Play Flux (requires Megacd) (program) Online

Flux is a Sega Mega Drive game that requires the Mega CD add on to run. It was released in 1994 by Sega, though it never received a formal retail release in many territories. This places it in the later part of the 16 bit era, a time when developers were experimenting with the expanded storage and audio capabilities of CD based consoles.

You control a small, agile ship navigating a series of abstract, geometric environments. Your main objective is to survive by destroying incoming geometric shapes and projectiles while collecting energy orbs to maintain your ship's power. The game's signature mechanics involve manipulating the playfield itself; you can rotate the entire screen to change the direction of gravity, and you must frequently warp between different planes of existence to avoid obstacles. The pacing is relentless, with the screen constantly filling with enemies and hazards, making it a difficult game to master. It feels like solving a frantic, spatial puzzle while under constant fire.
