Complete Tech Tree Guide: Every Upgrade and How to Unlock Them in Sand
Tech Tree progression is the core growth system in Sand: Raiders of Sophie, letting you unlock new Trampler parts and related crafting options, plus shop purchases. The catch is that most Tech Tree nodes don’t just ask for Crowns (the game’s money)—they also require additional crafting materials. This guide compiles every Tech Tree upgrade mentioned here and the prerequisites needed to unlock them, so you can plan your next unlocks without getting stuck mid-grind.

How Sand: Raiders of Sophie’s Tech Tree works
In Sand: Raiders of Sophie, the Tech Tree is split into three distinct branches: Kaiser’s Friends, K.K. Landwehr, and Godlewski’s Expedition. Moving through the tree unlocks new Trampler components you can craft, alongside items you can buy in the shop. Early on, some nodes may be accessible using Crowns alone, but later unlocks demand extra crafting resources—particularly materials tied to Weird Corals—to reach higher-tier upgrades.
Below is the complete set of Tech Tree upgrades listed in the provided material, along with every requirement explicitly shown, so you can stockpile what you’ll need and keep your Tramplers progressing.
