Skip it if you…

Saves you a refund
  • Players who want direct combat may hit a wall at the matter-ejection movement system.
  • Players who prefer constant fast-paced action may bounce off the deliberate timing and growth mechanics.
  • Players seeking a conventional shooter or runner may find the mote-based structure too abstract.

Our take on Osmos

The bounce point arrives when movement requires sacrificing mass: ejecting matter provides propulsion but also makes the mote smaller. Players who dislike repeated trade-offs between position and growth may hit that system early, before attractors, repulsors, and intelligent opponents add further pressure.

What is Osmos?

Osmos is a physics-based game where growth comes from absorbing other motes.

Movement requires ejecting matter, which also makes the player's mote smaller. Levels progress from ambient stages into more varied and challenging worlds featuring attractors, repulsors, and intelligent motes with similar abilities and goals. Players can slow time to outmaneuver agile opponents or speed it up to increase the challenge. The game contains 47 levels, bonus content, and procedural versions of levels that create random variations. Dreamlike visuals accompany an electronic soundtrack featuring music from Loscil, Gas, High Skies, Julien Neto, Biosphere, and others.

How Osmos plays

01Matter-Based Movement
Propulsion consumes part of the mote, changing its size and its ability to absorb others.
02Environmental Forces
Stages can include attractors, repulsors, and intelligent motes with related abilities and objectives.
03Time Manipulation
Players can slow events for evasive maneuvers or accelerate them to raise the challenge.
04Level Variations
Procedural content creates random versions of levels in addition to the main progression.
