Halloween Harry (later renamed in Alien Carnage) is one of the last DOS platform games produced before the shift to first-person shooters.
Obtaining the game

- The game won't read files from the current directory before falling back to harry.-0, and won't run without harry.-0 present. Therefore modified files must be inserted into harry.-0 before the game will see them.
- There are two files left over from game development inside order.bnk. These two files are called build.bat and make.bat, both of which are DOS batch files to create the order.bnk file itself. From this it can be seen that there are two programs used during development, one called kit which creates the .bnk files, and one called dizfile which may create the corresponding .fat file from the .bnk.
