Changelog

Version: 0.2.26
Date: 2026-06-10
  - Replace Automated countermeasures 2 benzene flamethrower with an acidthrower turret (nullius-acid-turret) fed by sulfuric acid.
  - Acidthrower leaves slowing acid puddles and applies acid stickers like biter splashes; stream uses acid-projectile graphics tinted to match the puddles.
  - Automated countermeasures 2 now also requires Sulfur processing 1 (nullius-sulfur-processing-1).
  - Add mod thumbnail; update README for first release and fix Planet Castra mod portal link.
Version: 0.2.25
Date: 2026-06-10
  Initial release. Hostile robotic outposts on Nauvis for Nullius, adapted from Castra Prime (GPL-3.0).

  Enemy bases:
  - Surface monitoring nodes (ren-data-collector) spawn in walled compounds with laser and flamethrower turrets, power infrastructure, land mines, and mobile units.
  - Bases do not generate within 600 tiles of map origin.
  - Destroyed monitoring nodes erupt with a nuclear-reactor-scale explosion and leave a large scorch mark.
  - Perimeter walls use a wider offset and a centered vehicle gate on each face.

  Pollution and detection:
  - Re-enables Nullius pollution on Nauvis using the ren-data pollutant ("technological signature").
  - Factory machines emit ren-data only when their recipes recursively require electronics; plain power draw does not count.
  - Enemy entities never emit pollution or ren-data.
  - Mobile units stay near their outpost until ren-data pollution triggers an attack.

  Hostile forces (unlock with Nauvis evolution):
  - Scout android: engineer appearance, light-armor stats, melee attacks (0%).
  - Raider buggy: vanilla car, bullet attacks (10%).
  - Assault tank: vanilla tank cannon shells with turret animation (35%).
  - Harrier kamikaze: fast Defender-style suicide unit with explosive blast (50%).
  - Walker spidertron: vanilla spider legs and rocket attacks (65%).

  Combat scaling and balance:
  - Hostile attack damage scales with Nauvis evolution from 1× at zero to 4× at full evolution (+300%).
  - Monitoring nodes heal slowly; mobile units do not regenerate health.
  - Nullius magazines, missiles, and demolition gear realigned to vanilla combat values.
  - Five-tier Projectile improvements research chain for bullet damage and firing speed.
  - Startup setting ren-enable-auto-targeting (default on): Nullius guns and missiles acquire hostile units instead of ground-only demolition behavior.

  Player countermeasures (Nullius tech integration):
  - Personal countermeasures: grenades, compact firearm, improvised magazine recipe.
  - Automated countermeasures: electric gun turret and benzene flamethrower turret.
  - Anti-incursion systems: rifle, laser turret, and advanced magazine unlock.
  - Stone wall (half HP of reinforced walls) unlocked from Nullius masonry.

  Other:
  - Startup setting ren-enable-robotic-enemies to disable base generation.
  - English locale for all hostile entities and countermeasure items.
  - Fusion-reactor graphics bundled in-mod (no castra-prime-assets dependency).
