Hudson have performed a commendable job of converting the Seibu Kaihatsu sprite shooter adding in the CD quality soundtrack over the standard Hu Card release. Only those most grizzled gaming vets need apply - especially if you can keep your eyes on two different areas of the screen at once and have a steady trigger finger when it comes to the surface bombs. (Apologies for the poor cover images - the reflective cover doesn't scan well.)
Second hand. Manual cover impressions from the CD case and slight scuffing on the edge as is common with this title. Disk scratching.
