There's a PsOne game (also on the Saturn) - I know I should say PSP to please youngsters, but hey, I had to give up namin' em PSX not so long ago- port of a somewhat obscure coin-up shooter you might want to look at, if you like this kind of game : Tempest X3
It's provided with 100+ levels of weird digital insects blasting, and even features a trippy mode
Can you think of some more console shooters (on the Playstation, the Amiga CD32...) , whom authors were obviously inspired by old (if not primitive) arcade games ?
Examples ? Deluxe Galaga, Datastorm...
