On Nov 16th, 2004, Valve released a sequel to their most acclaimed franchise Half-Life 2. Debuting their latest engine technology: Source ® - founding the path to innumerous creation of community mods since. The former Zombie Panic Team didn't waste the opportunity and began the work on their sequel, using the Half-Life 2's Source Engine as a base, leading the release of Zombie Panic! Source in Dec 28th, 2007.


Over the past year, we've been doing these official community gamenights on both ZP1 and ZPS with the help of Pikouchu's servers and we thought (people also suggested) making one on the older version too. Therefore, we'd like to celebrate this date with a Zombie Panic Source v2.4 gamenight on Nov 30th!

As always, Pikouchu will provide the community server for us, others are also welcomed to host their own. Be sure to click on "Set a reminder" to be notified, here are the timezones: GMT: 8:00 PM // PDT: 1:00 PM // EDT: 4:00 PM // CDT: 3:00 PM -- Click HERE for a quick install guide of ZPS v2.4 legacy version.

However, there are some important notice to share regarding this build;

This game version still uses/shares the old Source SDK 2007 MP as a base and it's no longer officially supported by the former and current developers. There will be graphical glitches, launch issues or game crashes during your playthrough. Some might experience it while others it will run without a problem.

Pikouchu provided a handful list of known issues and troubleshooting in case you're having those.

We rarely do these official gamenights in high capacity out there in the community, but Pikouchu usually is the one who will occasionally schedule random game events. If you want to gather a group to play together in specific date or to know when the next event is, join his Discord server!



We will see you up ahead!

Hey everyone!

Today, we're bringing some interesting changes to the game focused heavily on weapon balance tweaks, additional entities for mappers, Angelscript improvements, map adjustments, bug fixes as usual and other miscellaneous fixes. Two maps in question, Harvest and Frozenheart, got some deserved love after all this time.

On Harvest, we're letting Survivors go outside of the house again, some heavy optimization work has been done within the map, we've reverted the capture point objective, and made some other tweaks.

• Fixed menu item #0 not being signaled to the server.
  
• Fixed "void OnEntityUsed(CZP_Player@, CBaseEntity@)" being called twice.

• Added the ability to control the spawning of event-related weapons (snowball) in "logic_player_manager".

We'd like to give special thanks to all community members who provided valuable feedback and requested such changes to be present in this patch. We hope to continue doing these community polls in both Discord servers (Debyaka's & SoD's) and Forums to collect more suggestions on what to work next.

Last year we celebrated Half-Life 1's 25th anniversary with a ZP1 gaming event with the community, reaching almost 60 players around three servers hosted by Pikouchu! We noticed some of you couldn't make it or missed the date after it's announcement, therefore we're doing a second part this Summer!

We'll share more details in the future. Until then, join Pikouchu's or ZPS Official Discord servers!

See you there!

On November 19th, 1998, Valve debuted with the release of their first revolutionary shooter Half-Life. Since then, the modding community has released lots of memorable HL1 mods - one of them being the old gem Zombie Panic 1, released on Halloween 2004 by the former Zombie Panic Team.


We'd like to celebrate this special date with a Zombie Panic 1 gaming event on Dec 2nd! Like last time, the community member Pikouchu will provide the dedicated server with 32 slots and many custom maps! We want to thank those who have previously joined us in our first community night event and hopefully we'll see you all again this December! Be sure to click on "Set a reminder" to be notified, but here are the timezones just in case: GMT: 8:00 PM // PDT: 1:00 PM // EDT: 4:00 PM // CDT: 3:00 PM

If this is your first time playing or an old timer who forgot how to set up the mod, Pikouchu created a quick easy guide just for you! You need to have Half-Life 1 installed and follow all the instructions in the following link: https://pikouchu.com/zombie-panic

If you don't have Half-Life 1, then this is the best time to get it for FREE! (until Nov 20th)



See you then!
- Zombie Panic Team

We're releasing a very small patch today, focused mostly on code cleanup, few UI fixes, supershorty reload animation changes and other bugfixes as usual. Full details below:

• Added "CBaseEntity@ CZP_Player.GetInfectedBy()" method which returns the entity that infected this player.
  
