Had this for a long time, my uncle introduced me to this yeas ago. Once of the many great games he got me into.
Carma is awesome, I like the freedom it offers aswell as the blood and gore (if its the right version).
I did start a Let's Play of Carmageddon. In fact I might actually carry it on.
Check it out;

Yes I used Fraps - this game runs great via the Windows setup and shortcut, I had to enable the blood version - sorry the zombie or robot ones suck :D
Hope to chat to more of you Carma fans.
