The best Project Zomboid mods for B41 and B42

What are the best Project Zomboid mods? While mods can be applied to most games, there’s something particularly special about sandbox games where it feels like almost anything is possible. Project Zomboid is the perfect example of this, featuring complete game expansion transformations and simple quality-of-life improvements.

Project Zomboid has been out since 2013, but the zombie game has recently rocketed in popularity, with tens of thousands of players returning for the Build 42 update. There are plenty of mods to improve your experience, and modders are already updating their mods for B42. Here are the best Project Zomboid mods available for the survival game right now.

The best Project Zomboid mods in 2025 are:

ORGM Rechambered

Version: B42

While using firearms is usually a quick way for you to become the horde’s next meal, you might not be able to resist after installing the ORGM Rechambered mod. It completely overhauls Zomboid’s guns, with a focus on realism, and it also adds over 100 new firearms for you to get yourself killed with.

Way More Cars

Version: B42

Not only does the brilliantly simple Way More Cars mod provide a larger pool of vehicles to choose from, making finding one that actually runs that much easier, but it also answers a valid question: ‘where did all those zombies come from?’. Creator Gamestamechanic asked just that before making Way More Cars, adding to the mod’s backstory as well as its useful mechanics.

Last Stand Together

Version: B41

The Last Stand Together mod adds multiplayer functionality to the original wave defence mod, letting you set up a game where you and a buddy can sit in a house a try to survive wave after wave of the undead until you eventually succumb. Fun!

Computer

Version: B42

The Computer mod takes the humble PC and turns it into a fully interactive item that can be used to relieve boredom, anxiety, and give you a boost to your mood. Disks spawn all over the map that can be used to install new games to your PC – the computer needs electricity to run, though, so plan ahead and make sure you’ve got enough juice.

Water Pipes

Version: B42

With the inclusion of proper farming, you might want to try automating some of your labor, similar to Stardew Valley. With the Water Pipes mod, you can construct a plumbing system that draws water from lakes, wells, and other sources and uses it to keep your crops hydrated. It can also fill water barrels, so you’ll never be without something refreshing to drink.

Bandits Creator

Version: B42

In an expanded version of Slayer’s Bandits mod, Bandits Creator adds new, hostile human NPCs to Project Zomboid – as if fighting off the undead alone wasn’t bad enough. While Bandits adds basic hostile NPCs, the Bandits Creator mod allows you to allocate traits to these humans, dictating how they try to impact your survival. For example, an electrician will damage your generators, while a mechanic sabotages your car. Plus, you can decide how tough NPCs are, how often they appear, and other such customizable aspects. Slayer is also the creator behind the incredible Week One, further down this list, so you know you’re in good hands.

Project Summer Car

Version: B42

One for the gearheads amongst you, the Project Summer Car mod expands the inner workings of the automobiles in Zomboid, making cars much more of an endeavor to keep running. You can also use the 18 simulated car part types and four fluids (apparently) to customize your post-apocalypse ride, creating your perfect runaround for dodging the undead.

SecretZ Pandemic

Version: B42

A map enhancement mod, SecretZ Pandemic, adds several military checkpoints, outposts, and even a few secret bunkers. Use these to gear up, but be careful of what you may find there, including some additional items that suggest the military may have known a little more than they let on…

Occupation Based Starting Gear

Version: B42

The Occupation Based Starting Gear mod gives each of Zomboid’s starting occupations a different set of gear that is in your inventory when you start a new game. It makes sense that if you’re a police officer, you’d already have your standard issue handgun and a holster, and if you’re a chef, then why wouldn’t you have a can opener in your pocket?

This mod adds a bit of nuance to your initial choice of occupation; you may have opted out of the nurse job on previous runs, but now that it starts with a host of medical supplies? It could be a very shrewd decision indeed.

 

Week One

Version: B42

The stock version of Project Zomboid drops you straight into the zombie apocalypse when you begin the game, but what if you want to see how events unfolded? With the mod installed, your game actually starts seven whole days before the outbreak.

We recently reported on the epic Week One mod by Slayer, and it’s undoubtedly one of our favorites. Of course, Week One isn’t technically canon, but we’re happy to accept it as such if you are.

TV and Radio Reinvented

Version: B42

It might not strike you as one of the most important things to have added to Project Zomboid, but once you have the TV and Radio Reinvented mod installed, you won’t look back.

This mod adds more interactivity and interfaces to the in-game television sets and radios, introducing a new layer of immersion to the sandbox game. So, when your character puts on Life and Living to pick up new skills, you can be entertained at the same time with actual television shows to sit down and watch.

They Knew

Version: B42

Thanks to new medicine types introduced by the They Knew mod, you can heal yourself of the zombie virus, but must do so each time you’re infected. You also have the option to delay your deterioration, giving you longer to find a cure, and there’s also an infection prevention pill that resists infection for 24 hours.

While this already adds some interesting items to the game, the creator has also promised an expanded universe for the mod, with new zombies, items, and a unique NPC trading system. We’ll update you once we hear more about this mod expansion.

Generator Time Remaining

Version: B42

It can be frustrating not knowing just how long your generator fuel is going to last, after all, it’s one of the most important resources you have for survival. The Generator Time Remaining mod helps solve this by adding the days and hours you have left after the percentage.

