Here is the primary documentation on the mod, ported over from the forums/archive it would normally be found in. It contains a summary of some features, and other stuff of note.

<THE PENGUIN PIRACY MOD>

-------------------------------------------------------------------------


INTRODUCTION

Of the races in the Starbound universe, none are as adorable and mischievous as the little penguin.. and, while it's great that there are two bosses featuring them, and penguin mercenaries we can hire on as crew members.. haven't you ever wished there was more to these flightless birds?.. Perhaps, maybe you have wished you could "play" as a penguin?... Maybe you wish there was more content affiliated with the race?

Well look no further!

The Penguin Piracy Mod does just that: It can make the penguin race playable in Starbound, and aims to add a ton of penguin affiliated content!

------------------------------------------------------------------------

THE PENGUIN CHARACTER'S STORY

You are a lone penguin agent. Your mission: To get your little flippers on the legendary matter manipulator, so your race can reverse engineer it for the benefit of penguin kind!

Your mission goes smoothly at first: You knock out a protectorate graduate (sending them flying out into space in an escape pod), and "fill in for them" for the graduation ceremony.

After taking a quick nap, you nearly miss the ceremony, and then...

...

After a tragic chain of events, you are forced to flee planet Earth. Your ship is damaged. You're stranded in the middle of no where. For now, your mission is going to have to wait... for not only will you have to survive, but you are about to get swept up into an even bigger mess...

MOD FEATURES

-Greatly expands upon the penguin race, allowing them to be playable (To play as a penguin, you must use a race extender.. either the only packed with the mod (PPM-RaceExtender. This lets you play as a normal penguin) or one with more slots if you would like the others playable. (A race extender that adds AT LEAST four additional slots is optimal.)), it changes them in the following ways:

1. gives them a wide range of color options (Both for their body color, belly color, and beak/feet color)
2. gives them personality poses
3. offers a ton of cosmetic accessories for the penguins
4. makes them glass cannons: They have extremely nerfed health. They are extremely fragile unarmed, and rely on their tactical penguin armor (Which provides heftier buffs to their energy and attack damage!). They perform best by fighting from afar with ranged weapons, or in the safe confines of tunnels.

they also have bounce physics (a shock induced bounce when they hit the ground at the end of a jump), and slide slightly when standing on uneven surfaces.

-In terms of content as a playable race, they have:

1. A recolored/tweaked Old floran ship AI as the SAIL
2. A revitalized orbis ship pet, which comes in a vivid range of colors
3. A custom ship, inspired by Dreadwing's UFO
4. Their own race specific flag
5. A set of clothing that hides wearables
6. Custom hurtsounds and chattersounds. (penguinoid players also make a cute sound when they jump!)

-The mod expands penguin npcs. They have access to the expanded namegen, color options, and (in some circumstances) the penguin accessories. The Penguin Piracy mod adds penguin tenants and crewmembers!

Penguin mercenaries are improved, offering their services for five dubloons, in exchange for packing a larger array of potential weapons (From randomized guns, to flamethrower-like weapons!)


-Offers tons of penguin affiliated content:

1. Several crafting stations
2. A nice handful of decorative objects
3. Completely legal services that improve your penguin affiliated experience!
4. Juicy penguin lore and codexes (features malleable lore: It will be tweaked and improved in the event new information is revealed in the vanilla game about the penguins)

-And much MUCH more! If you want to know more, you'll have to experience it yourself! (If I revealed EVERYTHING here, it would ruin the surprise wouldn't it?)
