Plainly put the game is bad..
Graphics: Horribly old. The graphics don't look a bit realistic or good at all. Gun models look ok but everything else includes bad textures. There's also a load of visual glitches that impede gameplay.
Gameplay: Yes it follows an MMO like Counter Strike formula. You buy weapons out of game rooms and in lobbies and you earn money by killing. You get ranks by...killing again. Money is used to buy new weapons and ranks... well it shows how much you played. The maps look boring and lag even though the game hardly need's a PC to run with the ugly visuals. You also have a massive amount of glitches that players abuse. Speaking of which the playerbase is horrible. Problem is a fault of free games in which a majority of the players are younger children who have ego's the size of an elephant. Also the game lacks in terms of weapons. Not many of them are even practical since the game is absolutely glitchy. Even the hit detection is bogus. You get a white flash on the opponents body as an indication you hit them. Probably a replacement instead of blood.
Sound: Gun's sound horribly fake and more like airsofts on drugs... there are no bullet casings or decals sounds.
This game is not worth your money but if your bored and looking for a FREE game to play it might be worth something to the rest stick to buying your games.
