RobCo Certified by Talkie Toaster

RobCo Certified adds a new three-rank perk with the same name. With the perk, if you have a spare Fission Battery and some scrap metal you'll be given the option to repair any robot you destroy, turning them into a loyal ally who'll follow you anywhere. Each rank allows you to repair bigger and better robots to command. RobCo Certification is designed to allow non-combat sciency characters to be viable, letting them unleash a horde of robot minions against those who would threaten them. Version 2.0 lets you upgrade your robots, improving their firepower, and gives you vastly more control over their abilities and skills. It also adds Companion Share & Recruit compatibility, so friendly repairmen can fix up damaged bots. Plus, Zeta addons! Now you can command alien robots, and teleport them down from the Mothership if you run out back in the Capital Wasteland. Get it here.

The SCC master file allows you to easily recruit any NPC you can open dialogue with. Recruited companions will follow, sneak and fight alongside you. Sharing and Caring Companions also allows you to trade with your friends and give them simple orders like 'wait' and 'dismiss'.
