we all have our own way of playin this game..some camp, some run..but it definitely takes more skills to run and gun.
run and gun - you need to be 10 times more alert while running and gunning..lookin out for campers,snipers,aim @target and shoot,duck for cover,flank,kill...it's what makes playing first person shooters interesting..at the same time,ur using ur brains,hand-eye co-ordination,reflexes etc...
camping - find a spot,wait........... for unsuspecting passers-by and shoot(even 5 yr olds can do it)..
