Found a large JPG with lots of text and images. I think it comes from High Voltage themselves. Anyway, I didn't read the text incase of spoilers (although I doubt there is spoilers and a few words have "CENSORED" across them. I just wanted to play it safe, so I just looked at the images.)
It has a few examples of locations, enemies, weapons and tells you where the games titles comes from.
