As the development cycle for Alpha 4 is going to be a particularly long one, we've decided to split it into several parts. The first is this one, Alpha 4, and we'll follow up down the line with 4.1, 4.2, etc. This is the first part of our step towards implementing the Fortitude quest line, which is a series of smaller SCPs, along with a few extras. It's shaping up to be fairly large, especially in comparison to our other updates, and with our limited team size and scope, you'll need to be patient. We'll do our standard update video once Alpha 4 is complete, unless there's enough interest in our current plans and progress. The public build will now be stepped up to Alpha 3, with Alpha 4 rolling out to patrons, and limited playtesters. Additions:
