Testudination
This modpack has been put together after thousands of hours of combined playtesting from myself, my group of friends, and some other friends in the community. A slimmed down version of this same modpack was used for the Bingo event in the LC Modding Discord Server, featuring many notable modders from the community.
Now sitting past 300 mods, the pack is well balanced and optimized, with every single interior/enemy/trap/scrap spawn very painfully carefully balanced for every moon, with lots of testing to get the feel right for it.
Despite the high mod count, lots of time and effort has been put in to ensure it is performant and that every mod included actually adds something of value. Additionally, all clientside stuff has it's own section so you can disable it easily.
Overall, this has created an experience that greatly expands on vanilla and adds much more variety, without things getting too over the top and maintaining good balance.

⚠️ This is a code version of the modpack, which I recommend downloading instead of directly from Thunderstore for organization and to prevent some issues: 019e55ce-63af-96d4-e3d3-c66e33247a66 ⚠️
⚠️We strongly recommend you use Gale mod manager over Thunderstore/R2modman. When importing, make sure it is to a new profile, and hit the advanced options dropdown and tick "Import All Files"⚠️
Here is also our synced code (Note we sometimes push experimental changes to it though!): OIRINM
Design / Balance
This modpack is a lil different to most others, in that we don't prioritize adding lots of content, nor do we care much for the Lore/Immersion/Fear/Comedy factor specifically. Instead, our primary focus is on solid gameplay, making sure everything is balanced well and feels good to play with repeated playthroughs.
It heavily incentivizes and rewards you for learning about the many new mechanics and systems, with them being worth taking advantage of due to the risk-reward we tie to these kinds of things. From there, comedy and fear then arise from pursuing later game runs with everything we have put in.
This has created a far more replayable experience than most content-heavy modpacks, which prioritize the short-term novelty of encountering things for the first time and having 10 bajillion unbalanced moons, rather than making repeated exposure to said things actually enjoyable, engaging and worth it.
Despite this, variety is still very much present, keeping new players on their toes and engaged until they're comfortable enough to try out modded higher quota runs with the pack.
Casual play still works with the pack, though again our focus is more on making it fun once you "get into it". And of course, we still have plenty of silly things put in carefully!
Our wiki is currently under construction and being updated gradually, but you may find it useful to familiarize yourself with our many mechanics and how we have designed our various moons. Check out the wiki here!
Feature Footnotes
- 22 Hand-crafted, expertly balanced New Moons. Every one is unique and serves a function! See more here
- Over 30 cherry picked new Interiors, distributed and balanced well across the moons, creating variety with each run but allowing you to prioritise moons with interiors you like more! There is a fitting "home" moon for almost every interior! See more here
- 16 New Weathers, along with combined weathers, with a custom weather system and scrap values balanced properly to incentivize actually visiting weather whilst not being OP! See more here
- Over 30 new creatures and 14 new traps, with the enemy spawns expertly balanced so its still mostly vanilla enemies where possible with just a lot more variety between moons, and with the traps never getting too out of control (outside of Embrion)!
- Existing enemies and mechanics revamped and improved to be fair but still more challenging on average!
- Rebalanced vanilla gear and new modded gear, resulting in gameplay encouraging and rewarding using equipment and making it less painful to do so!
- Well-priced upgrades in the ship without LGU, further encouraging playing well to afford them, yet being priced so that they're a fair sacrifice and mostly relegated to late-game runs!
- Sellable enemy bodies balanced well, making killing enemies more worth it without detracting from the collect-scrap focused gameplay!
- Quotas scale much better, requiring you to visit latergame moons sooner. Later quotas expand to have more days to meet them
- Less downtime at the Company with instant selling and instant buying of equipment! Spend more time actually playing the game!!
- Lots of simple QoL mods and small tweaks to improve the experience but maintain solid difficulty!
- Lots of bug fixes and performance improvements!
- Fumos, Dice, a Nuke, and a few other unique little scraps!
- Touhou Suits and some little references, feel free to disable them if they're not your kind of thing!
- A few silly SFX here and there, but nothing too annoying or oppressive!
- For those of you that are awesome enough to wanna play my modpack, i've made sure not to include any mods like DiffozTweaks to prevent you customizing the pack and adding your own mods you might want to play with. Play it how YOU want to play it! <3
- An awesome WIP wiki detailing the stats, mechanics and strategies for stuff in the pack!
Custom Weather System
- Weather in our pack progresses entirely through a custom Weather-To-Weather system, meaning weather is somewhat predictable and follows set rules (No Heatwave after Snowfall for example). This, paired with deadlier weather offering proportionally better scrap value, means you can be really strategic about it! See here for more info
- Cloudy weather acts as an alternative Clear, decreasing scrap count but increasing scrap value a similar amount, making the day a focus on finding a few high value items and playing around the Apparatus!
