Linux Source Code

This page is rather stubbly and could use some expansion.
Are you a bad enough dude to rescue this article?

To do:

The Doom wiki has a bunch of articles going over the source code, including this one.
Make sure to add technical information and where stuff is located.
Stuff found only in the leaked code should be on its own page.
There's likely more.

The source code of Doom was December 23rd, 1997. It is actually the code of the Linux version and not the original DOS one, which was cleaned up by Bernd Kreimeier, mainly to remove use of third-party code such as Paul Radek's DMX sound library.

Interestingly the source code makes mentions of some unused features that aren't present in the final game. (Note: these also apply to Doom II and Final Doom as they are based on the same engine/code of this game).

Unused Quit Messages#

There are several, uh interesting unused quit messages defined in the source code:

fuck you, pussy! get the fuck out!	you quit and i'll jizz in your cystholes!	if you leave, i'll make the lord drink my jizz.	hey, ron! can we say 'fuck' in the game?
i'd leave: this is just more monsters and levels. what a load.	suck it down, asshole! you're a fucking wimp!	don't quit now! we're still spending your money!	THIS IS NO MESSAGE! Page intentionally left blank.

The first seven messages are under a comment saying "FinalDOOM?", but this was added by Bernd Kreimeier when he was cleaning the source for release to the public. These messages were never intended for Doom - they were "development mode only" messages written by John Romero. "Ron" referred to Ron Chaimowitz, then CEO of GT Interactive, the publisher of The Ultimate Doom, Doom II, and Final Doom.

Automap Asteroids#

There are some references in the source code release for an Easter egg that would turn the automap into a game of Asteroids. The code was later found by John Romero, but as it turns out, very little of the egg was actually completed - just some data structures and basic collision detection. Oh, well.
