Seems some of you are already playing around and uploading videos too!

In addition to it being fun, we also got some great quality reports and data on some bugs we discovered in our playtest. Here is the current known issues:

- My screen is too bright or strange looking upon first launch!
Press Shift + ESC and a console will drop down, then enter "brightness 0;gamma 1" to fix this. HL's config will sometimes interfere and cause mayham, will address in a hotfix.

- Disappearing/weird weapons
When switching PVS (rooms), this issue occurs. We are simply going to have to optimize our networking code more. We'll let know as we tackle this one.

- Grenade Launcher and Tesla don't deal damage!
A simple last minute typo! Will be addressed in a hotfix.

- No Music or Video
We'll have to ship a new binary soon to fix this and a cert bug

- Harpoon Grapple Issues
The alt fire on the Harpoon is a bit finicky, it too will be addressed.

- HUD Elements
We have a few more touches to add to the HUD, we just ran out of time!

And we'll post more as we update and fix things. For now follow us on our socials and see you again soon!


Game Day


Operation Deathmatch Trailer

Ahoy!

Overturn is out now and the play testing is live!

After 12 years, we finally are delivering on our promise to bring you a unique Half-Life experience!

How to join?

Remember, this is not a typical Half-Life mod, it runs on Nuclide!

Keep in mind, this is a playtest, there will be bugs and at worst case a crash.

With that out of the way, here is how to install and play the demo!


Download Overturn Operation Deathmatch - ModDB


How to Play (Operation Deathmatch) - ModDB

If you prefer text-based instructions:

  1. Download Operation Deathmatch

  2. Extract it and copy all the files

  3. Enter your Half-Life folder (typically Steam/steamapps/common/Half-Life) and paste the copied files inside:

    overturn

    valve

    valve_downloads

    valve_hd

    hl.exe

    Overturn_SSLFix.bat (Windows Launcher)

    Overturn_x86.exe (Windows)

    Overturn_x86 (Linux 32-bit)

    Overturn_x64 (Linux 64-bit)

  4. Launch the Overturn binary for your platform. NOTE Windows users please use Overturn_SSLFix.bat!

  5. Setup your controls under "Config", and your player fluff under Multiplayer/Customize. Then, join us under Internet Games or Create Game and host your own! No port forwarding required.

  6. Have fun!

Note: If a desired platform is not here, then you can always try using the FTEQW engine as is, however this is a more manual process, only try this if necessary.

How long?

We'll try to play at least a couple hours, but hang around longer if people are interested!

Socials!

What's in the Update?

As a reminder from our last post:

  • 12 Unique Weapons
  • 8 Stylish Player Models
  • 4 Classic Game Modes (DM, KOTH, CTF, INVASION)
  • 3 Immersive maps
  • Tons of custom sounds and other content
  • Our reverse engineered Source Engine I/O, Spirit of Half-Life (WIP), and idTech 4 decl system

Note: We mistakenly said 13 new weapons last time, this was a typo (but there is a not-in-demo WIP 13th weapon…)

That's all folks!

See you in the Frag Chamber!

BRING YOUR CHAINSAWS!

Follow us on the fediverse!
