I created this level as a passtime and also as a test to see if a new single player level for BIA could be made even with a rather buggy editor. I've created a wiki with written documentation on my findings and everything you need to create your own sp map for this game, found at

Credits: This Map can be distributed freely as long as this readme and all five gbxmap files are kept in the package.
This Map has been created by Steven Maes (nickname Pooky on the Gearbox Software Forums) to keep the spirit of the BIA games alive while waiting
