Frequently Asked Questions – Left 4 Dead (Build 23968273)

Is Left 4 Dead completely free?

Yes. This Build 23968273 release is a free download. It includes the full game and a separate online fix folder so you can play co-op with friends without buying the game on Steam.

How do I install Left 4 Dead?

Download the 3.1 GB package, extract it to a folder excluded from your antivirus, and run the game as administrator. If you want online play, extract the online fix folder and paste it into the main game directory, overwriting when prompted.

Why does the game say Steam must be running?

That message appears when the online fix has not been applied. Extract the online fix folder included in the download and paste its contents into the main game files. After that, online play works without Steam running.

Can I play Left 4 Dead with friends online?

Yes. The online fix included in the game folder enables online and LAN co-op. We tested it with two players and it worked after applying the fix.

How do I change the language from Russian to English?

Open the in-game options menu and look for the language or audio settings tab. You can also edit the config file in the game directory. It is a quick change, not a reinstall.
