Pretty good shooter along the same lines and u.n squadron for SNES,with the exception the levels scroll really slow. Game is pretty tough as well. Clean plain graphics, plenty of power ups and a decent soundtrack all add up to a nice shooting experience on this Super CD ROM. Worth picking up if you are a collector and can find it cheap, which I believe you can these days. I think I paid 10 bucks for mine. Worth every penny.
I too believe that this is a above average shooter, which will reward those who stick with it beyond first few stages. The trick to enjoying this game is powering up your lazer gun and homing missiles.
