I remember the first raid: sand in my teeth, alarms screaming, and the trampler taking blows it never should have survived. You can feel the panic—until you find the one upgrade that stops the bleeding. From that moment you stop praying and start choosing.
I’ve run dozens of sorties and studied the Tech Tree like a blueprint. You’ll get pulled into quick decisions—some cost you a run, others buy you breathing room. I’ll lay out the path I use so your trampler comes home more often than not.
On my first full repair cycle the trampler’s reactor was all I could stare at — it was either saved or we were stranded. The best Tech Tree upgrades to get first
You need priorities, not a wishlist. Treat the Tech Tree like a battle plan: small investments early that pay in survivability and loot. I focus on three threads—engine survival, crew survivability, and cargo capacity—and I build outward from there.
| Upgrade | Reason |
|---|---|
| Engine Upgrades | The trampler is your home in the sand, and keeping it sheltered is essential. Any upgrades for your engine (aka the Reactor) will increase its health, and keep it intact for a longer time during a battle. |
| Improved Reactor | Similar to the previous upgrade, a better reactor is necessary as you build up your trampler. |
| Crew Room | When you start with your first trampler, there won’t be much importance of a crew. However, having crew members will help you survive battles (since you can’t manage every nook and corner by yourself). Once you unlock this upgrade, you can add Crew Rooms to your trampler. |
| Battering Ram | Once you have built up your trampler and added the offenses, it’s time for defense. The Battering Ram is the best defensive upgrade in my books. It saved my trampler at on at least two different occasions. |
| Shovel | In SAND, more resources is key for quicker progression. The Shovel allows you to find items that are usually buried in the sand. Since this is a Tier 2 upgrade, it doesn’t take long to unlock. |
| Cannons | Cannons are the ultimate offensive arsenal for your trampler. They’re big, strong, and does plenty of damage. However, you’ll need to invest many resources to first unlock, and then build them. These should not be your early game unlocks, but don’t forget them. |
| Wooden Decks and Cargo Deck | These are simple unlocks that allow you to carry and keep more items on your trampler. In simple words, you’ll be able to extract with more loot from your runs. |
| Chassis Upgrades | There are multiple Chassis upgrades available from Godlewski’s Expedition. Upgrading the chassis allows you to install more upgrades, compartments, and more. |
| Workshop | Having guns and ammo is necessary if you want to remain alive. However, you can’t always get them from loot. Having a Workshop enabled on your trampler allows you to craft ammunitions from raw materials. |
Use the Workshop early enough to convert scavenged materials into steady gun and ammo supply. The ability to craft means fewer desperate scavenges, and more controlled progression through tiered fights.
What should I upgrade first in SAND: Raiders of Sophie?
Start with engine defenses and the Reactor. The trampler is a fortress when its heart is healthy—damage to the Reactor is a run-ender. After shoring that up, add basic cargo space so each sortie returns more than it risks.
How do Tech Tree upgrades affect trampler performance?
Upgrades shift the gameplay from survival gambling to calculated raids. Chassis options let you bolt more modules; Crew Room changes how much damage you can absorb without losing function; Workshop flips loot into reliable munitions. Each choice tilts the risk-reward math in your favor.
Where can I get the resources for upgrades?
Grinding sand caches is obvious, but scavenging specific zones and completing bonus objectives pays better. I cross-reference paths on Steam guides and skim r/SAND threads for spawn tips—PCGamingWiki has useful drop tables as well. Spend time on routes that have stacks of parts, not just scrap.
My short priority list, in order: Engine/Reactor health, Crew Room, Cargo Decks/Wooden Decks, Shovel, Battering Ram, Chassis expansion, Workshop, then heavy weapons like Cannons. This keeps your trampler breathing, carrying, and repairing between fights.
Small note: some upgrades cost serious resources—plan those purchases like a trader plotting a market move. Early runs fund defensive upgrades; later runs can afford cannons and chassis overhauls.
Watch the Tech Tree vendors: Godlewski’s Expedition is where you’ll find chassis paths that matter later in the campaign, and other vendors sometimes offer niche parts. Check vendor inventories after every run; prices shift and opportunities appear if you’re patient.
One final thought: pick upgrades that fix the weakest link on your trampler, not the flashiest piece you want. Will you accept slow gains now for safer runs later, or chase big guns that’ll cost you a dozen sorties to afford?
