Downloading with Steam on Linux[edit]
As of June 2015, the only game available for Steam on Linux is Strife: Veteran Edition, the rest are all Windows-only, even though source ports exist. It is possible, however to download files meant for another platform. Start Steam with the -console command line parameter, or open the steam://open/console link in a web browser, you should see the developer console.
From here, you can simply type download_depot <appid> <depot> to download an item; the app_info_print command can be used to determine what the depots are. The following are known:
- The Ultimate Doom: app 2280

All the files will be downloaded into the $HOME/.local/Steam/ubuntu12_32/steamapps/content/app_<appid>/depot_<depotid> directory. The original Doom 3 release and Quake 4 will require a CD key, it is not known at this time whether your key from Steam can be obtained through the Linux version; for now, you must run the Windows version of Steam or use another key you might already have.