• Fixed weapons never calling the "OnEntityUsed" forward.

• Fixed "func_clip_vphysics" broken "start disabled" key/value pair.
  
• Fixed weapons never calling the "OnPlayerUse" output.

• Added the ability to force disable an event by setting it's CVAR override to a negative value.
  
• Optimized the system in general.

• Code optimizations in several places.

• Fixed radio menus always disappearing after 5 seconds (note: the fix is applied only for radio menus created by Angelscript. SourceMod will use it's internal "workaround" to keep the menus displayed more than 5 seconds).
  
• Fixed the annoying "Loading..." dialog taking the entire screen (rare on Windows, frequently on Linux).
  
• Fixed uncloseable radio menus created by Angelscript.

• [Super Shorty] Changed the starting reload sequence to insert a buckshot straight away.

We're shipping a small patch today containing game performance tweaks, client and server crash fixes, game rules changes for server admins/mods, minor weapon adjustments, and other bugfixes as usual.

• Added an exception for basic administrators (and higher privileges) to the anti-Zombie skipping system. This allows said administrators to switch from game to Spectators team in order to spectate players with bad behavior. Servers powered by SourceMod are required if not done already to "copy" their "admin. list" to ZPS's administration system in order for this to work. ZPS does not read SourceMod's admin lists.
  
• Added "silence" and "unsilence" commands (shortcut to gag and mute at the same time).
  
• Fixed AFK checker kicking players instead of moving them to the lobby.

• Added "bool CZP_Player.IsSilenced()" and "CZP_Player.SetSilenced(bool)" methods.
  
• Fixed "CZP_Player.StripWeapon" leaving "ghost" weapons world models on player models.
  
• Removed the deprecated "string CZP_Player.GrabTeamSpawn()" and "Engine.ExtendGame" methods.

• Changed Survivors walking animation speed. This is an attempt to fix the "drifting feet effect".

• Potential fix for the rare no HUD issue.

• Added a hardcoded proximity check to spawn points that use "line of sight" checks.
  
• Fixed buttons that emit sparks spamming sound precache errors in the console.
  
• Fixed incorrect line of sight checks for spawn points that use this mode.
  
• Fixed rare crash involving "trigger_escape" and rage-quitters.
  
• Reworked capture point entity in order to fix glitch where constantly going in and out of the capture zone would make the capture itself faster.

• Reworked how inventory weight is calculated (no changes to values/behavior) in order to improve performance and support for custom Angelscript/SourceMod plugins.
  
• Reworked how player's USE key is handled (no changes to values/behavior) in order to fix a crash.

• Fixed mistakes in some French sentences related to Shreddingfield.

• [Shreddingfield] Cleaned and optimized Angelscript scripts.
  
• [Shreddingfield] Fixed objectives not being "registered" (they were not visible in objectives list panel and on phone).
  
• [Shreddingfield] Fixed objectives text being hardcoded instead of being localized.
  
• [Shreddingfield] Fixed some broken spawn points.
  
• [Subway] Moved the Zombie spawn in the warehouse's staircase to somewhere else.

• Fixed invisible radio prop in Frozenheart and Harvest.

• Removed "Worker" badge.

• Fixed crash related to players trying to switch to the phone if something removed it from their inventory.
  
• Fixed crash related to player movement.
  
• Removed several Half-Life 1/2: DeathMatch CVARs that are not used by ZPS.
  
• Reworked "sv_cheats" handling (no behavior change, just technical stuff).

• Fixed "Carrier has spotted a Survivor" sound cue not being played to nearby Zombies.

