<div class="paragraph"><p>In 1999 <a href="https://www.idsoftware.com/">id Software</a> released the source code to their
classic game <a href="https://en.wikipedia.org/wiki/Doom_(1993_video_game)"><em>Doom</em></a>
(under the <a href="https://www.gnu.org/licenses/old-licenses/gpl-2.0.html">GNU General
Public License</a>). The game as a whole did not get this treatment, however, which
means that while the <em>program code</em> that powers <em>Doom</em> is free, the actual
<em>content</em> of <em>Doom</em> - graphics, audio, levels, setting and characters - remains
proprietary. The Freedoom project aims to fill this gap and create a complete
<a href="https://www.gnu.org/philosophy/free-sw.html">free and libre</a> first person shooter game.</p></div>
<div class="paragraph"><p>By itself, <em>Freedoom</em> is just the content of a game and must be paired with a
<a href="https://doomwiki.org/wiki/Category:Source_ports"><em>Doom</em>-compatible</a> game engine
to be played: the <a href="download.html">download</a> page lists some
recommended programs.</p></div>
<div class="paragraph"><p><em>Freedoom</em> is actually three entire games, with two single-player
campaigns and one collection of multiplayer deathmatch arenas (<em>FreeDM</em>).</p></div>

<div class="paragraph"><p>There is a massive decades-long
<a href="https://doomwiki.org/wiki/Idgames_archive">back catalog</a> containing
thousands of <em>Doom</em> levels and other mods made by fans of the
original game.  <em>Freedoom</em> aims to be compatible with these and allows
most to be played without the need to use non-free software.  The
video to the right shows a <em>Doom</em> mod running under <em>Freedoom</em>.</p></div>
<div class="paragraph"><p>Just as <a href="https://www.gnu.org/">the GNU project</a> was started to develop a
free operating system to replace Unix, we aim to provide a free
replacement for <em>Doom</em>.  If you have artistic skills (visual, musical,
or maybe you just like making levels!) then you can
<a href="help.html">help us</a> achieve that aim by contributing to the
project!</p></div>

<div class="paragraph"><p><em>Freedoom</em> contains hundreds of original textures, sound effects and
