Keep reading for an overview of what Build 42 brings to the apocalypse.

What’s Coming in Project Zomboid Build 42?

The latest update aims to make the game more community-oriented. New weapons, professions, and mechanics will allow players to interact in innovative ways and experience new situations.

Weapons

Killing zombies is fun, and more new ways to mow down the undead add a little spice to your gaming experience. With that in mind, a whole host of new weapons will be available in B42. These include a Desert Eagle, a .44 Magnum, and an M14. More new weapons might still be unveiled.

In games like Project Zomboid, one concern for players is a lack of variety in combat. New weapons mean players have to think carefully about strategies. This big update to weapons has already sparked plenty of discussion and updates to PZwiki.

Crafting Mechanics

Crafting is one of the key ways to enjoy playing Project Zomboid. The crafting system is set to change, with players now able to modify a wider range of weapons with exciting upgrades. The developers have promised an “RPG-style” system of development that will allow more customization.

New Professions

Project Zomboid isn’t just about killing hordes of undead. It’s also about trying to survive in a post-apocalyptic world. That means making a living somehow, using one of the many professions available in the game.

New professions will include brewing, stonework, and brewing. There is a lot more to learn about how these professions work, but they promise to allow players to become more self-sufficient. Plenty of new items will be introduced to help these professions function.

These professions have another key benefit. By allowing players to harvest resources from the land itself, rather than scavenging, players can keep their worlds running forever, for as much time as they want. That is, until players succumb to zombie bites.

Other Changes In Build 42

Aside from these major changes, there are a range of smaller improvements that have been made to the game. Although these may not seem as eye-catching, they could still make a huge difference to the game experience for the average player.

Lighting

The lighting for Build 42 is set to change significantly. Instead of emanating from tiles, it will now appear more naturally. Although this is a small change, it should improve the look of the game and help players to feel more immersed in the game world.

Quality of Life Updates

It’s over 10 years since Project Zomboid was released, so older versions of the game sometimes run slowly on newer computers. The new build adds performance updates along with new content, promising fewer bugs and more efficient running, especially in the late game.

Customization Options

More character customization options are coming to the game. Players can make more choices about how their character looks and interacts with the world. It all adds to the replayability value of the game.
