Commander Keen: Atroxian Realm

Commander Keen: Atroxian Realm – Massive DOS-Style Fan Sequel

Commander Keen: Atroxian Realm is a fan-made, large-scale Commander Keen adventure built on the classic DOS platforming style of id Software’s original series. Designed as an unofficial continuation of Keen’s story, it delivers expansive levels, new enemies, original graphics, and fresh gameplay mechanics while preserving the charm of the early ’90s PC platformers.

Story and Setting

After his earlier adventures, Billy Blaze — the boy genius better known as Commander Keen — receives a distress signal from a distant star system. An ancient AI race known as the Atroxi has awakened, threatening worlds across the galaxy. Keen sets out to explore alien planets, infiltrate Atroxian facilities, and shut down their plans before it’s too late.

Gameplay

• Classic Keen Movement – Smooth running, pogo stick jumps, and precise platforming.
• Exploration-Focused Levels – Large, interconnected maps with secrets and optional areas.
• New Enemies and Hazards – Over 30 unique foes, each with distinct behaviors.
• Upgraded Weapons – Keen’s neural stunner returns with improvements, plus new tools for tackling challenges.

Visuals and Audio

Atroxian Realm uses an enhanced Keen Galaxy engine to deliver detailed backgrounds, smooth scrolling, and a richer color palette than the original Keen games. The soundtrack features new compositions inspired by AdLib/Sound Blaster FM synth music, keeping the retro DOS feel alive.
