[HL2] 100% Achievements Guide

If you want to make things a lot quicker by loading directly into the maps, you can use a Console command to do so. But first, we need to enable the Console.

Click the Options tab in the menu
Select the Keyboard tab on the top of the small window
Select the Advanced tab on the bottom
And finally check the option Enable developer console. and apply the changes

---

With the developer console enabled, you can now press ' (Default key) to open it, and now type the command "Map (Map Code name)".

The part with the orange outline is a mere example of a map code name.

What you are doing is basically telling the game to load directly into a section of the map named ___, now if you don't know the code names for each map of the game, there is a link in the very top of the guide that leads to a list of Half-Life 2 maps. Copy the map code name the achievement section is asking in the list and paste it on the console, it should look like this:

If done correctly, you will load successfully in the map, but if you really want to, you can unlock nearly all achievements in a single run.

To make things a little faster, you can activate the Steam Overlay in-game, the default key Is F11. When Steam Overlay Is enabled, come to this same guide. Now you won't need to Alt+Tab everytime to check the achievement progress.

Description: Survive the second turret standoff in Nova Prospekt. (This achievement is unskippable)

Requirement: After the first turret standoff in Nova Prospekt, you will find yourself in a two hallway room, all you need to do is survive. If you are playing on the hardest difficulty of the game, you can do my own strategy right below:

Before anything else, do not pick up the turrets; picking them up will trigger the Combine assault, so only pick them up when you are completely ready. The best place to holdout without being damaged is the second room with a supply crate. You will use the various props on the hallway to barricade the entrance to the second room where the supply crate is located, make sure there are no gaps in the head level. The reason why you need to do this is that the many enemies that have guns will never shoot you as long as you don't see their heads. Also make sure you don't bring the turrets in the room, because if you do so—they will try to shoot down the combine, as well breaking the barricades. When you think you are now ready, pick one of the turrets and quickly run to the barricaded room, crouch in one of the corners and finally do anything else you need to.
