Acronia

Acronia delivers high-octane, side-scrolling action in a thrilling run ‘n’ gun experience inspired by the classics. Venture through mutant-infested labs, ravaged military bases, and perilous wildernesses as you uncover the sinister secrets lurking behind every corner.

As agents of Acronia, a private military contractor and security firm, you’ll soon find that your employer’s covert genetic experiments have spiraled out of control. After a catastrophic accident, the facility is overrun by monstrous mutants, and survival is the only goal. Armed with an arsenal of powerful weapons, your mission is simple: escape—and obliterate anything that stands in your way.

Featuring five distinct player characters, each with their own signature weapons and special abilities, Acronia will test your reflexes and endurance across three intense episodes of non-stop carnage. Prepare to dodge, dive, and destroy in a relentless battle for survival.

Old-School Roots, New School Power

Acronia began as a passion project for retro PCs, inspired by classics like Contra, Duke Nukem, and Bio Menace. Though early versions earned praise from the DOS and retrogaming communities, technical hurdles put the project on hold—until now.

Reimagined for modern systems while staying true to its ’90s roots, Acronia will feature VGA-style graphics, classic sound effects, and an authentic Adlib soundtrack powered by modern emulation. It may no longer run on DOS, but its heart beats in 256 colors, ready to bring retro action to a new era.

Note: trailer and screenshots showed here are from the original DOS version.

Development on the revived Acronia kicks off following the release of Enigma Heart. Stay tuned!
