Pragmata Guide – All 5 Storage Expanders and 6 Cartridge Holders Locations

In Pragmata, both Storage Expanders and Cartridge Holders start with fairly low capacities before eventually being upgradeable with collectibles. These upgrades are scattered across multiple sectors and blocks, with a few unlockable via the various Cabin’s Stamp Club boards.

This guide lists every Storage Expander and Cartridge Holder location in the game — including those that require specific tools or doubling back to earlier areas.

📦 Quick Overview: There are 5 Storage Expanders and 6 Cartridge Holders in total. Several Storage Expanders require special tools (Lim Eraser, Cleanse) or Red Zone completion to access. Cartridge Holders are found in orange mechanisms — 2 in the wild and 4 from Stamp Club rewards.

💡 Collection Tips – What to Prioritise:

✅ Storage Expanders increase your carrying capacity — prioritise them early to avoid constant inventory management.
✅ Lim Eraser and Cleanse are essential tools for accessing certain Expanders — acquire them as soon as they become available.
✅ Red Zone completions unlock several Expanders — tackle these when you reach each sector.
✅ Cartridge Holders are found in orange mechanisms — two in the wild, four from Stamp Club rewards.
✅ Stamp Club rewards require Bingo completions — focus on these boards to unlock the remaining Cartridge Holders.
