Update v0.3.1 Biological Threat Update: Biomass & The Swarm

Update v0.3.1: Organic Infestation and Vent Navigation


The derelicts are no longer just cold metal and failing circuits. Something organic is spreading. In this update, we’ve introduced the Biomass System and a new crawling threat that will change how you secure the decks.

🦠 Biomass Overgrowth

A new organic hazard has been detected on several ship classes.

  • Spreading Infestation: Biomass now grows and spreads through rooms, clinging to walls and floors.

  • Tactical Obstacle: While it might seem harmless at first, it marks the territory of new threats and can obscure loot or critical terminals.

🐜 The Swarm: New Insect Enemies

We’ve added a new type of biological threat—fast, erratic, and deadly in numbers.

  • Insectoid Crawlers: These new enemies move differently than the drones or bipeds you've faced before. They are harder to hit and can quickly overwhelm a lone drone.

  • Swarm Intelligence: Be careful when entering rooms covered in biomass—you never know how many are hiding in the growth.

🕳️ Ventilation Crawling

The ship's maintenance shafts are now a tactical option.

  • Vent Navigation: We’ve overhauled the ventilation grates. Smaller drones can now use vents to bypass locked doors or flank enemies.

  • Monster Flanking: Watch your back! Certain monsters can now use the same vents to surprise you from behind. Nowhere is truly safe anymore.

🔫 Defense Systems & Fixes

  • Tower Targeting Fix: Defense Towers have been re-calibrated. They will now correctly identify and fire upon biological monsters (including the new insects) instead of just mechanical threats.

  • Stability & Pathfinding: Various bugfixes for drone navigation and interaction logic with the new organic elements.

🛰️ Feedback Needed!

How do the new insects feel? Is the biomass too thick? Join our Discord and let us know what you think about this shift towards biological horror:
