This is one of the finest games to be made in the last decade.
Its like The Wind Waker mixed with bits of Metroid Prime and Spliter Cell.
With loads of its own original gameplay chucked in for good measure.
Its very much like an old PC game "Little Big Adventure" (1+2), both in style and gameplay. And fans of one should certainly get the other.
The game is short, but its very replayable due to its non-repedative nature.
You very rarely do the same thing twice, and the diversity is huge.
Racing, shotting, sneaking, solveing puzzles and fighting....and i have even left stuff out of that list.
Quite simply, theres lots that you simply have to do again. Bits so fun you will keep comming back to it.
I'm on my 3rd go though the game right now, trying to get a good score for the internet rankings.
If you like diversity and exploration in your games this is an essiental purchase.
