature not present in any other achievement guide at the time I originally wrote this.
