I’d never ever forget the first time when I played this game about two years ago, and I can personally vouch that it is one of the best FPS games I’ve played so far.
The concept is pretty simple. Shoot the terrorists and save the nation, from the bomb scenarios and rescue the hostages the terrorists have taken. The arsenal this game provides is pretty amazing and graphics and sound quality makes it an even better experience.
There are about 45 different locations to play and have fun in, even more( if you can download additional maps). Controls are pretty simple and very easily adaptable. The radio messages even make playing with bots just as fun.
Missions are good, and they get tougher as you progress through the game. if you are looking to let off some steam, this is your game, if you feeling annoyed, this is your game and if you just wanna have fun, then this is definitely the game you should play.
(PS: Do try the Night Hawk .50C and Maverick m4A1 Carbine, it works for most of the stages.)
