Rust Raid Guide 2026: Boom Costs, Tools & Defence

The classic new-raider mistake is dumping two C4 on a stone wall because it looks like the weak point — 4,400 sulfur gone, when the loot room was behind a sheet metal door two tiles over that would've cost one. That's the whole game right there. This rust raid guide is about not making that mistake, because raiding in Rust isn't about how much boom you own, it's about hitting the right wall with the cheapest thing that breaks it.

Raiding is how you take other people's stuff. Someone farmed for six hours, walled up their loot, and went to sleep or logged off. You show up with explosives, punch a hole, and empty their base. Simple to describe, expensive to do wrong. Get the costs in your head first and everything else follows.

How raiding actually works

Every base is a shell of walls and doors protecting a tool cupboard and a loot room. The tool cupboard (TC) is the thing that stops the owner rebuilding while authorised, and it's usually what you're hunting for alongside their boxes. You blow through the outer layer, you follow the path inward, and you either reach loot or run out of explosives first.

The two numbers that matter are the health of what you're hitting and the sulfur cost of the tool you hit it with. Sulfur is the raiding currency. Everything explosive is made from it, so every raid has a real price, and a good raider is basically an accountant who happens to own rockets. Before you throw a single charge, know what's cheaper: the door or the wall next to it. Nine times out of ten it's the door.

The explosives, and when to reach for each

You've got a handful of tools and they all trade cost against speed and noise. Here's how I think about them.

C4 (timed explosive charge) is the king. Two thousand two hundred sulfur a pop, sticks to anything, instant detonation, no aiming skill required. You slap it on and it goes. Expensive, but it's the most sulfur-efficient thing against high-health walls and doors, and it never misses.

Rockets need a rocket launcher and they cost 1400 sulfur each in raw terms. Faster to deploy than C4 in a firefight because you're firing from range, but you'll use more of them on thick walls, and they can be blocked by a lip of terrain or a wall foundation. Good for turrets and doors, wasteful on armored anything.

Satchel charges are the mid-tier and the solo's friend. 480 sulfur each, but they're unreliable. They dud. You'll throw four at a sheet metal door and one won't go off, so you re-arm it and lose time. Cheap sulfur, expensive patience.

Beancan grenades are 120 sulfur and even more of a gamble. They dud constantly and do chip damage. Their real job is popping tool cupboards and wooden doors, or stacking a bunch to soften a stone wall if you're desperate and broke.

Explosive 5.56 (eco raiding) is roughly 25 sulfur a round. You shred a soft target by unloading a rifle into it. Underrated for solos and duos who can't afford C4 but can farm a ton of gunpowder and metal. Slow, loud, and it eats your barrel, but the sulfur math is the best in the game on the right target.

Raid costs per structure (hard side)

This is the table I wish someone had tattooed on my arm when I started. All of it is the hard (outside) side. Sulfur in brackets is total for that method.

Want to plug in your own base or double-check a number mid-raid? The raid calculator and the full raid chart have every structure and combination, and there are per-structure breakdowns like the sheet metal door raid cost if you want to see the exact damage rolls.

Door, not wall: the math everyone gets backwards

Look at that table again. A sheet metal door is 250 HP and dies to a single C4 (2200 sulfur). A stone wall next to it is 500 HP and needs two C4 (4400 sulfur). Same base, double the price, and beginners hit the wall because it feels like the "main" way in.

Raid the door. Almost always. Doors are the cheapest entry point on most bases because owners upgrade walls to stone and metal but leave sheet metal doors, and a metal door is half the cost of the wall it sits in. The exception is when the door is armored (800 HP, 3 C4) and there's a wooden or unfinished wall nearby, or when the door leads into a dead airlock instead of the loot. That's the other half of raiding: reading where the loot actually is before you spend.

If you ever catch yourself about to rocket a stone wall when there's a sheet door in the same room, stop. You're lighting sulfur on fire. Check the stone wall cost next to the door cost and pick the smaller number.

Finding the cheapest path in

Good bases are onions. The outer wall is a decoy layer, and behind it is honeycomb (extra walls packed tight so you can't tell which one hides the loot). Your job is to find the shortest line from outside to the loot room without paying for a single wall you didn't need to break.

Walk the base first. Count the doors, look for the compound shape, find where the TC probably sits. Interior walls take about 50% more damage than exterior ones, so if you can get inside cheap through a door and then blow an inner wall from the soft side, your sulfur goes further. The soft (interior) side of any wall is weaker, which is why raiders fight to get one charge inside and then work outward-in.

The best path is often: one C4 on a sheet door, walk in, and one satchel or C4 on the inner loot-room wall from its soft side. Two charges, in the loot, done. Compare that to eight rockets grinding through the outside of a sheet metal wall and you see why pathing beats brute force every time.

