Sophisticated ATM Tiers
If you have ever stared at a Netherite backpack and thought "this is great, but I want more," you are exactly the player this add-on was made for. Sophisticated ATM Tiers pushes Sophisticated Backpacks and Sophisticated Storage past their usual ceiling by bolting three brand-new endgame tiers onto the progression: Allthemodium, Vibranium and Unobtainium. The materials come straight from the Allthemodium mod, which means the whole thing feels like a natural continuation of the ATM modpack experience rather than a random bolt-on.
This is an add-on, and that word matters. On its own it does absolutely nothing. You need Sophisticated Backpacks, Sophisticated Storage, Sophisticated Core and Allthemodium installed for any of it to work. Once those are in place, though, the payoff is very real.
What Sophisticated ATM Tiers Actually Adds
The core idea is simple: three new tiers that sit above Netherite, each one bigger and more capable than the last. The progression runs Allthemodium, then Vibranium, then Unobtainium, and it applies to both your backpacks and your storage blocks.
- Allthemodium: 150 slots in a 10 by 15 grid
- Vibranium: 162 slots in a 9 by 18 grid
- Unobtainium: 180 slots in a 10 by 18 grid
Those are clean, full-row grids, so nothing looks awkward or half-empty. Even better, the base Netherite storage and backpack get the wider 15-column grid too, which means they finally stop scrolling. That alone is a quality-of-life win for anyone who has ever lost an item in a scrollbar.
Backpacks, Barrels, Chests and Shulkers
Every storage type gets the treatment. Barrels, chests, shulker boxes and limited barrels all support the new tiers, and all wood variants and dye colors show up properly in the Creative menu and in JEI. Stack upgrades continue the Sophisticated progression as well, with Allthemodium at 32, Vibranium at 64 and Unobtainium at 128, slotted neatly between the top Sophisticated stack upgrade and Omega.
Upgrading is refreshingly painless. Backpacks use smithing tier-ups with a Netherite template plus the tier ingot, and your contents and upgrades carry over. Storage blocks use crafting tier-ups, and there are also in-place tier upgrade items. Right-click a placed storage block and it bumps to the next tier without you having to empty it first, exactly like Sophisticated's own tier upgrades.
Supported Versions and Loader
Sophisticated ATM Tiers targets Minecraft 1.21.2 on NeoForge. It has been tested against Sophisticated Core 1.4.x, Sophisticated Storage 1.5.x, Sophisticated Backpacks 3.25.x and Allthemodium 4.0.x. Other minor versions of the Sophisticated mods may change the internals this add-on relies on, and those mismatches are blocked on purpose, so grab the matching add-on update whenever a new Sophisticated line drops.
A Quick Word on Compatibility
This add-on hooks into Sophisticated internals through Mixins. That is a technical way of saying it reaches into the mod's guts, and those guts can shift when Sophisticated Backpacks, Storage or Core update. If you crash right after updating the Sophisticated mods, check whether this add-on has a matching update before anything else, and report issues here rather than to P3pp3rF1y. Keeping the add-on on the Sophisticated version it was built for avoids surprises entirely.
Players who would rather skip the manual file shuffling often grab it through the foxygame.net launcher, where Sophisticated ATM Tiers sits in a curated add-on catalog and installs alongside its required dependencies in a single click, with version compatibility handled automatically.
How to Install Sophisticated ATM Tiers
Getting set up is straightforward if you already run a NeoForge profile.
- Confirm you have NeoForge for Minecraft 1.21.2 installed and working.
- Download Sophisticated Core, Sophisticated Backpacks, Sophisticated Storage and Allthemodium, and drop them into your mods folder.
- Download Sophisticated ATM Tiers and place the jar in the same mods folder.
- Add JEI if you want every wood and color variant listed as its own entry.
- Launch the game and check the mods list to confirm everything loaded without errors.
If the game refuses to start, the usual culprit is a version mismatch between the add-on and the Sophisticated mods. Match them up and you should be fine.
Final Thoughts
Sophisticated ATM Tiers for Minecraft fills a gap that many endgame players feel but rarely articulate: the storage ceiling arrives too early. By extending the tier ladder with Allthemodium, Vibranium and Unobtainium, this add-on keeps progression meaningful long after Netherite, and it does so without breaking the systems P3pp3rF1y built. The wider grids, painless in-place upgrades and full JEI support make it feel like official content rather than a patch. If you run an ATM-style pack and want your backpacks and storage to grow with you, this is an easy recommendation.
