This shoot em’ up has made its way to several platforms since its debut in 2001, all the way from the Sega Dreamcast to Android OS. It’s popular and you’ve likely seen it pop up somewhere, though a lot of people have heard of it, it doesn’t seem like a lot of people have experienced this title first hand. Did it just gain popularity at the wrong time or is it just infamous like the Atari 2600’s E.T. game? Seeing how the game is still being played today and has been ported over to everything makes the answer a bit obvious.
