Also in Defender they changed a few small things. I always play Defender Red Label because the Landers are worth 150 points instead of 100 points like in the earlier sets.
Also on Defender boards, the RED version added cocktail mode which can be set with the dip switches. This allows screen flipping with use in a cocktail table machine.
There are also a few bug fixes in the red version.
