Freedoom is a project to create a complete Doom II-compatible IWAD file which is Free Software' The IWAD file is the file used by Doom which contains all the game data (graphics, sound effects, music, etc')' While the Doom source code is Free, you currently still need one of the proprietary IWAD files from id in order to play Doom' Freedoom aims to create a Free alternative' Combined with the GPL-licensed Doom source code this will result in a complete Free Doom-based game' The Freedoom project has already succeeded in creating a complete set of replacement textures for the original Doom games, as well as a large amount of extra material (sound effects, graphics, sprites, etc)' All of the Freedoom material can be freely redistributed, modified and reused without restriction provided credit is given to the project'
Limit-removing port required+For commercial IWADs primarily! If you want to play mods or custom levels, use the official Freedoom IWADs instead! Final Doom compatibility de-emphasized. Where it creates conflicts with Doom II mods or texture definitions, we prefer the Doom II side of things. Final Doom-specific maps and mods may never look completely right in Freedoom, as a result... All levels are now guaranteed to have co-op and deathmatch starts. Completed and enhanced set of Evilution and Plutonia textures.
The HTML documentation (eg, NEWS and README files) are generated with a style based on Freedoom’s own website, rather than the default AsciiDoc styling.
Phase 2’s internal DEMO1 has been replaced, thanks to some odd vanilla quirks that could cause it to desync in some (but not all) conditions.
The sailor monster type is formally banished from Freedoom’s own levels, and remaining uses of it were removed.
Incongruities between the actual game and manual have been fixed.
The make install targets have been consolidated to behave more similarly to how the pre-built zip distributions are: a split between FreeDM and Phase 1+2, rather than installing each of the tree IWADs independently (and thus getting their own /usr/share/doc directories, for instance).
We now have a manual rendered to beautiful PDF format. Thanks to Simon Howard, the project’s founder.
A strong focus on vanilla compatibility has been sought for this release. Most, if not all, levels should work now.
Final Doom compatibility de-emphasized. Where it creates conflicts with Doom II mods or texture definitions, we prefer the Doom II side of things. Final Doom-specific maps and mods may never look completely right in Freedoom, as a result.
FreeDM has seen a major overhaul, with most maps being modified, with new additions and removals of the weaker levels. It now benefits from the use of Aquatex and Egyptian textures in some of its levels, giving a more vibrant feel than before.
Phase 1 gets a lot of mapping love in this round, fleshing out the levels and tweaking difficulty levels so easy, normal, and hard are all accounted for. There is a new C3M5 by Mortrixs.
Phase 2 MAP01 saw an overhaul, simplifying its design in significant ways to improve the flow around the level.
Two maps in Phase 2 were replaced due to being recreations of Doom II maps. Jayexetee and GooseJelly get credits for the new ones, in MAP06 and MAP26.
Maps in Phase 2 in general have had some slight re-arrangement based on difficulty levels and themes. A new MAP06 by Jayexetee is included, the old one taking the MAP18 slot.
All levels are now guaranteed to have co-op and deathmatch starts.
New power-up (stealth, overdrive, and ultra-overdrive) sprites.
New necromancer (arch-vile) sprites by Urric.
Some weapon and ammo sprites have been tweaked and improved.
Completed and enhanced set of Evilution and Plutonia textures.
New skull-switches by MissLav.
New SKY4 based on an astronomy photograph.
Tweaked player sprites and HUD face by Ferk.
New tracks in C1M2, C2M3, C2M8, MAP03, MAP12, MAP22, MAP25, MAP26, MAP27, DM03, DM06, DM09, DM17, DM24, DM31, and DM32.
All files in-tree have been renamed from *.mus to *.mid. The file format must always be MIDI. This makes it easy on music composers to actually work with the files.
Unix script and metadata
Metainfo (formerly appdata) and desktop files have been brought up to the latest standard specifications and recommendations, using reverse-DNS for the project identifier, and a self-evaluated content rating.
The launch shell-script changed the PORT environment variable to DOOMPORT to avoid conflicts with the genericly-named PORT. It also builds a sensible default DOOMWADPATH environment variable to assist ports that do not have a hard-coded fallback.
The script no longer tries to look for boom, zdoom, nor prboom by default, as these are ports no longer maintained.
Freedoom’s build system now has a hard dependency on Python 3, in anticipation of Python 2’s end-of-life.
We have moved from ImageMagick to Pillow, a Python library for graphics manipulation. It provides faster build times as well as API stability.
GIF files have been replaced with PNG files. True PNG file format transparency is used instead of a cyan background.
ASCIIDOC and ASCIIDOC_MAN variables have been added to the Makefile to control the AsciiDoc implementation used to generate HTML and man page files.
The COPYING.txt and CREDITS.txt files includes the license and contributors of Freedoom respectively, both files unmodified.
