Subnautica Pets SN

The Alterra Corporation may be known for their monopoly of the weapons trade during The Expansion, but what they desire more than profit is control. Control of the weapons markets, control of their devoted employees, control of the very environments in which they operate.

Ever on the lookout for opportunity, Alterra executives devised a secret mission: the scientific crew of the Aurora were to tame and weaponise the native creatures of 4546B. These innocent beasts were to be transformed into formidable weapons, ready to march into battle as foot soldiers of the highest bidder.

However, fate had different plans. The Aurora met a tragic demise, thwarting the realisation of this ambitious goal. In the explosive aftermath, strewn across the wreckage of the stricken vessel, cloning equipment lies broken, the mission unfulfilled.

Ever enterprising, you see not waste but untapped potential. While these creatures may be useless as weapons to you, they hold the promise of companionship and hope in troubled times.

Installation and Dependencies

IMPORTANT! This mod uses BepInEx and Nautilus. You must install the latest versions of these to use this mod. As the 2025 patch broke a lot of mods, you must use Nautilus version 1.0.0-pre.50 or later.

REALLY IMPORTANT! Because the mod spawns new collectable resources, you must start the mod in a new game. I'm really sorry, but this is a limitation of the Subnautica spawning system, where resources are spawned and persisted during gameplay.

User Guide

With this new Subnautica Pets mod, I've rebuilt from the ground up, introducing "lore-friendly" gameplay around the “Pets” concept. With this in mind, this mod is ideally played "as is", with discovery playing a part in getting the most out of the mod. As such, I recommend you play the mod in "Adventure" mode! When it comes to collecting resources, don't forget the Scanner Room and Scanner Room Chip - scanning for resources is your friend!

That said, if you're in the end game and just want to enjoy having some beasties running around your base, you can enable "Creative" mode in the mod options to unlock everything. All you need then is titanium, and you can explore all the mod has to offer. Switching modes requires a restart of the game, but can be done mid-save.

Note that "Custom Pets" don't require DNA, and are not a part of the "Adventure" lore-friendly experience.

Unlike previous versions, there are no other “mod options” or keyboard shortcuts. All mod functionality is built into the game.

Spoilers

This new version of the Pets mod has been created in a way to make the experience more "organic", with discovery and task/reward-focused gameplay, rather than "instant access" to pets. If you want to get straight to spawning Pets, you can find spoilers on how it all works here or simply enable "Creative" mode, save, quit, reload, and enjoy! You can spawn DNA via the console using the standard "item" command - just use these item names in your command:

• AlienRobotPetDna
• BloodCrawlerPetDna
• CaveCrawlerPetDna
• CrabSquidPetDna
• CatPetDna
