With your left thumb, you control each movement your character takes on, while with your right thumb you carefully aim your weapon. Each weapon is automatically fired whenever you're aiming properly at an enemy so all you have to do is make sure your aim is good enough not to miss, and that you have the right weapon at hand.
In Combat Assault, you'll find several different scenarios available, even though you won't initially be able to take your pick. Each one gyrates randomly, so you'll get to test each of them, just not whenever you want. When you start out playing you'll only get a single weapon to have on hand, but you'll get to unlock quite a few more as you progress.
Combat Assault is an online FPS that's fun and has excellent visuals. It offers players a straightforward, simple game that'll keep them entertained for a few hours.
