I bought this on a whim really knowing nothing about it. From the outset its a fairly fun game, controlling the camera yourself with the wii remote is tricky but once licked its fine and quite useful when your pinned down and trying to spot where enemy fire is coming from.
Certain controls are quite annoying like the grenade deployment, one quick accidental flick of the nunchuck and boom you thrown a grenade when you didnt mean to and ruined your stealth approach, and even when you want to throw a grenade it very hard to make it go where you want.
There are several brilliant features though, my favourite is being able to deploy your bio-chip enhanced gun called gunnar (they thought long and hard about that) as an automated sentry, this allows all sorts of tacticle options from crossfires to diversions.
The graphics are pretty good to, not your standard depressing shoot-em-up brown and grey but we are furnished with some colours of nu-earth, so it is very nice to look at aswell.
So all in all a pretty fun game with some control issues, oh and easy mode really is easy, just wait until you can un-lock massacre mode bwahahahaha
