The original Pipeworks Software website hosted twelve screenshots of Godzilla: Destroy All Monsters Melee that were described as "pre-alpha". Only these five of the twelve were archived unfortunately. Some of these can still be commonly found around the internet today, but I don't think I've ever seen the first, fourth, and fifth images before. I'll probably make a compilation of as many pre-release DAMM screenshots as I can find at some point, similar to the one I did for Save the Earth a few months ago.
Huge thanks to Ayasme for sharing the high-quality G:DAMM music files!
