In the latest issue of Otaku USA (February 2008) there's a removable fold out poster for Godzilla Unleashed. I thought it was just going to be another reprint of the game cover, but it's nicer. It features the background of the game cover, but with a different Godzilla 2000 pose, and the following monsters: Rodan, King Ghidorah, Mecha King Ghidorah, Mothra (imago), Jet Jaguar, Anguirus, King Caesar, Kiryu, Baragon, Krystalak, Destoroyah, Gigan, Orga, Biollante, and Megaguirus. The poster is about three pages long.
The back cover of the issue features an ad for the game. Additionally, there's reviews of Latitude Zero and Mikadroid near the back of the issue.
