Our take on Project Silverfish

The open-ended design gives up guided progression: solving missions and handling threats depends on interpreting clues, selecting equipment, and accepting responsibility for decisions.

What is Project Silverfish?

Project Silverfish is an action-adventure FPS set in a hostile exclusion zone containing cold-war-era dungeons, anomalies, creatures, factions, and hidden artifacts.

Players investigate mysteries by following leads, finding clues, completing contracts, and uncovering secrets about humanity’s origins and extinction. Combat combines firearms with tools, equipment, artifacts, and crafted exotic weapons. Six pre-made classes are available, or players can customize an Inheritor with varied perk rolls and game rules. The world supports different approaches to threats rather than scripted solutions. Artifacts can provide passive buffs, produce special effects when charged with Eather, or be incorporated into firearms. Factions compete for power in the Zone, with players choosing whether to work with or join them.
