Fork of Reactive Evolution Factor by Ralnoc. Removes the Space Age dependency, making it compatible with base Factorio 2.0 and Space Exploration. Destroying alien spawners and worm turrets reduces the evolution factor. Optionally, killing individual biters and spitters also reduces evolution.
Small changes concerning balance, gameplay, or graphics.
Version: 1.0.5
Date: 2026-09-30
Features:
- Added "Enable Minimum Evolution Factor" setting. When enabled, evolution will never be
reduced below the Minimum Evolution Factor value (default 0.0001). Off by default.
- Added support for Explosive Biters, Cold Biters, and Toxic Biters (biters and spitters),
using the same reduction values as the Armoured Biters tiers.
Balancing:
- Reduced spawner reduction values to 1/10th their previous amount.
Version: 1.0.3
Date: 2026-05-27
Features:
- Migrated to 2.1 experimental.
Version: 1.0.3
Date: 2026-05-27
Bugfixes:
- Restored default pollution_factor to 0.00000025 to exactly match the Space Exploration
default map preset. The 1.0.2 reduction to 0.00000020 avoided the SE warning but caused
a mismatch in actual evolution behaviour vs SE's intended settings.
Version: 1.0.2
Date: 2026-05-09
Bugfixes:
- Further reduced default pollution_factor from 0.00000025 to 0.00000020 to sit comfortably
below the Space Exploration warning threshold.
Version: 1.0.1
Date: 2026-05-09
Bugfixes:
- Changed default pollution_factor from 0.0000009 to 0.00000025 to match the Space Exploration
default map preset, preventing SE's "harder than expected settings" warning on startup.
Version: 1.0.0
