if you could only have one or the other silencer or full auto which would you choose? tactical advantages? dissadvantages? why?
I think it really does depend on the situation. That being said I think the silencer is generally more advantages than full auto.
Full Auto:
adv- zombies and other close-combat 'targets'
disadv- I'll still want to go semi-auto for any targets even remotely out there because accuracy is so greatly affected even by the lowest recoil weapons. Not to mention the lower efficiency in ammo consumption and noise will eliminate any chance of remaining unnoticed.
suppressor:
adv: With proper tactics, even heavily armed enemies can be eliminated with out detection. Maximum potential for ammo efficiency.
disadv: Accuracy will still be affected noticeably.
Shooting all day with the silencer on one of my 22's is a lot more fun than a few minutes with a full auto. (I keep saying this over and over)
