The expansion for the 1st ed. BB was called "Deathzone", but I have no clue how rare it is and rules it introduced to the game.
P.S.: before anybody asks, yes it indeed has the same name as the 3rd ed. expansion which, in fact, was not "Deathbowl" as Traveler (wrongly) pointed out, but Deathzone, too.

(maybe inhaled too much paint?)
