Duncan Shooter OPS Shooter Action Game. Destroy all enemies of the Squad brothers! Defeat the terrorists in this amazing shooting game. Take up arms and face dangerous challenges ahead.

There are many classes and you can unlock more while playing together. As you think, the idea is the same - don't shoot everything.

Since different enemy attack patterns are different, it is better to fight one at a time. But if there are more than a few on the screen, the bullets will pop out from all angles.
