Basically, 4 pastel colored, infinitely tall towers that extend from an abyss below. Somewhere before the halfway point of the 'actual' tower stops there's some sort of zone that changes your player's camera to an F8 cam and you die with the message:
[NAME] has fallen into the white abyss!
Just thought it'd be fun for a dogfight to take place above an evil abyss sort of thing. I mean, really.
