In honor of Ikaruga dropping on XBLA for download -- and you really should nab it -- IGN Retro draws up a list of classic pre-1998 shooters you absolutely must play. These shmups (shoot 'em ups) are real tests of twitch skills and pattern memorization. The list spans a number of platforms, from the Saturn to the arcade, from the Master System to the SNES. Of course, there are many games that fell just outside the ten, like Einhander for the PSone or Wings of Death for the Amiga. And then there's Rayforce. And 1942. And Scramble Spirits. And Gradius Gaiden. And Life Force. Picking these ten wasn't easy, but it was certainly much easier than surviving a bullet curtain in Batsugun.
