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.

This update overhauls the rival AI from the ground up—it arrives earlier, reads the board, counterattacks when you push into its territory, digs in when you leave it alone, and takes real losses when you break its assaults.
