I just thought I'd share some gems. Most of these are just skins, models, etc., and nothing that actually changes the game significantly. Just... cosmetic stuff, mostly.

Mods that are a unilateral improvement:
- Springfield M14 (Replaces the hunting rifle with a much prettier rifle more suited to the accuracy and damage output of the hunting rifle.)
- Remington 870 & Marine Magnum Shotguns (Replaces both pump shotguns with similar, but more realistic pump shotguns that are just plain pretty. Subtle change, but improved. Higher res.)
- EpiPen Adrenaline (Real adrenaline/epinephrine brand and design. Higher res, looks better, more authentic.)
- Lifesystems Mountain First Aid (Like above, a real brand, high-res.)
- Lifepak 15 Defibrillator (A more realistic defibrillator that actually has an animated screen with glowing and blinking lights.)
- Detailed Pipe Bomb (Higher res, with animated components.)
- Corn's Well-Rusted Crowbar (A more realistic crowbar. This particular pack includes three to choose from, with varying levels of rust. I prefer the no-rust or low-rust versions.)

Subjective Improvements:
These mods may or may not be your cup of tea. I kind of like them, though.
- Reanimated Desert Eagle (Same Desert Eagle, but now held with two hands.)
- G3 rifle (For anyone who enjoys the performance of the AK-47 but occasionally gets tired of looking at it, this replaces it with a G3 rifle.)
- HK G36C rifle (Replaces the M16 with a G36C, which happens to be my favorite kind of real-life assault rifle, for looks, anyway. Depends on how much you like the M16.)
- IMI Mini-Uzi (Replaces the Uzi and the MAC10 with these tiny, but highly-detailed Uzis. Not something I'd use nonstop, but a nice, fresh change.)
- Beretta M9 pistols (Replaces the standard pistols with Beretta M9s. There are lots of good pistol mods out there, though, so swapping out occasionally is fun.)

Fun Character Mods
- Rorschach replacement for Nick (From the Watchmen. The page currently has no screenshots, but trust me when I tell you it's absolutely amazingly executed. His mask even animates.)
- Officer Francis (Now he really is a cop. Very well done.)
- Stormtrooper Ellis (File under "Why not?")
- SWAT Coach (Want a cop on both survivor teams? This one's actually really well done, too, and isn't just a skin.)
- Coach Jack Skellington (For fans of Nightmare Before Christmas.)
- Solomon Grundy Tank (I haven't gotten to test this yet, but you better believe I will.)

Game-Breaking Mods
- I have made a dual-magnum mod that gives the player the pistols from Hellsing. I'm not really a fan of Hellsing, but I am a fan of huge-ass guns that tear holes in zombies. It has a few bugs, but it's mostly usable. The dual magnums function as a primary weapon, and have a limited ammo pool because of their sheer power. Message me if you want to download and play with it.
- SMG as sidearm (Makes all SMGs into unlimited-use secondary weapons, like pistols.)
