The Mission Demo is for version 1.4/1.5. It has 2 levels and the file is 215KB in size. The file name is m1demo.zip. You will need to rename the miuser.con to user.con. Also the level2.midi file caused the game to crash at the start of level 2. If this happens to you too just delete it. It was released on October 14, 1999.

The Mission Demo has 2 short levels with simple level design and fair gameplay. The pigcops strength has been increased from 100 to 400. (I checked because it was taking too many shotgun hits to kill them.) Level 1 is a bombed out city level. The tunnel are the end was a bit of a pain but I made it through. Level 2 is a continuation of the first level with a lot of newbeasts. I rate this demo as fair with 2 out of 5 stars. It's worth playing through once.
