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 2 source port. The data files are not included.
