Version 26.12.2017. Remake of Stx3's Hardcorio:SC2. Hardcorio:SC2 turns Factorio into a hardcore survival game, by completely replacing the enemies, combat mechanics and added life support requirements.
In vanilla Factorio, aliens usually do not attack them because it makes trains and separate bases impossible or too hard to maintain. Is this intended for hardcorio to punish players who expand?
Modification didn't set these buildings as main target. This is question about distraction of enemies. Just check mod-settings and read properties. You can disable "The enemy attacks all buildings that the player has built" and enemies will ignore Rails and Power Poles like usual.