- Dust Clouds is the opposite of Cloudy, increasing scrap count but decreasing the value, making the day more about collecting as many items as possible, with a higher chance of finding powerful items!
- Hallowed is reworked to cause more spooky enemies to spawn in, as well as Mansioney interiors on moons where they would otherwise not occur!
- Forsaken is reworked to also cause more spooky enemies to spawn in to an even greater extent than Hallowed, sometimes inside and sometimes outside!
- Injections have been implemented, so that weather affects enemy spawns. For example, insects will not spawn outside during Snowfall, Tornados or other extreme weather, and more Aquatic enemies spawn during Flooded! There is many examples of this, which can be found on the wiki!
- Stormy is soft-reworked so random lightning occurs more frequently on latergame moons
- Eclipsed is soft-reworked so that how many extra enemies spawn is consistent between tiers of moons, so latergame moons will all spawn the same amount of enemies at the start, rather than some moons arbitrarily having more than others.
- Weathers have been injected into more moons than in vanilla. For example, Rainy can appear on March/Rend in our modpack, and Flooded can appear on Bozoros!
Unique Weather Variants
- Light Fog (Swaps between Cloudy and Foggy throughout the day)
- Flash Flood (Swaps between Rainy and Flooded)
- Bloody Night (Event, reworked Blood Moon to only occur at the end of the day, where enemies revive on a short cooldown, along with more Masked + Indoors Dogs + Outside CountryRoadsCreatures. This is our unique solution to balancing Blood Moon so that it works in a modpack with SellBodies!)
- Risk of Rain (Goes from Cloudy > Rainy > Stormy)
- Risk of Rain 2 (Goes from Cloudy > Rainy > Hurricane)
- Mini Meteor Shower (Turns to Meteor Shower right at the end of the day)
- Military Occupation (Boosted spawn rates of Robotic Enemies and Weapons)
Custom Mechanics
These are other "mechanics" i have created myself purely from how i have configured everything in the pack, that stand out from if you just downloaded the mods individually on default settings
- Dynamic moon prices, where upon routing to a paid moon, moons much cheaper become free to route to, moons close in price can be routed to for a flat amount (like $50 or so), and more expensive moons can be routed to for a discount equal to the current moon cost! There's now more reason to keep credits and bring back bodies, as swapping moons is affordable but still balanced!
- Dynamic moon risk levels, where the weather increases the difficulty of the moon on the terminal to make it more accurate!
- Selling at the company is 85% outside of final day, giving players the OPTION to sell early for safety or to aquire gear/a paid moon, whilst the optimal strat still being to sell traditionally!
- Wooden Crates provide many more utilities than store items, often containing useful scraps!
- Gifts and SDM Paintings can spawn any random creature! Look out!
- Easter eggs only explode when thrown at a fixed chance, without the vanilla good/bad egg coordinate system!
- The Backrooms interior exists at a 1%< chance on all moons that have the facility/mansion interior present, so you never know when you will get it!
- Custom loading music that changes depending on the weather!
- Summoning Salt Speedrunning music for the cruiser!

Our Community
Looking for people to play with? Want to see how your crew fairs against ours? Want some tips or tech support? Need some assistance implementing something from our modpack in yours?
We have our own Discord and small community around the modpack, where we provide all of the above, and have our own internal leaderboard/record system, where we compete in a friendly manner against each other to see how far we can get, with categories split based on the version of the modpack being used as well as how many players are in the crew!
We also host special events where we cook up weird variations of the modpack for a limited time and have people set records for them too!
If any of that interests you, come check it out!
Requirements / Setup
- By default: LethalSettings, HookGenPatcher and MouseSensitivityIncreaser are included but supposed to be disabled unless you need them. Feel free to disable these!
- In Gale, the modpack should be sorted by Ascending + Custom in the top right. From there, mods are split into sections. Everything in the clientside section should be able to be disabled without causing issues.
- Avoid updating any mods. Mods not updated in the pack will not have configurations for the new content, and some mods break others when updated, hence why they may not be updated still.
- We use Gale mod manager within our group, i cannot guarantee the modpack will work properly on r2modman/Thunderstore, but it should!
- My specs are a 12th gen i3-12100F, RTX 3050, and 16GB ram. With that, i can host lobbies fairly stabily with the modpack with 6 or so people whilst recording/streaming. Anything below my specs i cannot guarantee the consistent performance of, though people within my group on lower end systems have reported it working fine when disabling some mods in the clientside section and ensuring LethalSponge is turned on.
- Load times can be hefty, its recommended to have 10GB or more free of space on the drive you have Lethal / your mod manager installed to give BepInEx Load Asset Bundles Faster room to work with!
- We don't use any lobby mods outside of LobbyControl + MoreCompany, and we usually invite each other directly through steam or using LethalRichPresence discord invites. Feel free to add your own lobby mods though if they work with the pack!
