Based on Moonrat's cp_eturnius_a3
I've added textures, removed some points and changed the respawn rooms a bit. While it's looking finished, it still has quite a few bugs that don't necessarily break the game. Since I am using a pre-made map, Feel free to edit this for yourselves, but don't forget to credit Moonrat for this awesome creation!

WARNING: MAP STILL IN PROGRESS! THERE ARE ERRORS AND BUGS SUCH AS CUBEMAP ERRORS.
