addedUpdate v0.3.1: Organic Infestation and Vent NavigationThe 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.

added🦠 Biomass OvergrowthA new organic hazard has been detected on several ship classes.

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

added🐜 The Swarm: New Insect EnemiesWe’ve added a new type of biological threat—fast, erratic, and deadly in numbers.

added🐜 The Swarm: New Insect EnemiesInsectoid 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.

added🕳️ Ventilation CrawlingVent Navigation: We’ve overhauled the ventilation grates. Smaller drones can now use vents to bypass locked doors or flank enemies.

🦠 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 ObstacleWhile 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 CrawlersThese 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 FixDefense 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 & PathfindingVarious bugfixes for drone navigation and interaction logic with the new organic elements.
