This is what Level 128 looks like in the arcade version of Rampage:

Basically, the vitamin bottle flies across the screen, your points rack up automatically, and your energy bar is completely refilled several times. I think it's pretty stupid to have this appear on the 128th level.

It took me about two dozen quarters to get there. It's interesting to note that there are only two buildings (it's the only level with less than three).

Brian F. Colin, one of the original designers of Rampage, emailed me and had this to say about Level 128:

Plano Illinois was only two buildings because Plano Il is a Tiny town, in which my partner Jeff Nauman was born and raised.
