This mutator causes players/monster carcasses stay where they were killed.
Max number of carcasses may be set in the Mods menu.
I found 2 different versions of this mutator when I was searching for it.
Neither had a readme file or any other info.
This is the one that works....
Extract both files to your UT\System folder and it should show up in your mutators
list and the Mods menu.