• Added player's eyes position in the debugging overlay (it's the number between parenthesis at the origin row).
  
• Added "silence" and "unsilence" commands to the context menu in player list dialog.

• Added "silence" vote type to the "callvote" command.

• [Carrier & Zombie arms] Removed weight values when displaying on zps_debug command.
  
• [Magnum] Reverted the recoil decay value to the same one used in v3.2.4.
  
• [Winchester] Slightly increased the damage multipliers (bodyshot/limbs only).

We hope you had a great 2022 and have been enjoying the v3.2.5 update so far! Today we'd like to commemorate a special day (12-28-2022) when ZPS turned 15 years old! What started as a simple HL2 modification, ported to a standalone game and now we have a sequel in the works! A huge milestone for an old Source mod still being played and supported by many!



We want to give special thanks to ALL who have been with us along the way, supporting this game in every way possible by hosting servers, creating custom content, playing with friends and inviting new people!

There's also another big milestone that this community achieved a few weeks ago. The Official Zombie Panic Source Survival Guide, created on Youtube by SFM artist McVee back in 2008, has reached over 1 million views! We hope this guide has been a great help keeping you all safe from danger and pressing the right key to PANIC!



Those were some good times... Now, let's go back to the present because we have some interesting events happening within the community that we think you should be aware of!


Throughout 2023, we'll have a series of community tournaments run by ZPS content creator Debyaka, where players will play through a pool of community-made maps fighting for the top 10 and for prizes! The series will be totally free to enter and will also be streamed on his YouTube channel! More info below!



All matches will occur monthly in the "SuperConker's Treehouse Reloaded" community server.

We may also have other free community tournaments throughout the year being run by different members in our ZPS Hub Forums, so be sure to check them out once in a while.


One thing the community has been requesting a lot is a ZP1 gaming night where players can download the first game from 2004 and hang out! Therefore, we'll be planning to schedule an official ZP1 gaming event with our own Pikouchu hosting the server. More details will be shared in a future announcement!

See you later!

• [Inoculator HUD] Moved it closer to the crosshair to make it more visible.
  
• [Player list dialog] Added a way to copy names and Steam IDs to your system's clipboard in the menu (right click on a client). Note that you cannot copy Steam IDs of bots or SourceTV.

zpo_shreddingfield

• Added breakable glowing materials for the boards over the Playground Zombie spawn doorway.
  
• Added "info_player_start" as a fail safe if there's no available Zombie spawn points which gets teleported around for different objectives.
  
• Adjusted Zombie spawn management to hopefully prevent spawns from breaking sometime around Parking Lot objectives.

• Potential fix for various hit registration issues related to hit boxes and collision boxes.

• Fixed AFK checker not ignoring clients during their connection process.
  
• Fixed crash related to score history (used to determine assists).
  
• Fixed crash when force infecting a Survivor.
  
• Fixed crash when picking up barricade plank as ammo.
  
• Fixed crash when trying to respawn a Zombie while a Carrier is roaring and no valid Zombie spawn was available.
  
• Removed Half-Life 2, Half-Life 2 Xbox Live Rich Presence (used in the Xbox 360 port of The Orange Box) and Portal chapters/challenges systems.

• Fixed "bad ragdoll" messages preventing ragdolls to spawn.

• Updated FGDs to match entity changes described here.

• Removed Half-Life 2's "inventory history" panel (ammo pickup, item pickup, ammo denied).

• Added "sv_zps_spectators_alltalk [0/1]" (0 by default) server CVAR. If enabled, Spectators can speak to and hear others teams, this applies to the opposite direction as well. The other teams still have their restriction of "team only talking" (Survivors can't speak to and hear Zombies same in the other way). In order for this to work, "all talk" must be disabled ("sv_alltalk 0") otherwise it won't do anything.

• [Magnum] Fixed "recoil skip" glitch.
  
• [Phone] Potential crash fix when deploying it in certain custom maps.
