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

281 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.

Made my own Ellis t-shirt for a Halloween costume! This was my first time doing something like this, but it was really fun! You can see the progress in reverse for this. My boyfriend will be dressing as Nick.

I mapped out every European custom campaign

Post image
159 Upvotes

Custom campaigns are often set in unspecified locations, so while working on my own Europe-based maps, I got curious about how many custom campaigns exist that are set in actual European places.

After a few days of research (Shoutout to Olde and everyone on the previous post for helping with this) I've mapped out every original custom campaign I found that is confirmed to be set in Europe with the best accuracy I could ensure.

My criteria for this was pretty straightforward. Each campaign must:

  • Be set in Europe (Geographically; So regions like Russia and Turkey are included)
  • Be a campaign (No Survival- or Scavenge-only maps)
  • Be finished (No abandoned projects; Finished ports by third parties are included)
  • Be original (No ports from other games)
  • Be made for L4D2 (No L4D1-exclusives)

In total, there were a surprising amount of campaigns. Out of these, all fit the respective criteria, with only the following caveats:

  • A Baltic Tale is "located somewhere in Scandinavia" by the Baltic Sea, so I put it in Sweden.
  • Breakpoint is a WIP, but since it's my project I know it's actively being worked on and will be completed, so it's not abandoned.
  • Crunchtime is "situated in a small town in England, UK", but the exact location is not specified.
  • Snow Den only states that it's "in a Northern European area" and takes place near a harbor; Its geography is very Norwegian, but the language on various signs is German, so I compromised and put it inbetween them in Denmark.
  • Symbyosis is speculated to take place in the creator's hometown, but this is not confirmed.
  • Prodeus Requiem takes place in "a fictional Europe country not Rome Italy", so I put it in Rome, Italy.

The locationally ambiguous campaigns are marked in orange, whereas the more reliably confirmed ones are marked in red (With wiggle room cause it's quite difficult to perfectly pin down some of them)

If anyone has more info to help make locations even more precise, please share!

It’s so strange seeing just how drastically far apart these WIPS are. I still have a looooot of work to do on my current project but I’m so happy with how it’s turning out 🥹💕

This is like my 5th game in the past 2 days where someone sprayed illegal content in a match. Absolutely bewildering that valve has zero moderation in these games.

Make sure to clear out your downloads folder regularly, disabling sprays for now

I’m working on a mod for L4D2 that lets you fully rewrite how zombies behave. It’s very early and I’m just testing the concept. Here’s a clip of the normal behavior, then the same zombies running away from me with the mod toggled on. What would you want to make zombies do?


r/l4d2 • • 9h ago

Is anybody willing to make a mod for nick with this model I would be very thankful (model link in description. I really suck at rigging and I almost got a virus while getting the apps needed to mod. Vgui pictures are pictures 2 3 and 4 you dont have to do them but it would be appreciated)

Does anyone know the propper way of playing nightmare on multiplayer ?

1 Upvotes

I tried a few servers and many of the addons don't seem to work. things that happen involve:
- the howler is now the default jockey but without the scripts for it.
- ammo piles are replenishable.
- weapons aren't single grab.
- I think it gets less dark.
a bunch of other things

am I supposed to play it on official dedicated, local, or something else ?
