That's really cool.

Have you thought about making this officially a fork? With Xonotic moving away from the dark places engine, X:CAE can't really call itself an expansion of xonotic once that happens. It only really means a name change, removing where ever it says xonotic.

Also, I beg you, please change your release strategy. To redownload the iso for every release just seems tedious, not to mention now the second volume. Just releasing a tarball with the altered files since the last version along side the iso would make a huge difference. Having release files like that could even mean an updater script is possible. A bash script could pull the tarball in increments from the current version number.
I had hoped for playdeb to pick this up but they have a long list of games awaiting approval with nothing being done.

Example script:
#!/bin/bash
cd "$( dirname "${BASH_SOURCE[0]}" )"
while :
do
GAME_VERSION=$(&ltcurvernumfile)
GAME_VERSION=$((GAME_VERSION+1))
wget https://sourceforge.net/projects/chaosesqueanthology/files/Rel_"$GAME_VERSION"/"$GAME_VERSION".tar.xz
if [ -e ./"$GAME_VERSION".tar.xz];
then
tar -xf ./"$GAME_VERSION".tar.xz
echo $GAME_VERSION > curvernumfile
else
exit 0
fi
done

You will probably want someone to double check that script though, or write a better one, I am not so good.
