New one:
ZARZON/SATAN OF SATURN (!), 1981 SNK/Taito
Really awful fixed-screen shooter, known as ZARZON in the US and originally called SATAN OF SATURN in its native Japan. Neither Zarzon nor Satan Of Saturn are really any good. Take out waves of UFOs, then diagonally descending ships, then a comet, and then you fly to Saturn to destroy bug-like enemies and then 3 dragonflies. Sounds perhaps kind of cool but it really is poorly made and unmemorable. I saw ZARZON at a drive-in theater snack lobby, I believe, in Vancouver WA back in 1987 when I went to see CREEPSHOW 2 with my mom.
