Free games aren't normally good. This one isn't much of an exception, the score is compared to other free games.
Gameplay:
The gameplay is very fun and addicting. Its nothing of amazing quality, in fact the quality is rather low. If you want to do well, best strategy is to keep moving, like many games. This game is ruled by snipers, which means you should be different. Side note: this game is only fun until you get higher than a 2.4 kdr. after that you can't play anyone who is any good and it loses its charm. You don't get any really decent guns for scopes until like 15 ranks in. This is annoying, but once you do reach the m416 you should be able to destroy. This game is ruled by snipers like I said, but the gods of this game are the people who spend hundreds of dollars buying in game stuff. its stupid for a free game to have so many people with overpowered weapons that they bought. the other big problem with this game is that hackers abound. Its not as bad when you get to higher ranks and play on the higher ranked servers, but when you are just starting you will see hackers everywhere.
Graphics: not great, better than crossfire, not as good as ava
Conclusion: if you have a spare hour or too and want some free fps action, this is the best free fps I have seen. But if you want a real game, go buy something decent, don't waste your time on this game.
