Hi!
I've tried several times some tactical movment (covering and running) with group of players or my friends, but we have almost always failed. I think it fails because of the covering fire. If you fire randomly at the enemy, it woun't effect him and I think its because he woun't get feared.
My idea is to aim more tactical gameplay.
It's just a idea so no hates :)
I'm really sorry abot my terrible English.
