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.
With around 300 mods, the pack is well balanced and optimised, 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.
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.
For support or if you're looking for people to play with, check out our server here!
This is a code version of the modpack, which I recommend downloading instead since the mods will stay organised: 019a6ef6-873f-be77-7bbf-f3d733db78a1
Here is also our synced code (Note we sometimes push experimental changes to it though!): XpFxnNyOSwKo_XMZS-p0oA
Design / Balance
This modpack is a lil different to most others, in that we don't prioritise adding lots of content, nor do we care much for the Immersion/Fear/Comedy factor specifically. Instead, our primary focus is on solid gameplay, making sure everything is balanced well and feels good to play.
It heavily incentivises 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 prioritise 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 familiarise yourself with our many mechanics and how we have designed our various moons. Check out the wiki here!
Feature Footnotes
- 20 Hand-crafted, expertly balanced New Moons. Every one is unique and serves a function! See more here
- Over 25 cherry picked new Interiors, distributed and balanced well across the moons, creating variety 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
- 10 New Weathers, along with combined weathers, with a custom weather system and scrap values balanced properly to incentivise actually visiting weather whilst not being OP! See more here
- Over 40 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!
- Expensive upgrades in the ship without LGU, further encouraging playing well to afford them, yet being priced so that they're a fair sacrifice and most relegated to late-game runs!
- Sellable enemy bodies balanced well, making killing enemies more worth it without detracting from the collect-scrap focused gameplay!
- 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 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!
- An awesome WIP wiki detailing the stats, mechanics and strategies for stuff in the pack
Custom Mechanics
These are "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
- Weather in our pack progresses entirely through a Weather-To-Weather system, meaning weather is somewhat predictable and follows set rules (No Heatwave after Snowfall for example), which combined 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!
- 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!
- 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!
- In-game link to our Wiki/Discord!
Requirements / Setup
- By default, ViewExtension, HookGenPatcher, and MonoDetour may automatically be downloaded to the pack. Feel free to disable these! IKEA is optional.
- 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 though if they work with the pack!
