If you are reading this news bit in anticipation of a new cowboys vs. dinosaurs game, well, I'm sorry, you're out of luck. That would be Gwangi, not Guwange. The latter, released today on Xbox Live Arcade, is a port of a 1999 shooter. The game was developed by Cave, a company legendary among shoot-em-up afficianados. (Deathsmiles, released on XBLA a few years back, is another Cave title.) Guwange is set in fuedal Japan, and the heroes travel on foot, rather than flying around in a spaceship as is typical of the genre.