Unfortunately, the mod doesn’t add the same change for condition, which is arguably just as crucial. Perhaps it will be added in time, but at least the fuel amount gives you a rough idea of when to go out looking for more.

Skateboard!

Version: B42

Not as fast as a car, but infinitely more rad, the Skateboard! mod adds a ridable skateboard to Zomboid so you can get from A to B in style. Amazingly, you can press G to pop an ollie, and if your board gets too damaged, it can even be repaired; A must-have.

Automatic Gates

Version: B41/B42

There are a few Project Zomboid mods that automate gates, and we’ve got ones for B41 and B42 here. Automatic Gate for B41 does just what you’d expect by adding automatic gates. A small but mighty change when you consider the potential death waiting for you outside your car doors.

Automatic Gates for B42 is much the same, giving you the option to flash your car lights to open your gate. Both mods require you to have built the gate for it to work, but it’ll lower your risk of being eaten on your way home. Due to the size of your vehicle, both mods restrict automation to double doors, double metal pole gates, and double metal wire gates.

Ain’t That A Kick In The Head

Version: B41/B42

No longer just a bop by Deano, the Ain’t That A Kick In The Head mod adds a couple of new starting scenarios for your new run, both based on the opening to Fallout New Vegas. The ATAKITH (slightly easier to type) mod spawns you into the world with a bullet wound to the head, with the kicker being that the round is still lodged in your cranium. You need to search for medical supplies, fast.

Vehicle Repair Overhaul

Version: B41/B42

Those PZ mechanics among us surely get frustrated with the lack of options when it comes to fixing up your in-game wagon. Well, that all changes with the immense Vehicle Repair Overhaul mod, which has been designed with actual mechanics and welders in mind.

Fix flat tires, salvage old vehicles for parts, and weld those parts to your motor to fix up your favorite broken-down car. You’ll lose countless hours tinkering away in your garage, but that’s no bad thing. Vehicle Repair Overhaul is available for both B41 and B42, but the salvage option isn’t available in B42 yet.

Braven’s Bicycles

Version: B41

A bicycle might not be your first choice for escaping a zombie horde, but it’s better than your own two feet. The awesome Braven’s Bicycles mod adds a range of bike types, each with its own unique stats, and you can even add a trailer to carry your scavenged resources home. Of course, the benefit of a bike is that it doesn’t need gas or a battery, but peddling does tire you out and leaves you more vulnerable to attacks.

Vanilla Firearms Expansion

Version: B41

Vanilla Firearms Expansion adds a range of new weapons, while also replacing the textures of existing guns to create an overhauled arsenal. Blow zombies away with the likes of the semi-automatic SPAS-12 shotgun, Uzi SMG, or AK-47. New attachments give you alternate ways of kitting out your weapons, including mags with faster reloads and stabilizing bipods.

Perhaps the best addition granted by VFE is its rework of the jamming mechanic. Now, when you clear a jammed firearm, your lost round is returned if the gun is completely unloaded before clearing. The Vanilla Firearms mod is among the community’s favorites for a reason, but it is still restricted to B41. Sadly, a founding creator of the mod passed away in February 2025. While the mod is being updated for B42, this has naturally put progress on hold.

Expanded Helicopter Events

Version: B41

In the vanilla game, a helicopter event takes place towards the beginning of your playthrough, drawing hordes of zombies towards you thanks to its loud sirens. With the Expanded Helicopter Events mod, there are more of these chaotic incidents, including crashed choppers, sirens, and much more.

As one of the community’s favorite mods, Expanded Helicopter Events had to be on our list, but it’s worth noting that it’s only compatible with Build 41 right now. One of the creators, Chuckleberry Finn, has said that they’re planning on updating it for B42.

Unpack

Version: B41

We’re still waiting on this mod to be updated to B42, but it’s so good we can’t leave it off this list for those of you still playing Build 41. The Unpack mod moves and sorts items from your inventory into your home storage, saving you valuable time (and energy) when you return from a long day’s scavenging. It’s a game-changer.

Common Sense

Version: B41

The Common Sense mod adds some quality-of-life changes that make… common sense. Being able to pry doors open with a crowbar, crafting makeshift spears from brooms, and opening cans with knives; these are things we think are fairly plausible, and with this mod, you can do them in Zomboid, too!

Lean & Lie

Version: B42

A simple mod, Lean & Lie adds the functionality to relax on some objects you couldn’t previously. Sometimes you want to stay put, read some books, watch some tv – might as well relax while you’re brushing up on your survival skills.

Rain Wash

Version: B41

The Rain Wash mod adds a small but immersive feature whereby your clothes will slowly become clean if you’re out in the rain. Covered in blood? No problem! Blood will slowly be turned into dirt, and then the dirt will gradually be washed away, provided you remain exposed to the elements. We aren’t sure it’s a replacement for a good wash, but it’ll do in a pinch.

Here Goes The Sun

Version: B42

A lovely little mod that changes up sunrises and sunsets each day. The Here Goes The Sun mod varies the lighting at the start and end of each day so you aren’t seeing the same thing every day of your miserable existence. It changes with the seasons, too, so expect beautifully bright sunrises in summer, and bask in the warm glow of an early autumn sunset.

These are just some of the best Project Zomboid mods we’ve seen, but we’ll be watching out for great ones to add to this list. Whether you’re just getting into the crafting game for the first time or returning for the new build, take a look at how combat is improved in Build 42, among other big changes.
