A collection of some Workshop Items for Left 4 Dead 2 that I highly recommend. Most of everything in here is all serious rather than being goofy or funny. It mostly consists of Graphical improvement addons. As well as a link to another collection featuring an INCREDIBLE set of HQ weapon models (Made by QUERENTIN). Among them are also some new blood/corpse rag doll effects. There are also 3 custom campaigns in this collection as well.

You'll find "The Division" survivor model re-skins in "The Division" collection (linked at the very bottom) as I feel it gives the characters a much more serious and wicked/tactical look.

If the Division is something you're not really into, I also have a couple of basic reskin addons within this collection that doesn't alter too much of their original look, but makes them look a lot better. A collection is linked in the bottom with more choices for survivor looks, except for Francis and Louis, they only have the one.

Be sure you read the descriptions of the addons BEFORE you use them! Some of these addons do have conflicts as they edit the same things. (The PSG-1 for example replaces the military sniper, but so does the G36 Improved Model addon, so they'll obviously conflict.) Be sure to read the descriptions of all the addons you want to download so you understand what works and what doesn't.

There are also some addons on this list that will say they are "conflicting". To be specific the [Ammo Reborn] addons, they may say they're conflicting but they are actually okay. You don't have to worry about those two addons when they say they conflict. They still work perfectly.
