Earth ReGen is an incremental factory-building game where players restore a polluted planet by collecting waste and developing recycling systems. The environment initially contains large amounts of rubbish, and the player begins with one volunteer who removes trash manually. As resources accumulate, new machines become available to automate cleanup and process collected materials. There is no character-driven storyline. Instead, the central objective is to transform contaminated land into a functioning environment through industrial development.

Cleaning the Planet and Building Factories

The gameplay begins with manually clearing rubbish from designated areas. Players move the cursor into trash sites and back out to collect waste. Progression introduces machines that require workers, electricity, and materials to operate. A Trash Cleaner needs workforce, while a Recycler processes waste using power. Machines must be connected through compatible sockets, allowing resources to travel between different parts of the factory.

Machines and Resource Management

Earth ReGen focuses on building production networks and maintaining a consistent supply of resources. Players must examine connections and adjust their layouts when equipment stops functioning.

The main gameplay activities include:

•         Collecting rubbish from contaminated areas.
•         Installing machines and connecting their sockets.
•         Producing electricity for automated equipment.
•         Recycling waste into useful materials.
•         Earning money and Clean Index points.
•         Unlocking additional machines and upgrades.
•         Managing workforce and production efficiency.

Clean Index is an important progression resource that unlocks new equipment. Players can also access skill trees to develop their operations.

Weather Effects and Game Progression

The environment changes as contaminated areas are cleaned. Weather conditions influence production: rain doubles tree output but reduces digging efficiency, while storms extinguish fires. These effects require players to monitor their systems and adjust production when necessary.

Earth ReGen uses objectives and unlocks rather than traditional numbered levels. The available demo includes two locations to restore, with a guided progression system explaining the next tasks. Its final objective involves constructing an array at a Grid Foundry. Players can zoom and move around the map, rearrange multiple machines using Shift, and open skill trees with T. Production can also continue while the game is closed, allowing resources to accumulate between sessions.
