Source Engine Installing

    IMPORTANT! First of all to play any supported game you should install the base Source Engine launcher.

    After download, check the filename, your browser probably could rename .apk to .zip, so rename it back to .apk. Then you should install that APK.
  1. You need to obtain the game supported by this port on Steam store platform, and yes, it's not free.
  2. Obtained game you can then download using Steam client on PC or using Valve-on-Android tool that allows download games from Steam using Termux for Android. For Half-Life 2 and Episodes please use steam_legacy beta branch to download the supported version by this port. For some multiplayer games use previous_build branch.

  4. Now, if you downloaded using PC, create the folder named srceng in the internal storage on your mobile device. SD-card is not recommended to use as it can cause slow loads and write permission issues. Open the downloaded from the Steam game folder and copy all folders except bin folder to the srceng folder on your mobile device. To preserve the integrity of the files being copied, it is highly recommended that you copy files to your mobile device in an archive such as zip or 7z and unpack using ZArchiver.

  6. Select the srceng folder in launcher, if you have different name or path of it. Don't select any subfolders like hl2 or portal
  7. You are ready to launch the game. For desired game use launcher linked in supported games list, for Half-life 2 use Source Engine launcher.
