STICKY AWARD Outbreak Outreach #1 - 64-bit & SourceMod / Server Hosts

309 Upvotes

Hi, I'm Steve, Legal Producer for Outbreak Team (backup link).

We've been working on 64-bit L4D2 under NDA secrecy for the last 2 years. You can reach us at L4D2Outbreak@gmail.com.

I'm joined by my Valve-Licensed Co-Leads Madison, Liam, and Raymond.

LEGAL DISCLAIMER: We are NOT Valve, we are just devout preservationists, and our Mod will require base L4D2 to be purchased and installed on Steam. L4D2 is Valve's IP and we are just preserving it with extremely minimal, careful changes.

We're finally reaching out because we need your help!

Over the last 2 years (since Nov 2024), we have been very quietly working on a Valve-licensed, fan-made, optional, non-commercial, forever-free 64-bit Mod called Left 4 Dead 2: Outbreak (our not-yet-public but future Steam Store link).

As we've been under NDA for a long time and our Steam Store page is not yet public, please see the FAQ on our outbreak.team website.

Per our FAQ, we are preservationists at heart -- many of us Xbox 360 purists like our Lead Engineer Madison! Madi and I have always envisioned Outbreak as a celebration of Valve's franchise that doesn't forget our L4D1 and Xbox 360 roots.

In deep respect of those roots, Outbreak will never consist of random nonsense changes and everything new will be kept optional FOREVER.

L4D2 is a 17+ year old game, very different from other Source branches, and Source memory management itself still has blood from Quake. On an engine filled with obscure binary formats with physics based off ancient third-party software, upgrading to 64-bit is the furthest thing from doubling a number. Once we actually booted into a map that instantly crashed, it took a year to fix gameplay/visuals to be 1:1 parity with base, and another year after that to achieve respectable backward compatibility with base Workshop addons.

Unfortunately, we only just recently started pursuing MetaMod & SourceMod support, and it breaks our hearts that plugins don't work with Outbreak yet.

As such, we are aiming for day-one SourceMod support as our top priority. We need help from authors of prominent plugins and server hosts who have reach.

If you are a prominent SourceMod plugin author or server host, consider reaching out to L4D2Outbreak@gmail.com -- let us know who you are and what you do!

We appreciate your patience! 128k BSP grid size, native first-person legs, and long-demanded TLS revert options are coming.

See you Outreach #2 -- where we'll play Yama in Mirror World mode!

P.S. Again, our website is Outbreak Team, and our Press & Inquiry email is L4D2Outbreak@gmail.com.

I'm making a 4-player co-op zombie game with its own special infected, but it's round-based like COD Zombies

34 Upvotes

It's called Mortuus. 1 to 4 players, and every run is on a new map. The specials are what I'd most like your take on: the Juggernaut grabs you and throws you, the Lope runs on its arms and launches itself at you, and the Skitter climbs the walls and drops on you from the ceiling.

The demo is free on Steam: https://store.steampowered.com/app/3680170/Mortuus/?utm_source=reddit&utm_campaign=l4d2

Which special/elite would you think would be cool next?

Where can I find this?

Is there a way to get a legitimate digital copy, or am I going to have to take out a bank loan to buy a physical copy? It says you can redeem a code on the store, but I don't know where I would get a code. I really want to play this game with my partner, and my niece ruined my physical disc a number of years ago. I have it on Steam, but my partner only plays on Xbox.

I made L4D2 zombies that only move when you're not looking at them — RotWire (WIP)

234 Upvotes

another little demonstration of RotWire, the visual modding tool i'm making for L4D2 that lets anyone create their own zombie behaviors without knowing how to code

here i'm making Weeping Angels, zombies that freeze when you look at them, but immediately start chasing you again when you look away

the important part is that this isn't a preset behavior i've made, the video shows me creating it from scratch by connecting a few nodes together, and you can use those same nodes to make completely different behaviors, or combine them with other nodes to create things i haven't even thought of

i'm not making a mod that gives zombies a few new behaviors, i'm making a tool that lets YOU decide how zombies behave

still very much a WIP, what would you make? zombies that run from your flashlight? ones that stalk you from a distance?

edit: also, if anyone has any ideas for behaviors or features they'd like to see in RotWire, genuinely let me know! even if you think they're ridiculous or outright impossible, i'd still love to hear them

please don't worry about whether something is technically possible, that's for me to figure out haha. i'm more than happy to try implementing your ideas, and i've already added quite a few things people have suggested

and if there's anything you're curious about or don't understand, feel free to ask! i'm genuinely interested in hearing what people think

How is this old game still full of 15-year-old edge lords?

61 Upvotes

Have been playing this game casually with my brother for a couple of years. Recently dabbled again in versus, and although I enjoy it from time to time, it is indeed super toxic like so many people here know.

Instantly kicking after one mistake is one thing, but what is really annoying to me is the racist, anti-Semitic, and edge-lord behaviour in the chat. Makes me wonder if these guys are also 30 like me but kept the same humour since high school, or if its a complete new generation that does this.

Is there a way to get the DLCs on console.

1 Upvotes

I recently just bought L4D2 on console. I was wondering is there a chance Valve will bring the DLCs back? Would love to play The Passing and have the L4D1 maps as well.

Hi, I’m not sure if this is the right place to ask, but I have an issue—or rather, a question. This keeps appearing every time I open the game console. I have my add-ons disabled, and I’m not sure why this is happening or if it has any impact.
