what is better (mk1) ??
Per use, I'd say you'll get more kills with a Granade.
Sentry is used for support but when you are rush type player, grenade is the best for you to use. Much better to upgrade it also for range and damage.
how to trow granade plz help ??!?!?!?
If you play on the ipad press the button on the side of the screen. If you play the computer version press the 1 button on the keyboard.
Mk1 is only good when someone is camping throwing it while the target is moving is usually useless.
Sentries are only good when placed in the correct position on some maps they suck, but otherwise they can mow down enemies or produce cover fire defensively.
