I don’t even… understand? I think it’s pretty obvious silencers, forward grips, ergonomic grips and recoil stocks are stock standard no brainer installs in every assault rifle you ever intend to use unless you want something exotic like a folding stock. The less recoil you have, the less you have to re-aim after every semi-auto shot after all.
Because you walked down the stairs in a prison and ended up next to a zombie hulk and his friend the zombie necromancer (and they both need to die fast)?
Or insert situation x where you have multiple dangerous zombies approaching faster than you can kill them without reloading and at least one will get in cqc range?
Or a zombie wrestler pulls you next to him during a night raid?
I could go on but I think it’s again pretty obvious you’re not always in control of your engagement range.
Well… unless you debug 30 all skills and use teleport so you can fire full auto, without gun mods, using a high recoil rifle from what is nearly sniper rifle range in cataclysm.
