Betrayed Alliance

The Sierra Adventure classics are just that: Classics!

Betrayed Alliance is a fan-made Adventure game in the same engine that ran the old classics. Retro EGA graphics, parser-interface, and good ‘ol puzzles!

And best of all, it’s FREE!
Book 1 is now complete and ready to play

Betrayed Alliance Book 2 is in the works now and updates can be found here and on my twitter account, @slattstudio.

Development updates:

Betrayed Alliance is set to be a Trilogy, the first book already available for free. This is a passion project and I will not be charging for any of the games at any point. However, if you wish to patronize this project, please feel free to donate via paypal: (You might want to wait on tipping, however, as I am planning a Kickstarter for November…details forthcoming.)

Tip Jar

If you’d rather patronize my work and get something out of it, feel free to pick up one of my excellent works of fiction.

Note: The game currently runs on Windows, Mac, and Linux, but the game will only run with music on Windows. This problem should no longer be a problem with Books 2 or 3.