Raid tools: launcher, GL, and what you carry

The rocket launcher is the standard boom-delivery tool. Slow reload, but you fire from cover and out of turret range if you angle it. You'll want it for turret-heavy bases since a single rocket kills a 1000 HP auto turret.

The grenade launcher (GL) with HE grenades is a support tool, not a main raider. It's good for clearing turrets, breaking wooden doors, and generally being annoying to defenders, but the sulfur-per-damage isn't there for serious walls.

For a real raid, most people carry C4 as the workhorse, a rocket launcher plus rockets for turrets and range, satchels as cheap filler, a hammer to check upgrade tiers, building plan and resources to wall behind you, meds, and a decent gun for the fight. Bring more boom than the calculator says. Duds, misreads, and honeycomb eat your margin, and nothing's worse than being one satchel short of the loot with the owner logging in.

Online vs offline raiding

Offline raiding is hitting a base when nobody's home. No one shooting back, no one repairing walls between your charges, you just methodically peel the base. It's the cleanest, cheapest way to raid because you're only paying to break structures, not to win a gunfight. A clean offline where you walk in, empty three loot rooms, and walk out with someone's whole wipe is one of the most satisfying feelings the game gives you. It's also why people rage-quit Rust.

Online raiding is hitting an occupied base, and it's a different animal. Now they're repairing the wall you're breaking, shooting you off the roof, and calling their group. You need to out-DPS their repairs, which means faster explosives (rockets and C4 over satchels) and usually more people. Online raiding is where zergs (big groups) dominate, because they can push bodies through the hole while others keep laying charges.

I'll be honest: most raiding on most servers is offline, and there's a running argument about whether that's cowardly or just smart. It's smart. You raid when the risk is lowest. The counter is building a base that survives offline, which brings us to defence.

Raid defence and counters

You can't make a base unraidable. You can make it expensive enough that nobody bothers, or slow enough that you wake up and fight back. That's the whole goal of defence: cost and time.

Honeycomb is the core of it. Extra layers of wall around your loot so a raider can't just blow one wall and be inside. Every honeycomb cell is another wall they pay for, and since they don't know which cell hides the TC, they either overpay or guess wrong. Good honeycomb turns a two-C4 raid into a ten-C4 raid, and most people won't spend that on a solo base. Read the base building guide for layouts that honeycomb efficiently without bankrupting you on upkeep.

Bunkers are hidden compartments you access through a mechanic (like a garage-door or foundation trick) that raiders can't easily open or find. Stash your best loot in a bunker and even a successful raid might miss it.

Auto turrets shred anyone who peeks without cover, and they force raiders to spend a rocket each (1400 sulfur) just to clear them before the real raid starts. Stack a few and you're adding real cost to every attempt.

Shotgun traps and flame turrets cover the inside of your airlocks and loot rooms, so even if they blow the door, they eat pellets stepping through. Cheap, mean, and great against the naked who rushed your open door.

None of these stop a committed group. What they do is make your base a worse deal than the base next door, and raiders, being accountants, go raid the cheaper one.

Eco raiding, and why solos should care

Eco raiding means using the cheapest sulfur-per-damage methods even though they're slow: explosive 5.56 and beancans mostly. A sheet metal door costs 63 explosive rounds at roughly 25 sulfur each, so about 1575 sulfur versus 2200 for a C4. You save real sulfur and you skip the C4 tech tree entirely, which matters early wipe when you can't craft C4 yet.

The catch is time and noise. Sixty-three rounds into a door takes multiple reloads, burns your gun's condition, and screams your location to the whole server. For an offline on a small base, that's fine. For anything online or contested, the slowness gets you killed. I eco raid as a solo in the first day of a wipe when nobody has C4 either, and I switch to C4 the second I can afford it. If you're new to the whole loop, the beginner's guide covers how to farm sulfur fast enough to raid at all.

The etiquette and reality of vanilla raiding

There isn't any etiquette. That's the honest answer. Vanilla Rust has no rules against offline raiding, door camping, or wiping someone's entire base while they sleep, and anyone who tells you raiding is "toxic" is usually someone who just got raided. You farmed the boom, you took the risk of exposing your base to bring it, and the loot is yours.

What's real is the social layer. Raid a big group's base and get greedy, and they'll come find your base and end your wipe out of spite. Raid a solo two tiles from your door and you've made a permanent enemy who knows exactly where you live. Pick targets that are worth the sulfur and won't come back to bite you, and always, always know your exit before you blow the entrance.

The best raiders aren't the ones with the most C4. They're the ones who spend the least to get the most, who read a base and know the door is cheaper than the wall before they arm a single charge. Get the costs in your bones, hit the soft points, and never rocket a stone wall when there's a metal door in the same room.
