The game has the classical mechanics of every FPS. You shooter and take down your enemies. The plot is not essential here, it's the fun you get. You're Andrew Sterling, a MI6 agent on a run first and then over your head with "work"
Your primary work here is shooting. And I mean shooting. You kill everything you see.
All right, there's a plot: save the world. That did you expect? You have all sorts of weapons (sadly you can't carry more than two. You must take down tanks or helicopters (that was the most difficult part of this game).
A good shooter for a ten-year old.
