Alpha 4 will be the first major update of Bitrim showcasing elements of gameplay. There will be some simple puzzle examples and new locations.
The plan is then to try and get onto Desura alphafunding, do some advertising, and then continue to add to build the game.
A “Prologue” version of Alpha 4 will remain as a demo, but all further updates will be for paid users only!
Remember: You can pre-order Bitrim by buying the Prologue version above. You'll get an offline client version (instantly) and full access to Bitrim when it's released, including alpha/beta access.
