This game is a fast-paced FPS which can be described as a semi-simulator. They've gone lengths to make sure it has enough realism to feel good, but not too much for the less hardcore players out there. Crosshair is a history in this game, you will die to a well placed bullet to the head.
Playing as a team is recommended, as you'll need some tactics to break enemy defenses. It's fun and intense and it's one of those games that do well playing with buddies!
Here's some quick and dirty sniper action!
