Genterra

Get Genterra in Early Access on Steam and shape the game as it's being developed!

Earth is failing. The Genterra Corporation has one way to save what's left of humanity: a rescue rocket built off-world, fueled by automated factories scattered across four planets. You are the Architect, the corporation's remote operator. You never set foot on these worlds. You deploy buildings, route logistics, configure recipes, and scale entire supply chains from a terminal back on Earth, with ARIA, your sarcastic AI supervisor, reporting on your every move.

Each planet has its own resources, its own hazards, and its own mechanical identity. What works on the first world will not work on the next. The early game is mining, smelting, and learning the systems. The mid game is research, expansion, and orbital dispatch. The late game is multi-planet logistics and the launch that gets humanity off Earth.

About this demo

This is the free demo of Genterra. It includes:

• All of Terra Prime, the first planet: the full tech tree, from your first extractor to orbital dispatch.
• The first half of Terra Mare, the ocean world: brine chemistry, a full fluid and pipe network, and research up through Fluid Bottling.
• Browser saves: manual saves, autosaves, and quicksaves persist right here in your browser. No account needed.

The full game spans four planets, each with its own biome and core mechanic. If the demo hooks you, wishlist or grab it on Steam.

Features

• Cell-based factory logistics: Lay belts tile by tile. Stack two lines through belt bridges. Manifold with splitters and mergers.
• Deep recipe chains: Ore to ingots to plates to frames to circuits to rockets. Extractors, smelters, constructors, compounders, and compilers feed a tree that gets stranger and harder the deeper you go.
• Multi-planet progression: Complete one world's foundation protocol, dispatch a research rocket, and unlock the next planet. Each world brings new resources, harder recipes, and a fresh blank canvas.
• Research-gated tech tree: Buildings, belt tiers, pipe tiers, and entire categories unlock through a tree you fund with the items your factory produces.
• Copy, paste, stamp: Design one manifold the right way, then duplicate it across the map: bridges, splitters, mergers, and belts included.
• Power as a real constraint: Coal plants smoke, solar arrays gather dust, and kilowatt budgets actually bite. Plan your grid or watch the factory idle.
• Objectives and deployment checklists: Always one clear next goal, never a hand-holding tutorial.
• Per-building upgrades: Spend bits to boost extractors, smelters, and assemblers individually. Tune your bottlenecks instead of replacing them.
• Save anywhere: Multiple named save slots with thumbnails. Autosave. Quicksave with one key.
• Keyboard-first workflow: Number-row building selection. WASD camera. R to rotate. Box-select with Ctrl. The whole loop is built for hands-on-keyboard play.
