Pros
Simple And Complicated
Can Smash A Zombie Head With This (Easy to aim, circle form)
Detailed
Cons
I really want to say something bad but I don't see nothing bad.
Easy to aim, easy to break a zombie head.
Something I put together real quick and thought I'd share. This replaces the original L4D2 sniper scope sight with a fading, 'circle,' styled sight.
