What the developers have to say:

Why Early Access?

“plexum is a systems-driven game that benefits heavily from iteration and player feedback. Early Access allows me to refine its mechanics, balance progression, and expand its content based on how players interact with the core systems.”

Approximately how long will this game be in Early Access?

“I expect plexum to remain in Early Access for up to 12 months, depending on the pace of development and community feedback.”

How is the full version planned to differ from the Early Access version?

“The full version is planned to expand on plexum's existing systems, introducing additional planets, resources, production capabilities, automation options, and deeper progression.

I also plan to expand the interplanetary infrastructure, allowing players to develop increasingly complex production and logistics networks. Existing mechanics will continue to be refined and balanced based on feedback gathered during Early Access.”

What is the current state of the Early Access version?

“The current version of plexum allows players to explore procedurally generated planets, gather resources through mining and automated extraction, craft tools and equipment, and construct foundations and production facilities, including sealed factories.

Players can establish manufacturing and storage systems, configure production processes, and develop their infrastructure as they progress through the available resources and technologies. Vehicles and machines have also recently been added.

The game prioritizes functional gameplay systems and progression. Visual effects, audio and other presentation elements are still being developed and will continue to evolve throughout Early Access.
Several tools already have animations, ambient audio has also been added. Both are still subject to change.”

Will the game be priced differently during and after Early Access?

“The price of plexum will increase as new content and features are added during Early Access and as the game approaches full release.”

How are you planning on involving the Community in your development process?

“Community feedback will play an important role in shaping plexum throughout Early Access.

I plan to gather feedback through Steam discussions and other community channels, using player experiences and suggestions to guide development. This includes balancing progression, improving existing systems, identifying areas that need attention, and deciding where additional content and features would benefit the game.

I want players to have an opportunity to influence how plexum develops, rather than simply receiving updates without being part of the process.”

About This Game

Preface

Out of nowhere, a mysterious alien ship shows up and for some reason has set its sights on you. You don't yet know that it is a seed ship, something sent out by an ancient civilization to terraform planets to their liking. It operates on a completely different level than anything you know. It has its own sense of time. Its own sense of space... or lack thereof. 

The ship sends out a drone, which comes closer than you'd want it to, and you're given a task: collect corn and apples. The reasons for it don't really matter. What matters is that you don't seem to have much of a choice. You have your objectives. You have your instructions. All you can do is follow them.

A week in the life of the caretaker... (Don't worry, it doesn't actually take a week!)

Day 1 - I found myself captured by a mysterious technological marvel, carrying me to another planet. It expects me to carry out a few tasks: exploring the planet it took me to, gathering from the terrain, looking for ores, and trees. So far I've found 8 different ores, and that's just on the surface. There's no telling what I'd find when I'm strong enough to go into the terrain.

Day 2 - I have been given blueprints to make all sorts of... tools. That's what the ship calls them. To me they're just simple machines. They're making what I can make myself, just seemingly more efficient, especially when they're inside a factory. I've been able to double production, compared to crafting it myself, and there's a bunch of tools that make completely different items than I can make. It's obvious automation is the way to go.

Day 3 - I've come across some blueprints to make all sorts of vehicle related items: depots, roads, road stops. They should come in handy when I'm going to connect my factories. For some reason, I'm only able to make small factories. I believe it has something to do with the curvature of the planets. The ship didn't give me any decent answer. Just something about a terraforming job it's performing.

Day 4 - I've been noticing my jumps are becoming less high. This planet's gravity seems to be affected by whatever that ship is doing. Some tools that I was able to freely place outside now seem to have issues, so I've had to start putting things inside the factories. Apparently they seal and have a stable environment. Who knew?

Day 5 - The ship notified me, on several occasions, apparently, that it's performing a terraforming job. I... I don't think I have much time on this planet anymore. I'm not sure what's going to happen to me when the ship leaves. Is it going to take me with it? What about all the stuff I put down? I just don't know.

Day 7 - Can't talk much. Apparently we're not on this planet for long. Gotta make sure I fill the miner and woodcutter as much as possible. 

What is plexum, really?

plexum is a 3D, third-person planetary exploration, resource-management, building and automation game where you play as a caretaker, travelling from one procedurally generated planet to the next.

Gather and process different types of ores and resources, and craft them into increasingly complex tools, machines and materials.

Construct modular sealed factories to keep your tools and machines safe from planetary conditions, while automating production, establishing resource networks and developing your operation while managing the time available on each planet.

The current content offers a few dozen hours of gameplay, depending on how you approach each planet and develop your operation.

  • 200+ item types

  • 40+ placeable objects

  • 37 mineable ore types

  • modular factories

  • procedurally generated planets

  • environmental conditions

  • resource processing and manufacturing

  • automation and production chains

  • farming, mining, woodcutting, metalworking and crafting

  • planetary resource networking
