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, I’d love your help:

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.

Betrayed Alliance Book 2 has been funded on Kickstarter in December of 2021 to help fund the creation of music and a physical game manual
