v3.1 Development Update - 10 Years on Steam!

We're back with another developer update to reveal more upcoming content from the unstable build, including a special day celebrating 10 Years of Zombie Panic! Source on Steam!

Mod's Backstory
Zombie Panic! Source was initially released on Dec 28, 2007 via ModDB page as a Half-Life 2's modification beta. Back then, you were required to own any Source game to play the mod. Valve then opened a new door for mods to be delivered through the Steam platform on Oct 3, 2008. Five of these mods, including ZPS, were selected to be integrated using Steamworks Distribution, which helps streamline the delivery, installation, and update process.



It also consists of features like Steam Achievements, Steam Workshop, anti-cheat technology, management of user-generated content, etc. Getting Steam'd was a huge step to deliver faster updates and get connected with our community even more. We're very thankful for Valve developing such a great tool for the gaming platform.

To celebrate this memorable day, we've gathered exciting news regarding v3.1's development that is ready to be shown to the public!


How things are looking
We're very glad to retrieve two old melee concept weapons from the grave: the Tennis Racket and a Broom! These will be available in the unstable build for public playtesting before v3.1 public release. We'll need your help in providing feedback and ideas to adjust them for being viable in melee combat in the future. If you're thinking that we will only add melee weapons from now on, well, don't lose hope! While we're not yet ready to show them off to the public, take heart in that we have some ranged weapons that we're working on.



We're also pleased to announce the official unveiling of the Biotec facelift! Casei has given the facility a more high-tech, corporate look while retaining the essential classic gameplay which you've come to know and love. There are brand new 3D props by both Darb Dude and Ratboy, new particle effects by Dr.Vodker, new areas with better textures and decals, lighting improvements, and general bug fixes!

With these upgrades being made, we're aiming to distribute the same devotion to our other stock maps imploring for improvements and fixes. Asylum redux and Biotec editions are just the beginning of a much longer evaluation and update process. This is a long-term goal for the mapping team, but it's also a delicate process that needs careful attention to balance and detail, and we hope the results are as pleasing as Biotec's, as seen below:





Feed-O-Meter Adjustments
We've decided to make a couple of improvements to the Feed-O-Meter's usage and Berserk mode. The Feed-O-Meter will now auto regenerate itself when not in use. The regeneration process is very slow and you still should use your feed bar wisely. The Berzerk, on the other hand, now has its own bar separated from the normal Feed-O-Meter bar. This will make the zombie's life easier while allowing them to manage which feature they would like to use without affecting or wasting a single berzerk bar while lunging. The Berzerk function remains untouched beyond that.



This is a heavily experimental change that will require a long period of testing to assure it's well balanced and fair for both teams.

Zombie Teammates Glow
An additional zombie feature has also been added to improve the team's communication and create better tactical ambushes against the survivors. Zombies will be able to see their teammates glowing through nearby walls, but with a minimal range that is more limited when compared to the Carrier's roar glow - without consuming one Feed-O-Meter bar.

Upgraded Voice Menu
We've improved our voice wheel menu system, based on Left 4 Dead's radial menu, adding one extra survivor line: "Keep Moving!". This was unused content for a long time. All current VO's survivors had this line recorded and ready to use, but the previous team never went further with it.



Sadly, due to the changes in the voice system, we were forced to change our voice menu's default keys, replacing with new code commands, which is why you will have to reset your client configurations in Game Options > Keyboard.

Server Browser Info Box
Finally, we've recreated our entire server browser window from the ground up, designing two different server tabs when searching for a community server. We also implemented one server information box advising newcomers about their first connection to any ZPS server. Hopefully, with this new info box, new players will be aware which type of content they can expect out of that server.



Vanilla servers running pure ZPS gameplay will be displayed in the "Internet" tab, while custom servers running any modified plugins will be relocated to the "Custom Server" tab.

We've exhibited a lot more upcoming content (Linux client support, hitboxes fixed, weapon barricade adjustments, ammo hud changes) created to improve your ZPS experience in our previous announcement. You can check it all out in the news below:

Build Status
We're very excited to get the core functionality of the build into the hands of the community as soon as possible to begin our first public beta playtesting with you all. While not everything will be properly balanced and working at first launch, the unstable build is well-considered "playable" at this moment. Hooray!

Meanwhile, we'll keep scheduling our internal playtesting and start organizing the preparations of our public playtesting. Feel free to join our official Discord server to not miss anything from us and lose the opportunity to opt-in the beta right away!

See you during Halloween,
- Zombie Panic! Development Team

About This Game

Dive into the zombie apocalypse with Zombie Panic! Source: a cooperative, survival-horror first-person-shooter. A fast-paced standalone modification.
Choose your team as the undead or a survivor. Enjoy their unique abilities, weapons, and challenges in this high-paced, action-packed thriller.

The Teams

As a survivor, unlock large arsenals of firearms, explosives and improvised melee weapons. Can you stop the waves of undead? Will you engage the horde head-on, or barricade and fortify while your friends play sniper? If all else fails, Panic! Then run as if your lives depend on it… for they surely do.

As a zombie, you’re free to hunt the living like the rabid beast you are. Feast upon their flesh and unlock your inner berserker. Heightened zombie night-vision gives you the upper hand in dark environments. Infect survivors as the carrier zombie (patient zero), to weaken their defenses, then sadistically watch them turn on each other. Use it all to your advantage to strategics, ambush, conquer and destroy your oblivious living counterparts.

Gamemodes

Zombie Panic! Source hosts a variety of game modes for excellent replayability. Explore the zombie apocalypse with:

  • Survival Mode: Put your ability to scavenge and survive to the test. Easily the top player choice.
  • Objective Mode: You’re on a mission. Whether it’s to escape or defeat the horde, you’d better use your brainz to find those keys, get the power back on, hack that computer, and get to the chopper! Otherwise… I think you know what happens.
  • Hardcore Mode: For experienced zombie connoisseurs, you and your teammates get to enjoy pitting yourselves against extra tough foes, and even rougher odds.
