I'd say that is a generous score, considering the time & effort that went into the game. It's being reported that the game was in development for as little as 6 to 10 months. Those types of tactics should never be supported by anyone.
Had this game been given 2-years, it could have been a great game... But I'm guessing that Activision didn't want to invest any time into the game with the next gen consoles coming out later this year. If gamers wouldn't support this crap by buying their games, then this kind of shenanigans wouldn't happen.
