This is a pretty fun game and I was wondering if it would it be at all possible to get Blood running on our ITs. It was released in mid-1997 and has modest system requirements:

Intel Pentium 75 MHz CPU
16MB RAM
80MB HD space
256 colour VGA
DOS 6.2

As far as I can tell it doesn't require OpenGL support and actually uses the Build engine, the same as Shadow Warrior and Duke Nukem 3D. While the source code hasn't been officially released, there are several fan projects such as Transfusion, a port to the Quake engine, and ZBlood, a port to the popular ZDoom engine.

We can already run Duke3D, Quake and Shadow Warrior so perhaps this could be a possibility?
