An interesting idea with even more interesting environments
I wouldn't say its the worst game out at all. The game has some unique gameplay aspects with make it an enjoyable break from the normal fps carnage and rts planning.
There are some extremely difficult points in the game to get past which would create a lot of frustration espically given it seems to be aimed at a younger audience it seems a bit on the hard side to finish.
Over all if you are tired of the normal and want to try something else i think you can probably find this in the bargin bin now a days. Its definately one for the kids.
