DXX-Rebirth is based on the late D1X and D2X source ports (which, in turn, were based on the original Descent source and LDescent). The Rebirth Team has spent a lot of time working to improve the source code by fixing old bugs and adding some improvements, while always staying true to our philosophy: Keep it Descent! It is the goal of DXX-Rebirth to keep Descent 1 & 2 alive and well, updating them for modern PCs while also keeping them the same games you remember playing back in 1995! This is the Descent source port. The data files are not included.
