Having loved COD 4, I had to buy this, it took some getting used to with getting attacked by dogs in the online play but it is good! I dont think its quite as good as COD 4, but definately worth buying.
I completed the main game in about 3 hours, it didnt seem long at all! The online game is definately better! Its alot like COD 4 but with added bonus of being able to drive tanks! The dogs are annoying if you cant get anywhere high up to avoid them and the noise that the artillery makes is also quite annoying but it is no big deal!
This game is definately worth buying!
