Evaluation

Project Silverfish has been in Steam Early Access since late June 2025 and is still on its 0.x Beta version line, with the store listing still available for purchase. The newest update, Beta 0.4.11, was posted on October 9, 2026, and added new weapons, dungeons, artifacts, passive effects, and secrets. It also brought in the changes from the 0.4.5 public test build released on June 13, 2026. In that June post, the developer said the 0.4.X update had been slower to arrive than planned because of personal circumstances, including a move. Substantial updates have also been posted on December 13, 2025, February 17, 2026, and June 13, 2026. The developer stated on December 13, 2025 that proper story endings will be added later in development, and on August 31, 2025 described end-game content as still a work in progress. Because the story endings and end-game content have been described as still to come, the game is not finished.

About this game

Project Silverfish is an immersive sim, FPS where you rely on your own wits and diverse sets of tools and weapons to survive!

Venture deep into a hostile and mysterious exclusion zone to hunt powerful artifacts, fight horrifying creatures and descend deeper into lost, cold-war era dungeons!

Solve complex mysteries, tracing the paths of other explorers, and digging up terrible secrets once lost to time. 

Work to uncover the dark secrets of your people's origins, and humanity's extinction...

Choose between 6 distinct pre-made classes or customize your own Inheritor of humanity's ruin!
With a variety of perk rolls and game rules, you can create a unique experience each time you play!

A massive immersive sim world where you choose how you engage with problems and threats. With a mix of tense gun-play, diverse sets of tools and equipment, and no scripted solutions or hand-holding: 

You are in-charge of your own decisions! 

You are responsible for your own mistakes...

Delve into dark, hidden dungeons.

Navigate treacherous Anomalies.

Face hideous monsters born of a cursed past.

In The Exclusion Zone, you're not always just a hired gun, you're also going to need to apply detective skills and deductive reasoning to find answers...

Complete Contracts and Missions by exploring the world, chasing leads and finding clues! Sometimes the truth can be stranger than any anomaly or mutant...

Among the many mysteries of the Zone, there are also powerful artifacts. 

They can grant passive buffs, or when charged with Eather, cast seemingly magical effects.

Some can even be crafted into exotic firearms, allowing you to exploit their secrets in combat!

Be careful, you're not the only one hunting out here...

Be prepared to discern friend from foe out in the field!

Several factions are vying for power out in the Zone. Some looking to control its secrets, others seeking to destroy the very source of its anomalies.

It's up to you to decide who you're willing to work with, or even join should they convince you...
