To do:   Document duplicate boss rooms. Document prototype it can be found here.

Duke Nukem II is a game where you wear a red vest and fight aliens in space.

The engine uses three 16-color palettes ingame (one displayed onscreen at once), because of this, while it can run on EGA cards, the graphics will be displayed incorrectly.

For some unknown reason, this frame of the ending is skipped over. Coding error? Deliberate cut? We may never know.

Anti-Piracy

The registered version of Duke Nukem 2 uses a simple anti-piracy method that was in common use at Apogee at the time: The game checks for a FILE_ID.DIZ file (commonly used as an archive description on BBSes) that contains the following:

████▓▒░ ALERT THE SYSOP IMMEDIATELY! ░▒▓████
████████████████████████████████████████████
THIS FILE IS NOT SHAREWARE -- it is ILLEGAL
and forbidden to upload this copyrighted
software to bulletin boards. If you see this
message on a BBS, please request that the
Sysop remove this software IMMEDIATELY!!!
█▓▒░ OR CONTACT APOGEE: (214) 278-5655 ░▒▓█
IT IS ILLEGAL TO GET THIS FILE FROM A BBS!
████████████████████████████████████████████

This effectively labels pirated copies of the game on BBSes so that SysOps could quickly remove them. Upon completing any level, the game will unceremoniously end as if you had chosen to quit. After the high score display, a message will appear before taking you back to the main menu.

To do: Examine the exact details of how the checksum is, well, checked.
