Boring until it gets frustrating.
The game begins with a mildly exciting 'escape from the big, indestructible alien jaunt through the mysterious government complex' gag, but it's all downhill from there. After watching your dad die and your unexplainable, unscathed escape from said complex, you wake to find yourself helped by an unrealistically top heavy female Anime (soldier?), a tech nerd who never takes off his goggles and still manages to think dreads and a head band are cool, and some mysterious, tight lipped government stooge who you can only assume will betray you at some point in the game.
Once you get through the strange cut scenes with the terrible voice acting, it's onwards to shoot slow moving, non-aggressive, unorganized bugs and some equally moronic humans with the same guns you have. What can be said about this over the shoulder shooting action other than: point, click, point, click, strafe left, click, click... you get the idea. One of the more annoying aspects is the seemingly unlimited amount of ammo you will find on such a deserted, frozen wasteland. Could they colonize the planet? Nope, but they brought an ass load of machine guns! Oh, and make sure after shooting and killing every enemy in sight, you run around pac-man style magically depositing thermal energy into your knapsack so you don't freeze to death.
I will note that the boss battles add a dash of difficulty to the game. Although it's more of the 'Damn, this is taking a long time doing the same thing' kind of difficulty. The frustration and surprise comes when you finally get to jump into your father's highly coveted mech suit after breezing through the first 10 cookie cutter levels and matching up with that big bad alien from the beginning. Now, this may be the result of me not being good at the game, but considering I totally annihilated everything in my path before this, I expected the same. To my surprise, I proceeded to get my ass handed to me for the next 2 hours of trying and retrying, sitting through the same cut scene, and getting annoyingly close to killing the damn thing before he wipes me out with his heat seeking....back spikes? At this point I threw my mouse up against the wall, tore the CD out of the drive, and cried myself to sleep vowing to never play the game again.
My advice for you, buy it if you love Ameri-Anime, shooting bugs, and being bored to tears. Otherwise, leave it on the shelf.
