RoadMap: We are on track to a 'version 1' release of this game by October 2017 *
About: Dave Gnukem is an open source retro-style 2D scrolling platform shooter, inspired by and similar to Duke Nukem 1 (a famous original 1991 game that launched the Duke Nukem series). It currently runs on Windows, Mac, Linux and various other platforms. It is written in C++ and uses LibSDL libraries. It features an integrated level editor.
Let me know if you are interested in contributing to this project.
Please donate, or else I'll make more games like this.

9 September 2002 I will, for now, probably be continuing with Dave Gnukem. I have added some levels contributed by T.O.G of SpookWare. To get to them, select "missions" from the game main menu, and select them.
31 January 2002 I will, for now, no
longer working on Dave Gnukem. This may or may not be permanent, I
don't know yet. If you are interested in taking over this project,
please let me know.
23 September 2001 Release 0.54. Sound support is back (thanks to Kent Mein)
(although the sounds themselves still suck), implemented a high score
list, redefinable keys, rudimentary load/save game support, monsters
can now shoot, and, as usual, miscellaneous bugfixes and improvements.
The SDL_mixer library is now required.
2 August 2001 A BeOS port of 0.53 is now available at http://www.bebits.com/app/2428 [presently defunct link ~2017]. Thanks to David Marshman [was at: http://www.silvan.demon.co.uk/beos/ - new link unknown] for that! Now if someone would just offer to do a Mac port ...
24 July 2001 Release 0.53. Ported to SDL, finally! Not only is the SDL implementation of the graphics/input are about half the number of lines of code as the DirectX version (DirectX is a pretty clunky API) but the SDL code works on Linux too, eliminating the need for extra Linux code (previously I used GGI).
15 July 2001 Release 0.52. Minor improvements and cleanups (graphics, new features e.g. fans, dynamite, level background image) and rewrites of some sections of code (monsters, lifts, conveyors, bullets)
4 July 2001 Release 0.51c. More minor updates (balloon, ACME falling block, disk, a few graphics improvements) and some reasonable code cleanups.
21 June 2001 Release 0.51b. Minor updates (new pickup types, spikes, GNUKEM letter bonus, a few graphics improvements).
17 June 2001 Release 0.51. Added an
object factory. Rewrote the door/key code. Can now pick up letters.
Added shootable solid blocks. Can now shoot security cameras. Added
green crawly things. Added purple flags. Added shootable banana. Added
high score list (almost).
16 June 2001 Got rid of djGameLib, made a number of other cleanups, added a spiky bouncing ball. No sign of the Linux version yet :)
13 June 2001 Uploaded a new version,
Windows changes only. Minor cleanups and graphics changes. I don't
the Linux version compiles anymore. This is a temporary situation, I
would like to fix it sometime. I have general plans to try port
this game to SDL, and phase out all my own library stuff. Added some
doxygen documentation for the source code. Fixed some problems
that prevented the Windows version from compiling and running at all.
GPL (GNU General Public License) version 2. See http://www.gnu.org/ for more info on GNU, or the COPYING file included in the download for the full license.
Linux (You will need the SDL (Simple DirectMedia Layer) 1.2 runtime and SDL_mixer 1.2 library installed (http://www.libsdl.org/)
NB: It is important to use the above links! Some software sites are linking to specific versions of the
download file (e.g. ending in 0.53.zip), and this results in broken or outdated links when I upload a new version. The above URLs map
to the latest version.
If you want, you can also use this 88x31 banner for your link: (Right-click/save-as in most browsers)
(Yes, 88x31 banners are "so 1990s" - but so is this game!)
There is a lot to be done still. Although I have
fairly limited time available to work on Dave Gnukem, I do plan to
finish it, even if it takes a few years still. Help is wanted on the
Documentation: Get the readme file up to date. Get the German readme up to date. Improve the doxygen documentation.
Sound: Find (or make) some decent sounds for the game.
Coding-wise, multiple sounds should mix (currently if one sound is
played, any existing sound is stopped). Also need a "stop sound"
function, and functions for looping sounds.
Graphics: Good-quality graphics wanted for the game and interface.
Levels: Need level editors to produce levels.
Level editor: Should be improved.
Input: Joystick support.
Porting: I would very much like to see a MacOS port (should be fairly easy, because of SDL).
Coding: More monster types, loading/saving of games, recording/playback of games.
See the github issue list for more possible ideas. Let me know if you want to help.
I started writing this back in 1995 in my first
year at university (actually it goes back longer than that, before that
there was a pascal/assembly version),
and work on it intermittently whenever I get time and inspiration. It
a DOS-based 16 color EGA game; I then converted it to Linux/GGI, then I
did a DirectX-based Windows port, and then I converted it to SDL. The
code is a bit
messy due to it's colourful history, I was slowly trying to clean it up but more or less gave up.
The original Duke Nukem 1 (shareware version) can be downloaded here: 1duke.zip (Approx 300 KB).
(The official web page is at http://www.3drealms.com/duke1/index.html, but don't even bother unless you feel
like being put through the hell of trying to download something from GameSpy/FilePlanet.)
Note: I am not trying to write a clone of Duke Nukem 1. Although currently very similar, I have no interest in importing the actual DN maps or graphics, which belong to 3DRealms.
The name is a pun on 'Duke Nukem' and 'Gnu' as a sort of 'hat-tip'/reference to the open source license/model.
* This wasn't a retro game when I started on it (~1994ish), but it's taken so long it's now 'de facto' retro genre. So we are copying also the Duke Nukem Forever model of taking forever to be released.
