Speedball 2: Tournament Demo
Brutal violence you say? Sport you say?
I hope I heard that right, or I'm wasting my time and yours when pointing you toward the Speedball 2: Tournament demo. It's 30.72 Peggles, and, well, not that great. But that's the joy of demos. You can find out if it's the right kind of not that great for you.
Alternatively, you could head here and play the proper Speedball 2. Probably in silence, unless you've got DOSbox working nicely. I can't find which license this is "abandonware" under, so it may be dubious. Bitmap Brothers, are you ok with our playing it for free?
