Once Human Sintered Bricks: The Stone-Age Secret to a Raid-Proof Base
Fortify your Once Human base with sintered bricks by unlocking Forging Techniques and using an electric furnace.
Picture this: You've just spent four hours perfecting your dream home in Once Human. The living room has mood lighting, the garage is stuffed with loot, and you're feeling like a post-apocalyptic Martha Stewart. Then, out of nowhere, a pack of Deviations comes knocking—and by knocking, they mean tearing your wooden walls down like they're made of wet cardboard. It's a humbling experience, and it's exactly why smart players upgrade to Sintered Bricks faster than you can say "termite party."

Sintered Bricks aren't just fancy rocks glued together—they're the alpha and omega of base defense. Think of them as the steel-reinforced doors of the wasteland. Raider-proof? Close enough. Deviation-proof? Absolutely. And like any serious upgrade, getting them requires a bit of legwork and a whole lot of gravel. But fret not, because the guide below breaks it all down into easy-peasy steps, even if your crafting skills are currently at the "poke things with a stick" level.
The Memetic Maze: Unlocking the Good Stuff
First things first: you can't just decide to make Sintered Bricks on a whim, like slapping together a mud pie. You'll need to unlock the Forging Techniques memetic node, which lives under the Infrastructure tree. This is a Tier 3 node, meaning it's not for fresh-out-of-the-vault newbies. You'll have to fork over some Ciphers and Energy Links—but look at it this way: would you rather spend those resources now or rebuild your entire base after a 3 a.m. raid while sobbing into your keyboard? Exactly.

Once that node is glowing with your well-spent points, you're halfway to a fortress. The recipe itself is refreshingly simple: toss 10 Gravel and 3 Charcoal into any Furnace, and out pops a single Sintered Brick. No drama, no exotic materials that require you to befriend a mutant squirrel. Gravel you'll get from mining literally any mineral node—Tin, Iron, Copper, you name it. Charcoal? Just chop some trees, shove the logs into a Furnace, and voilà. It's the crafting equivalent of making toast.
Electrify Your Brick-Making Game
Here's where things get spicy. If you've already embraced the modern age and unlocked solar panels or bio-mass generators, you can kiss the Charcoal requirement goodbye. An Electric Furnace will churn out Sintered Bricks using only Gravel and a steady 5W of power. That's less electricity than a nightlight, so your base won't even notice. Just make sure your power grid isn't held together with chewing gum and hope, because an idle furnace is a sad furnace.
Now, the real bottleneck is Gravel. Swinging a pickaxe at every shiny rock gets old faster than a dad joke at a family reunion. The solution? An Electric Rock Drill. This beast of a tool not only gives you more resources per node but also deletes ore veins in the blink of an eye. Its crafting requirements might make you sweat, though: 35 Aluminum Ingots, 20 Special Parts, 20 Electronic Parts, 20 Metallic Fiber, and 1 Storage Battery. That's a shopping list that would make a hardware store manager weep.
Aluminum Ingots come from Electric Furnaces (see how everything connects?) and require Aluminum ore from level 30+ zones like Chalk Peak. Special Parts are best scavenged from industrial areas—refineries, workshops, garages—in regions like Chalk Peak or Red Sands. Basically, go where the rust is, and you'll find the goodies. The Storage Battery is its own mini-project, demanding 15 Steel Ingots, 20 Rubber, 20 Acid, and 10 Electronic Parts, all crafted at an Intermediate Supplies Workbench after unlocking the Electrical Kit node under Logistics. It's a crafting chain that might make your head spin, but hey, no one said living in a stone mansion was easy.
Pro Tips for Brick Barons
-
Bulk production is your friend. Gravel stacks high, so mine like there's no tomorrow. The Electric Rock Drill turns entire cliffsides into gravel soup in minutes.
-
Power management matters. When your Electric Furnace and drill are both hungry for watts, consider a dedicated generator for the workshop corner. Stagger crafting if you have to—nobody wants their lights dimming mid-craft.
-
Plan your upgrades. Start with the walls that face the most common attack angles. Deviations aren't known for their strategic brilliance, but they are persistent. A half-brick base is still half-vulnerable.
In the grand drama of Once Human, Sintered Bricks are the quiet heroes that keep your loot safe while you're offline dreaming of electric drills. So gear up, mine that gravel, and show those Deviations that your home isn't just a house—it's a statement. A very, very solid statement.
