Enter the ambient world of Osmos: elegant, physics-based gameplay, dreamlike visuals, and a minimalist, electronic soundtrack. Your objective is to grow by absorbing other motes. Propel yourself by ejecting matter behind you. But be wise: ejecting matter also shrinks you. Relax; good things come to those who wait. Progress from serenely ambient levels into varied and challenging worlds. Confront attractors, repulsors, and intelligent motes with similar abilities and goals as you. It is 100% DRM and region free, and features procedural generation (play random versions of any level) and an electronic soundtrack by Loscil, Gas/High Skies, Julien Neto, Biosphere, and more.
