Duke Nukem Payback Time is a 1 level demo. It is for version 1.4/1.5 and the file is 2.9MB in size. The file name is paydemo.zip. It was released on Feburary 3, 2000.

Duke Nukem Payback Time Demo is another one that looks like it would have made a nice TC. Large, well designed and detailed, with good gameplay. I rate it as good with 3 out of 5 stars.
