It's been a while since I played Prime 1 but this one seems to be taking a lot longer. I'm not trying to get all items either. I've had it since Xmas and I still haven't beaten through it. Since you're only on that boss wait til you see the rest =P There's one boss fight where you're surrounded by toxic water swinging from platform to platform with your grappling beam while being pulverized by a boss that can ONLY be attacked from one side and you have to attack multiple points on its wings by using the multi-lock missiles...and you only make it to that bastard after you've killed a boss before it. You've got a long way to go.
