v1.5.1 — Fixes

Nuclear Devastator

  • Researching NUCLEAR DEVASTATOR now actually unlocks the building. It was also gated behind a lifetime casualty threshold, so completing the 6-cycle

research could leave you with nothing to build.

  • No longer unique — build one per available building slot. Cost raised to 5000 COMPUTE.

  • Losing the sector holding a Devastator no longer permanently blocks rebuilding it.

Research and buildings

  • Locked buildings now appear in the build menu greyed out with their unlock condition, instead of being hidden entirely.

  • Corrected skill descriptions that understated their real effects: TOTAL WAR is +20% combat and −20% unit cost (listed as 15%), SPECIAL FORCES are 10×

infantry power (listed as 5×), ORBITAL SUPREMACY takes strikes from 50% to 65% (listed as 30% to 50%). The effects themselves are unchanged — only the

text was wrong.

  • Added the missing RAPID DECONTAMINATION entry to the research encyclopedia.

Difficulty

  • HARD now increases how fast hostile sectors reinforce. This setting previously only affected rival spawn and advance timing.

  • Rival AI now escalates against players building a heavy economy alongside research. This reaction existed but could never trigger.

Interface and stats

  • FLEETS BUILT and INFANTRY BUILT on the lifetime statistics screen now count. They previously read 0 permanently.

  • Removed duplicate ADVANCE and TRANSFER UNITS buttons that appeared twice on controlled sectors.
