Left4Dead2 Visuals Multihack

[Lorian]

you can do something much more broken, just use speedhack on a value like 30 + fast switch, when you change weapon you will shoot 20-30 bullets in a very short time, with another speedhack you can shoot 40-50 bullets. If you create a macro for this, the result will be quite fun

what key to press?

just hold down M1 all the time while your fast weapon switch macro does the rest
