--UPDATES--

I made it like the recoil from Left 4 Dead, though it differs a little bit, and reloading sounds do play and the models have been fixed, and many more.

Today, I made the the recoil much more similar to the recoil in L4D, and added a new gun - the S.M.G.!

On the 12h of October - I re-overhauled the base much more, and it's almost but not quite like the in-game L4D weapons.

On the 13th of the same month, I fixed a few things.

On the 30th of the same month, I made the recoil more like L4D's and fixed the world model of the Silenced S.M.G.

On the 4th of November, I fixed the Silenced SMG's model (again) and renamed the guns to their real-life ones.

On the 1st of December, but I fixed a bug with the melee attack, and you can now hold down the secondary attack key to melee (why not?) and I also had new model movement for the guns, and a few tweaks to the former as well, and placed them in the new category, and reduced file size.

On the 4th of December, I removed the model movement (because it was getting in the way), and I reduced the recoil to a balanced amount,
And I split the category of the Left 4 Dead 2 guns because I thought "If there are L4D 2 weapons included, why not split them to a seperate category?" You can find them in the "Left 4 Dead 2 SWEPs Fix" category. And I reduced the File Size!
