This is not the map update that we promised you guys earlier. This is only a small patch to correct issues and add tweaks to the newly updated stock maps and game files. The next map update is still in the works.

This update will add changes to your cfg files so we recommend backing up your game commands and binds by creating a autoexec.cfg file. A basic on how to do this can be found here. When the update rolls out, replace your own .cfg file to the new one.

Zombie Panic Status

Hello everyone! We hope that you are all enjoying the new update. With the help from you, the community, we have been able to fix a lot of issues with the stock map rotation. An effort that is long overdue.
We understand that there may be some confusion as to who this new development team is, and what we are planning on bringing to the game.

What we're up to?
We are a team of volunteers within the community who reached out to Monochrome, explaining to them that Zombie Panic! Source was in dire of development support, and if they wouldn't be able to support it in the near future, the community should be allowed to update the game on their behalf. Monochrome has agreed to this and the team now has the access necessary to make updates go live. However, our team still lacks access to the source code of ZPS, rendering us unable to make any changes that require coding. Monochrome is working on providing us with the source code. We'd like to return this game to its former glory with fixes, new content and proper engine support whenever possible!

We won't promise you guys updates unless we are absolutely sure that they'll happen. However, we will be doing our best to bring fixes and new content to the game. What we can promise is another maps update, which will bring similar fixes and improvements to the rest of the stock rotation. We can't say when this update will happen but we are working on it. There still exist age-old problems with this game that need to be fixed and we are aware of it. For now, enjoy this first updated half of the maps and some teaser of what's coming up!







Visit our forums!
Another thing that we will be focusing on is active engagement with the community, along with frequent updates about development status - Even if that status may seem dead in the water at times. We feel that communication with the community is crucial which is why we encourage you guys to share your ideas with us on our forums!

So come share your ideas for new features and content for Zombie Panic! Source here!

We check these threads frequently and we do take any idea presented into consideration.

PS: The next update will have some changes on your .cfg files as well as including an additional file called autoexec.cfg, so better do some backup now somewhere and save all your game commands and binds in there when the next update goes live. I've created this basic guide on how to do it:

About This Game

Dive into the zombie apocalypse with Zombie Panic! Source: a cooperative, survival-horror first-person-shooter. One of the most popular Half-Life 2 modifications of all time.
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.
  • Assault Mode: Capture the Point. Points are awarded for completing side objectives, adding to the overall score of the players’ team which in the end decides the victor.

System Requirements

    Minimum: 1.7 GHz Processor, 512MB RAM, DirectX® 8.1 level Graphics Card (Requires support for SSE), Windows® 7 (32/64-bit)/Vista/XP, Mouse, Keyboard, Internet Connection

    Recommended: Pentium 4 processor (3.0GHz, or better), 1GB RAM, DirectX® 9 level Graphics Card, Windows® 7 (32/64-bit)/Vista/XP, Mouse, Keyboard, Internet Connection

This game is turd. Everything about it is ♥♥♥♥. The fact that it is a Half Life 2 mod makes it worse. This game couldn't even be ♥♥♥♥ on it's own. It needed another games help to be a gargantuan piece of human fecal matter. This is also another one of those ♥♥♥♥ leech games that permanently attach itself to your steam account and succle on the teet of I honestly have no ♥♥♥♥ing idea what. Don't ♥♥♥♥ing bother. Go play something else!

This is personally my favourite game, bare in mind I've only played 3.7 hours. Of course I do have an extra 219+ hours on an old account.

The Pro's:
You get very nice people
People help you survive
Tell you how to play if your new
Help you with something you don't know
A very easy/hard game to play (depending on players)
Very simple
Amazing game to play with friends

AND MANY MORE!

The Con's:
You get trollers (rarely)

----------------------------------------------------

Thanks for making this game great, I've known someone with 17k+ hours playing ZPS, amazing!
I'll reach out for the 100+ hours!

Zombie Panic! Source is over all a GREAT game to have fun, and is worth it for a free game.
There's so many PROS but not many CONS, and I'm glad they've started updating it again. It should be an even better game now! And of course, I have 1.8+ hours. But this doesn't mean it's my main. I've had over 220+ hours on an old account!
Keep up the good work.

I'll leave a copy in Russian down below

Zombie Panic! Источник находится над всем большая игра, чтобы получить удовольствие, и стоит для бесплатной игры.
Там так много ПРОФИ, но не так много СВОД, и я рад, что они снова начали его обновления. Он должен быть еще лучше игру сейчас! И, конечно же, у меня есть 1.8+ часов. Но это не значит, что это мое главное. У меня было более 220 + часов на старом счете!
Продолжайте хорошую работу.

Fantastic old Source zombie game. Unfortunatley the community is quite small but they're still kicking strong. Fantastic idea of gameplay with the use of barricades, sharing weapons and ammo, and infected survivors. Great game to play to pass some time, and have some great fun! I mean come on, what can you lose? It's free and takes up practically no harddrive space. 8/10

A game that is very nostalgic to me because its one of the first I've loved. At this point, the game has only two maps, both community made. The original maps are only played on one server that is not usually populated. This game is very good to this day and I highly suggest Contagion as well.
