Our take on SpaceChem

Its defining activity is constructing a reactor factory that transforms raw materials into chemical products while meeting production quotas.

What is SpaceChem?

SpaceChem casts players as reactor engineers serving frontier colonies.

The central task is to build factories that convert raw materials into chemical products. Each puzzle requires a design that meets a production quota, while encounters with hostile threats add pressure to the engineering work. Designs can be refined as part of the production process, making factory construction and optimization the core activity. The game includes more than 50 puzzles, an original soundtrack by Evan Le Ny, and 20 achievements. Its setting presents SpaceChem as a major chemical synthesizer, placing the factory-building challenges within a larger frontier-colony context.
