Evaluation

Extraneum launched its full v1.0 release on September 25, 2024, completing all 24 maps across 3 episodes that had been planned and developed since the game first appeared on Steam in June 2022. Developer David Jalbert explicitly described the 1.0 launch as a complete, content-finished product — the store page confirms 24 levels with 3 boss battles, and there were no promises of additional campaigns, expansions, or DLC made at launch or afterward. The post-launch activity has been limited to maintenance: a bug fix patch on September 29, 2024, a quality-of-life update adding camera smoothing on October 6, 2024, a bug fix patch on July 17, 2025, and Steam Deck verification on January 16, 2026. None of these updates introduced new content or hinted at future expansions. There are no unreleased DLC listings on the store, no season pass, and no developer statements suggesting more content is planned. The game was developed as a self-contained old-school first-person shooter, shipped as a complete package, and has received only routine upkeep since launch. Anyone waiting for all content is fully covered by the September 25, 2024 release.

About this game

THE STORY

Thanks to your high resilience and your even higher scores on the Universal Weapon Handling Assessment, you were lucky enough to get hired as a security guard for top secret Project EXTRANEÜM (pronounced ex-strain-yum). You had no idea what this project was all about, but you certainly didn't sign up for a total overrun of the facilities by alien looking monstrosities.

Looks like you're doing overtime today. Grab your trusty knife and your standard issue SMG and send these abominations back to hell where they belong.

THE GAME

EXTRANEÜM is a brutal old-school first person shooter with an emphasis on exploration and secret hunting. Shoot monsters and find upgrades as you progress through the laboratories of Project EXTRANEÜM in search for the truth... and a way to put an end to it all.
