Play Cosmos Adventures 3 Online

Cosmos Adventures 3 was released as part of the MS-DOS Classic Games collection, though details about its original developer or publisher are scarce. It belongs to that era of platformers where games often felt experimental, built with a mix of ambition and technical constraints that gave them a distinct, sometimes unpredictable, character.

You control a small character, navigating through a series of side-scrolling levels filled with obstacles and enemies. The main goal is to progress from start to finish, avoiding hazards and collecting items along the way. Signature mechanics include wall climbing, using springs to reach higher areas, and piloting hovercrafts in certain sections. The pacing is brisk, and the difficulty can spike unexpectedly, demanding quick reflexes and careful observation. Playing it feels like a mix of frustration and reward, where each completed stage brings a quiet sense of accomplishment.

Each game uses different controls, most DOS games use the keyboard arrows. Some will use the mouse , "Alt" ,"Enter" and "Space bar".
