welcome to plexum...

In plexum, you are taken by a mysterious technological marvel and carried across an ever-changing chain of planets.

Extract resources, design efficient production lines, and expand your capabilities — but nothing lasts forever. Each planet is a temporary opportunity, for both you and the marvel, to gather what you need.

As you travel, you’re forced to leave everything you built behind. Not all is lost, however — every system you create feeds into a larger progression, where planning, efficiency, and smart use of resources determine how far you can go.

Ever-changing planets

• Traverse a chain of distinct planets, each with new resources and constraints

• Adapt your production setups to different environments

• No two planets feel the same

Planets introduce hazards such as extreme temperatures, toxic conditions, or unstable ecosystems - requiring you to prepare ahead while making the most of your current opportunity.

Build and optimize systems

• Place machines, connect processes, and create efficient production chains

• Refine layouts to maximize throughput and minimize waste

• Turn raw resources into increasingly complex outputs

Construction follows clear rules: foundations anchor your builds, floors enable expansion, and machines depend on structured setups - you can't just place anything anywhere.

You don't stay

• Progress pulls you forward - whether you're ready or not

• Leave your builds behind as you move to the next planet

• Every decision matters before it's gone

There is no endless optimization - only constant progression. What you build is a means to move forward, not something to perfect forever.

Nothing is wasted

• Systems you build contribute to long-term progression

• Balance short-term efficiency with long-term gain

• Plan ahead to get the most out of every planet

Progress isn't just measured in resources, but in experience - nothing is strictly gated, but pushing forward unprepared comes at a cost.
