... but it's not as "free roam" as they would have you believe.
The game itself is still brilliant - great fun being Iron Man, battling the hordes of enemies. I must admit that the default controls can be quite fiddly - at first the camera goes haywire while you get used to the melee combat control (shake the Wii-mote, which also controls the camera). Once you get used to that and the combined "Wii-mote and stick flight control" it's a blast.
Admittedly, there are options to change the controls, but I haven't tried yet - I'm happy as they are.
The bashing bigger enemies is fantastic - I was pulling turrets off tanks and smashing them to bits for hours last night.
Once you master it all, the game is, overall, amazing. The only let down (hence 4 stars) is the "free roam" - you get free roam within the "battle area", but outside of that is either a scripted mission, or a cutscene taking you to the action.
My only other complaint is the 'upgrades' system. In all honesty, I didn't pay much attention to the manual so it may explain things in there, but I found the upgrades confusing to obtain & use. Mind you, once I had the Repulsors, small missiles & minigun, I was quite happy - then I just needed to find more ammo...
Still a smashing good game though - can't wait to get home from work... :D
Oh, and if the controls are annoying you, try start the game on 'easy' difficulty and practice with them. Once mastered, moving up the difficulty makes the game much more intense - but nowhere near as frustrating as jumping right in!
As with any new game - just give it some time and, more importantly, patience!
