Alchemos

Alchemos is a single-player action and exploration game set on molecular worlds built from real scientific data. You pilot a Proto-Atomic Shell, an atomic-sized device that collects and combines subatomic particles. As an operator, you explore experimental environments and gather protons, neutrons and electrons to rebuild the Elemental Archives, which have been attacked by mysterious Dark Forces.

Explore molecular worlds

From a laboratory bench overlooking the Experimental Hutch, you remotely control the Proto-Atomic Shell after a sample-changing robot transports it to a selected level. Each environment is created from real-world protein structure data. You begin at one end of a protein chain, collect the particles required for the level, then reach the other end for the shell’s safe extraction.

Face Dark Matter

The Dark Matter forces that attacked the Elemental Archives evolve as you progress, bringing increasing challenges. Dark Atoms develop more sophisticated ways to interrupt your progress when you undergo Fusion with them.

Abilities and upgrades

Discovering elements unlocks abilities for your Proto-Atomic Shell, including jump, dash and quantum tunnel modules to improve movement. A Beta unit lets you interchange between protons and neutrons, while a gamma-ray emitter freezes enemies and the Annihilator lets you fight back against Dark Matter.

You can earn Quarks by completing side objectives and spend them on fully reconfigurable upgrades. These can improve speed and movement, energy regeneration and efficiency, and resistance to radioactivity, among other attributes. You can freely reconfigure upgrades from the main menu at any time.

Levels and leaderboards

Each level has a Steam-friends leaderboard. After beating your best time for a fully completed level, you can challenge your Steam friends to beat it.

Laboratory and presentation

You can unlock interactive ornaments for the laboratory workbench shelf, including a 3-mode Lab Timer, a service bell tuned dynamically to the music and an Albert Einstein Bobblehead. The soundtrack reacts seamlessly to the game state, and the sound effects stay in tune with the music.

Atoms are rendered with custom raymarching, using smoothly joined surfaces without edges or vertices, along with reflections, volumetric fog, soft shadows and dynamic lighting.
