Install instructions


Unzip the download to a location you want to store the game. Open AlienWorld.exe.

You may be prompted by Windows 10 that "Windows protected your PC" by preventing the app from running. Click the "More Info" link in the dialog box, then click "Run Anyway" to start the game.


Unzip and run the app. Do the thing where you tell MacOS to run an unsigned app. Right-click and open and then do it again or something? You know what I mean.
