It's not that it's bad, its that games like it and better, came out before it, and people see it as a "rip off" of CSS and all those other fps shooters.
It is free,. to Play, to spend money is your own option on clothes and guns and all that crap.
I mean, for the people who cant afford CSS, or COD4, or any of those games that cost money, (lol)
it is the next best thing, even if it does have its negatives and defects.
