Just unzip this file into the Descent directory. To start descent with
this level as level 1, simply type BRATTICA to start the game (instead of
DESCENT). When you exit Descent, the batch file BRATTICA will restore
everything back to the original Descent levels.

If you want to run BRATTICA as a mission instead, simply rename the
BRATTICA.MS to BRATTICA.MSN. Start Descent as usual and start a new
game and select BRattica as the mission.
