The first thing we must do is go to the GameMaps [www.gamemaps.com] page where we will have access to a wide variety of maps for Left 4 Dead.



When they are inside the page, they should choose the map of their preference and then click on DOWNLOAD



And 3 download options will appear, of which we can only choose one of the last two options, select one and then click on DOWNLOAD to start the download.



When the download is finished, you will have left a file zip



We open the zip file and they should extract only the file .vpk



When they have extracted the .vpk file, they should move it to the folder:
Left 4 Dead < left4dead < addons



Once inside the addons folder, you should move the file vpk



And that would be it, now I will open the game to verify that the map was installed correctly.

When they are in the game menu, they go to the section of Extras and then Extensions.



If you installed the map correctly, a map will appear in the Enlargements .

Here I will be leaving a video for those who want to avoid reading the entire procedure above or simply those who did not understand the explanation above :)

Note: I am recommending that you activate the subtitles, since the video is in Spanish
