The trampler groans under new weight as sand scrapes the hull; you freeze, menu pulsing with options you can’t afford yet. I’ve spent hours scrapping the desert for parts, and I still remember the sting of buying the wrong chassis. Stick with me—I’ll steer you past expensive mistakes and toward upgrades that matter.
I write this as someone who has chewed through every vendor list and tested builds on Steam, Reddit threads, and the official Discord. You’ll get clear cost signals, recipe notes, and the practical order I recommend so your trampler stops being a joke and starts being a threat.
On my workbench a pile of bolts tells a story — All Tech Tree technology upgrades in SAND: Raiders of Sophie and how to obtain them
Every tech branch is a small economy. Some parts are common; others are locked behind rare loot or community trades on Steam Workshop. Below I break the tree into the three vendors you’ll meet, list every upgrade, and show the exact in-game price plus a quick note on the hidden cost: recipe crafting.
How do I get Tech Tree upgrades in SAND?
Short answer: you buy the blueprints from the three creators using Crowns, then craft the recipe at a crafting station—recipes cost resources beyond the blueprint price. Think of the blueprint as the ticket and crafting as the fare.
What does a recipe cost to craft after purchase?
Blueprint prices are one thing; recipe production eats materials. I’ll flag the heavy hitters so you can budget Crowns (≈ EUR) and raw goods from Leviathans, Coral, and found caches traded on Discord or sold on Steam community markets.

Practical notes: I recommend you buy chassis first if you’re building capacity or mobility, and buy Landwehr weapons only when you can protect them with armor from the same vendor. If you’re short on rare materials, check Steam and community trades before spending 90–120 Crowns equivalents—those rare parts often show up on Discord swaps at better value.
For crafting order, I follow a simple sequence: secure your drive, add at least one defensive module, then expand weapons. The process is like stacking suitcases in a crowded car—balance matters more than size. When wiring engines and reactors, think of the trampler as a clock: every cog you add changes how the whole thing breathes, and a bad fit can stop it cold, so pace your upgrades and test after each major buy.
Want a curated build list tied to Steam Workshop loadouts or a Discord trade checklist to shave off wasted Crowns—do you think your trampler should be a mobile anvil or a swift raider?
