Mugirl has now undergone a complete overhaul with substantial content updates, featuring various dairy products, a riding system (yes, you can now ride Mugirl), built-in facial animation, and various performance improvements.

Due to being a complete rebuild, this update is incompatible with saves from older versions and various expansions made for the older version. We will release an auto-upgrade patch soon; if you need urgent access, you can subscribe to the legacy version of Mugirl (uploading shortly).

Adds the Mugirl race - they're really cute! (◕‿◕✿)



Mugirls are a slave race designed through genetic engineering by a space conglomerate for space colonisation purposes. They combine human appearance with the robust physique of Muffalos, enabling them to adapt to high-intensity labour in various colonial environments.
Mugirls possess exceptional health and strength, with armour and damage reduction coefficients far exceeding those of ordinary races, making them excellent farmers and craftsmen skilled in basic tasks like planting, construction, and production;
However, they perform sluggishly in intellectual labour, particularly struggling with medical and scientific research. They are both reliable labour for the colony and, in a sense, objects of pity as products of genetic engineering.


Racial Characteristics



Diet


Their diet is largely similar to vanilla colonists, with the advantage of being able to eat grass~ Well, overall they aren't very picky eaters! A minor drawback is that consuming hay and nutrient paste slightly reduces their mood, as during their corporate days, this might have been all they got to eat (╥﹏╥).

Work


Incapable of Intellectual and Incapable of Medical tasks. Mugirls were originally designed to handle the colony's basic work, so don't expect much else~(´-ω-`). However, they seem somewhat competent in Artistic and Social tasks. They receive significant bonuses to basic work like Mining, Planting, and Building, making them qualified workhorses! (゚∀゚)

Combat


Incredibly tanky! They start with 100% innate armour, with Heat Armour specifically reaching 140%- born for blocking doors and soaking up traps! They also possess 35% overall damage reduction and a 130% melee damage bonus (like a cute female Ogryn (≧∀≦)ゞ)! Their weakness is a dislike for single-shot weapons, whose use lowers their mood, because who can resist the joy of automatic fire? ξ( ✿>◡❛).

Products


Mugirls can both produce milk and grow hair like Snow Cows, meaning they can generate significant colony profit even when idle! (*´∀`)~♥! Furthermore, using Mugirl milk in cooking provides a substantial healing boost- drinking milk is good for your health, after all! (*‘ v`*).

Adaptability


Mugirls are highly adaptable! Unless you're doing a naked ice sheet or space start, clothing is largely superfluous for them (Mugirl: Can we eat clothes? (*゚∀゚*)?


Apparel



Slave Restraints


Mugirls have a series of slave restraints used to limit their abilities; after all, with stats this high, escapes during transport would be a significant loss for the megacorporation (・ω・). Most Mugirls acquired by the player will typically be fitted with several restraints. These often impair certain basic capacities like Sight, Eating, Manipulation, and Moving. Players need to craft corresponding keys at the Smithy or Tailor Bench to release the Mugirls (which might be a form of "training play", I suppose~(つд⊂)).

Other Apparel


As mentioned, Mugirls are inherently a designed slave race, so they have limited basic clothing options. The existing pieces somewhat incorporate... erotic elements ⁄(⁄ ⁄•⁄ω⁄•⁄ ⁄)⁄? , likely due to the dubious tastes of the megacorporation's developers~

Armoured Apparel


For the reasons stated above, armoured clothing options are currently limited, but more will be added in the future! (Here's hoping for Best Ongoing Update! (っ●ω●)っ)


Other Features



Acquisition

Current methods for obtaining Mugirls are limited, primarily to purchasing from slave traders or friendly factions, crashed slave transport pods, or encountering wandering enslaved wild Mugirls. As compensation, however, a slave transport pod crash event is guaranteed to occur at game start, and rescuing them will make them join your faction! (゚∀゚)

Tether System

Non-mental-break Mugirls can be tethered like animals (right-click the Mugirl), and can also be tied to Wall Tethers or Caravan Hitching Spots (right-click the structure after tethering). Please enjoy! ⁄(⁄ ⁄•⁄ω⁄•⁄ ⁄)⁄

Affection System

When not busy, Mugirls will show affection to other colonists like animals do, giving everyone a mood boost (*゚∀゚*).

About Bugs


As this is my first race mod, it goes without saying that it's probably full of bugs~ As the mod's programmer, I (三项全能柊舞缇娜!) sincerely apologise to all the respected elders and fellow players_(┐「﹃゚。)_ .
