This is a port of a famous dos game called Cdogs its the sequel to Cyberdogs. I believe there was 2 versions of this game available. This one has the odd frame drop but plays very well. Its a bird eyes view shooter and includes missions. This is the SDISO version of the game however you can extract the ISO and use Bootdreams to create a bootable Dreamcast CD-Rom Image.
