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.
Different health, different inventory size, different running speed, unsure beyond that, did not look far. If you want large inventory go support, if you want fast speed go assult, if you want max health go heavy (also decent inventory, not as decent as support though), and soldier seems to be fairly balanced. Unsure beyond that.
