Plasma

Plasma is a 3D engineering sandbox where you design devices and environments from a large collection of components. You can assemble and customize parts, adjusting their size, rotation, and appearance.

Use a visual programming system to define how your creations behave, connecting logic and control to make mechanisms and machines work. The open-ended format lets you choose what to build and experiment with your designs rather than follow a set progression.

Explore creations and populated worlds shared through the Steam Workshop, or publish your own for others to try. The tutorial introduces building and programming, while more complex projects require learning how the available components work together.

Many supplied reviews enjoy the freedom to build a wide range of contraptions and appreciate how visual programming lets them bring those designs to life. Reviewers also value exploring and sharing Workshop creations, and some describe learning engineering or coding concepts through experimentation. Common reservations include a confusing learning curve, the lack of a defined goal, requests for multiplayer, and disappointment that development and updates have stopped.
