Introduction to Atomcraft

Atomcraft is a unique sandbox game developed by Triplejump, focusing on pixel-based physics and chemistry. The game offers a deep and immersive experience, allowing players to craft, experiment, and automate their way through various challenges. With 118 elements to discover and a wide range of machines to build, Atomcraft is a game for those who love to explore and innovate.

Elements and Materials

Elements are the foundation of Atomcraft's chemistry and crafting systems. Each element has its own properties and can be used to create compounds, machinery, and advanced materials. Here's a breakdown of the different types of materials you'll encounter:

Types of Materials:

  • Ores: Natural deposits found while exploring, used for crafting and smelting.
  • Periodic-Table Elements: 118 elements that can be refined from ores, used in various reactions and crafting.
  • Compounds: Created by combining elements, used in intermediate crafting and advanced reactions.
  • Gases: Gaseous materials, used in chemical reactions and advanced element production.
  • Liquids: Liquid materials, used as reaction inputs and temperature management.
  • Radioactive Materials: Hazardous materials, used in advanced chemistry and difficult production objectives.
  • Unstable Materials: High-energy materials, used in specialized reactions and advanced material production.
  • Processed Materials: Refined ores, separated elements, and completed reactions, used in machine construction, automation, upgrades, and spaceship repairs.

Crafting Recipes and Chemical Reactions

Crafting and chemical reactions are central to Atomcraft's gameplay. Players can create a wide range of items, from basic tools to advanced machinery. Here's an overview of the key aspects:

1

Ore Smelting

Apply controlled heat to raw ores to produce refined materials or separated elements.

2

Element Separation

Processed material is divided into useful outputs based on its properties.

3

Compound Production

Compatible elements are brought together under controlled conditions to create compounds.

4

Gas Processing

Gaseous materials are generated, moved, heated, cooled, or combined during chemical production.

5

Liquid Processing

Liquids are transported into reaction or temperature-control systems and converted into new materials.

6

Catalyst-Assisted Reactions

Catalysts are introduced to enable or improve advanced chemical reactions.

7

Temperature-Controlled Reactions

Heating and cooling stages change material states and determine whether reactions complete successfully.

8

Radioactive and Unstable Production

Advanced reactions create hazardous materials that can damage surrounding machinery.

Machines and Automation

Automation is key to progressing in Atomcraft. Players can build complex systems using conveyors, temperature controls, filters, sensors, wiring, and logic gates. Here's a guide to building better machines:

1

Conveyors

Move ores, elements, compounds, and processed materials between machines.

2

Trapdoors

Open or close material routes and drop items into another processing section.

3

Heaters

Raise material temperatures for smelting, phase changes, and chemical reactions.

4

Coolers

Lower temperatures, stabilize outputs, and support reactions that require cooling.

5

Filters

Separate selected materials from mixed production outputs.

6

Switches and Wiring

Manually activate machinery and carry control signals between connected components.

7

Sensors

Detect conditions in a processing system and trigger automatic responses.

8

Logic Gates

Combine multiple signals and control machines only when specific conditions are met.

Wrench, Weapons, and Upgrades

The right tools and upgrades can significantly impact your progress in Atomcraft. Here's a breakdown of the essential equipment:

Drills

Breaks mineral deposits and collects ores used in crafting, smelting, and chemical production.

Lasers

Provides a more advanced method for cutting or extracting materials during later exploration.

Scanners

Identifies resources, elements, compounds, artifacts, and other important discoveries.

Crowbars

Opens or interacts with blocked containers, structures, wreckage, and exploration objects.

Movement Equipment

Improves travel across the planet, caves, hazardous regions, and space-related areas.

Storage Upgrades

Increases the amount of resources that can be carried.

Weapons

Protects the player from hostile creatures and threats encountered during exploration.

Utility Upgrades

Supports crafting, survival, automation, exploration, and spaceship repair objectives.

Biomes and Exploration

Exploration is a crucial part of Atomcraft, as it allows players to discover new resources and objectives. Here's a guide to the different biomes and their features:

Surface Resource Regions

Starter ores, basic resource deposits, early exploration objectives, accessible crafting materials.

Shallow Cave Layers

Additional ores, cave resource deposits, blocked passages, exploration objects.

Deep Cave Layers

Harder mineral deposits, advanced materials, dangerous creatures, restricted routes.

Artifact Locations

Artifacts, research discoveries, progression-related objects, hidden resources.

Creature Territories

Hostile creatures, combat encounters, protected resource deposits, higher exploration risk.

Space Areas

Space-based exploration, advanced discoveries, rare materials, late-game objectives.

Spaceship Repair and Progression

The crashed spaceship is the central long-term objective in Atomcraft. Here's a guide to the repair process and progression:

1

Inspect the Crash Site

Explore the starting area and identify the crashed spaceship, nearby resources, and initial progression objectives.

2

Gather Starter Resources

Mine accessible ores and collect the basic materials required for early crafting and smelting.

3

Build the First Production Setup

Use smelting, crafting, and chemical systems to convert raw resources into useful materials.

4

Upgrade Extraction and Storage

Improve drills, scanners, storage capacity, and other equipment before traveling farther from the crash site.

5

Explore Deeper Regions

Enter cave layers and advanced regions to find materials unavailable near the starting area.

6

Complete Quests and Discoveries

Finish progression objectives, investigate artifacts, and use newly discovered materials in crafting and reactions.

7

Produce Advanced Repair Materials

Combine mining, smelting, chemistry, and automation to create the resources required by later repair objectives.

8

Complete Spaceship Repairs

Deliver the requested resources and complete the remaining repair objectives on the crashed spaceship.
