Name that Game

This game was originally published in Japan as Assault Suits Leynoss and was created by NCS corp. In the US, it was brought out by Dreamworks software in 1990. The premise is:

Earth's outcasts have returned from the depths of darkest space ready to retake the planet for their own, with the will and the weaponry to match. The Earth Defense League isn't about to let them do it, though.

This great game is so hard as to make it nearly impossible without a cheat code to make you invincible. What was this game called in the US?
