Sachys: Avoid the "lets play" videos - remember Akhmed is a marauder trained in engineering primarily but has evidently done some kind of special missions in regards to that, restart and make sure his skills reflect that.
Cyraxpt: You're talking about the skills? I used some points in aiming, sniper (for later), Enginnering (to unlock stuff), medicine, camuflage and strenght (to carry more stuff), i think it's well balanced.
...and (SPOILER) melee isnt worth it unless desperately out of ammo (that should NEVER happen).
Cyraxpt: Well, it's more of trying to kill the enemy without the rest knowing, a shotgun blast would alert them, no? Besides, my problem was that the guy was in the next corner, i had to go melee since the first to hit will stun the other.
Good choices on skills, your approach is all wrong! Rethink it (sorry, dont wanna give out any more spoilers).
