Ladies and gentlemen, I'd like to present to you: Left 4 Dead 2 Essentials (Or Left 4 Dead 2+ if you'd prefer that). A collection full of add-ons that definitively improve Left 4 Dead 2. The FIFTH collection in the "essentials' series" after Garry's Mod Essentials, People Playground Essentials, POSTAL 2 Essentials, and finally Half-Life 2 Essentials, all of which I'd recommend taking a look at if you have any of the aforementioned games (Wait, FIVE? 5 whole collections?!).


Left 4 Dead 2 Essentials is a collection full of add-ons I've found scattered around this workshop that are polished, widely agreeable improvements. These are the kinds of add-ons that are so polished and faithful that a casual wouldn't even notice their inclusion. This collection doesn't aim to rebuild Left 4 Dead 2 from the ground up, overhaul its graphics, or give Zoey jiggle physics; this collection simply aims to build on-top of and refine what was already there, even more than the Last Stand update already did(n't). In other words, the goal of the collection is to enhance Left 4 Dead 2 overall in subtle and faithful fashion. Of course: I wasn't just doing this recklessly. Here's a few priorities that I followed whilst compiling this collection (In-order of importance):

• Nothing outside of what Valve could/would do! So no 4k UHD mods, no memes, none of that. Everything must match the visual fidelity and style of Left 4 Dead 2. Any improvements would be either restored cut content, additional content that fits the style and writing of the game, or fixes. Lots and lots of fixes.
  
• The base mechanics of the game shall not be touched. The goal of Left 4 Dead 2 Essentials is to add or improve, not to simply change. As such, any add-on that interferes with the core gameplay of Left 4 Dead, positively or negatively, is disallowed. Sorry, RNG Object Spawner, you can't make the cut (luv u tho).
  
• No new campaigns. *Everyone* has different tastes when it comes to what they're looking for in a Left 4 Dead 2 campaign, so I'm not gonna bother trying to package anything in. If you really want my recommendation, though, Daybreak certainly isn't a bad start.
  
• Conflicts are handled in a lazy fashion. In-short: If there are no visible errors, there is no conflict. In-long: Add-ons that use the "MST" system to decide whether they're active or not will always "conflict" with other addons that also use the MST system to check those maps, and as this collection as multiple that check for Left 4 Dead 1's campaigns, there are fake conflicts, which I am ignoring.
  
• Buggy, unstable, or immersion-breaking add-ons are not allowed. No crash-happy add-ons, no visual or functional jank, none of that. You should be able to just install and enjoy.
  
• Performance impact is mostly ignored. It's 2025. If your computer is struggling to run vanilla Left 4 Dead 2, then you need to stop trying to play games on your office laptop. My rule of thumb whilst developing this collection is that if my mid-range computer has a noticeable performance impact after adding a single add-on, it'd be removed, so if your computer was built with gaming in-mind and/or is less than 10 years old you should be fine.

Note that this collection has a reliance on Vscript for some of its changes, meaning a small portion of the collection is serverside and therefore won't be present on official dedicated or community dedicated servers. Thus, you can only fully enjoy the collection in singleplayer, or in a local server created using the map [map_name] command for friends-only multiplayer. Sorry, that's just how it is.

For those who'd like to know what they're getting into, I did you the courtesy of listing everything this collection does. Feel free to take a look, and decide for yourself what you like or don't like.

[NOTE: List seen below is also the order of which add-ons are sorted in the collection itself.]

• Improved and expanded UI. A refreshed main menu, a definitively improved add-ons menu, a more responsive and modular HUD, and more.
  
• Minor gameplay enhancements, primarily including vastly improved bot AI. There's some minor improvements in this section, like giving Jockey's a brief pounce sound or messing with doors for minuscule replay variety, but the most essential additions are Competitive-Bots+ and Left 4 Bots 2. In-short: Competitive-Bots+ mostly just tweaks the pre-existing bot AI to make them more responsive and focused, but Left 4 Bots 2 adds a lot of new functionality to the bots, such as scavenging and throwing 'nades, obeying commands, using defibs, and more. For a full list of improvements, see each add-on's workshop page.
  
• Talkative survivors. For being humans, the survivors are surprisingly silent throughout your average campaign. They call out for help, complain about being shot, converse, etc, but they don't typically acknowledge when their allies are in trouble or a major success as often as would be realistic. Or they just say things that don't make sense. This collection changes that with many talker additions that serve to make the survivors feel more alive.
  
• Left 4 Dead 1 campaigns further feel like Left 4 Dead 1. L4D1 and L4D2 are quite different stylistically, and a degree of effort has gone into separating them further in this collection. It's mostly minor, such as UI elements changing to match their L4D1 counterparts, misc material reversions, etc, but the most major (and perhaps divisive?) change has to be giving the Charger, Jockey, and Spitter their own unique model for L4D1 campaigns. If you don't care about the sanctity of your L4D atmosphere, you can skip these add-ons.
  
• Expanded/enhanced effects. Better snow, bloodier, more plentiful gibs, map-specific waters, and more. Left 4 Dead 2's gore was already pretty sophisticated, but now it's even bloodier than ever.
  
• Performance < Gameplay trade-offs. Two add-ons in this section are tweaks that degrade performance in-favor of lower latency and higher visual fidelity, those being [VSCRIPT] Real Time Common Infected and Increased Decal Overlap Limit. If you're on lower-end hardware, it's recommended to skip these two add-ons.
  
• As per usual: Many minor fixes. Some of these are more beneficial than others, like making wandering witches react to being shoved or worker infected react to boomer bile, but a lot of it is minor map fixes and material stuff. Despite how many add-ons are included here at the bottom of the collection, the file size these take up is quite small, so I would not recommend skipping it.
