SAND 40mm vs 80mm Cannon Guide
Pick the right Trampler cannon in SAND: 40mm vs 80mm, shells, manual loading, overheating, target priority, smoke checks, and boarding follow-up.
Updated:
Quick Answer
For most early SAND Raiders runs, I start with the 40mm Autocannon. It is easier to correct mistakes with, it uses 40mm shells, and its overheat window gives me time to steer or repair. I bring the 80mm Naval Cannon when I can control distance, manually load it before the fight, and use it for heavy pressure or finishing shots.
Cannon choice in SAND: Raiders of Sophie is not just a damage question.
The wrong cannon can make my Trampler look strong in the garage and useless in a real fight. If I bring the wrong shells, forget to load the 80mm, install a cannon but leave it empty, or shoot random structure instead of legs, I can lose before I understand what went wrong.
This page only covers cannon decisions. For full Trampler layout, extraction, and solo route planning, use the related guides at the bottom.
40mm vs 80mm: quick answer
| Cannon | Best use | Biggest risk | My early recommendation |
|---|---|---|---|
| 40mm Autocannon | General Trampler fights, leg pressure, beginner PvP | Can overheat or jam during long fire | Best first cannon |
| 80mm Naval Cannon | Long-range pressure, heavy hits, finishing damaged Tramplers | Slow fire rate and empty-gun mistakes | Strong after I understand spacing |
| Shotgun-style cannon | Close-range burst and brawling | Needs close Trampler positioning | Not my default beginner pick |
If I am still learning, I pick the cannon that lets me recover from mistakes. That is the 40mm.
If I already know how to keep distance, line up shots, and load before the fight, the 80mm becomes much more attractive.
Install the cannon before you drive
A surprising number of bad fights start before the Trampler even moves.
The cannon mounts are the fixed cannon positions on the outside edges of the Trampler. They look like empty gun placements or turret seats on the deck. A cannon kit sitting in storage does nothing until I install it on one of those mounts.
The basic install flow is:
- Pick up the cannon kit.
- Walk to an outside cannon mount on the Trampler.
- Face the mount until the install prompt appears.
- Press F to install the cannon.
- Load it before leaving.
- Check the gun itself before driving into danger.
This also matters after a fight. If a cannon is destroyed or swapped, I do not assume the replacement is ready. I install, load, then check.
Pre-load guns and avoid empty 80mm starts
One of the best early tricks is that guns and cannons can be treated like crates before they are unpacked.
If I press Tab on a packed weapon or cannon kit, I can load compatible ammo before I place it. That means I can keep a backup gun ready with ammo inside instead of scrambling during a fight.
This is especially important for the 80mm.
The 80mm can feel broken if I forget one simple step: it still needs to be manually loaded with 80mm shells. An installed 80mm that is empty will not save me when the enemy Trampler is already in range.
My 80mm check is:
| Check | Why I check it |
|---|---|
| 80mm cannon installed | A kit in cargo does not shoot |
| 80mm shells loaded | Wrong or missing shells lose the opening |
| Enough shells for the fight | A few shots disappear fast |
| Target is not too close | Slow shots are worse in panic range |
| Backup pressure exists | I do not want one slow cannon to be my only answer |
This is the main reason I do not recommend 80mm as the default beginner answer. It is strong, but it asks for cleaner setup.
Why I start with 40mm
The Rusty 40mm Autocannon Kit uses 40mm shells. Its description says it can work against ground targets, but the old barrel design can overheat and jam if it fires consecutively for too long.
That weakness teaches good fighting rhythm.
I fire in bursts, watch the enemy legs, adjust the wheel, repair if needed, and fire again. I am not just holding the trigger until the fight ends.
| 40mm strength | Why it helps early |
|---|---|
| Flexible range | I do not need perfect close positioning |
| Repeat pressure | Good for legs and cannons |
| Forgiving rhythm | Overheat windows give me time to steer or repair |
| Easier beginner timing | Missed shots feel less punishing than 80mm misses |
| Strong close pressure | Still useful if the enemy pushes in |
The 40mm is not better forever. It is better when I am still learning how Trampler fights actually flow.
When I bring 80mm
I bring 80mm when I want distance, heavy impact, and a better finishing option.
The 80mm Naval Cannon covers great distance, but it is harder to operate because of its slower fire rate. Every missed shot hurts more. I like it when I can keep a clean angle and avoid close chaos.
I like 80mm when:
- the Trampler is small enough to control cleanly;
- I can keep range;
- the enemy is already damaged;
- I have enough 80mm shells;
- another cannon or player can cover pressure;
- I want to finish a disabled Trampler.
I do not like 80mm when:
- I am still learning steering;
- the fight starts too close;
- I forgot to load it manually;
- I do not have enough shells;
- I am solo and being boarded.
The 80mm is a pressure tool. It is not a panic button.
How many shells should I bring?
The exact number depends on how aggressive I plan to be, but I do want a baseline.
| Setup | Minimum I am comfortable with | Why |
|---|---|---|
| 40mm beginner run | 60–80 shells | Enough to learn and survive one real fight |
| 80mm light run | 20–30 shells | Enough for one serious fight if I do not waste shots |
| 80mm PvP-focused run | 30+ shells | Better if I expect multiple engagements |
| Mixed 40mm + 80mm crew run | 80+ 40mm and 30+ 80mm | Keeps both pressure and heavy shots available |
| Disposable test run | Less is fine | Only if I accept the run may end early |
These are not perfect rules. Early Access balance can shift, and bad aim burns ammo fast. But I would rather give myself a real number than leave with “some shells” and hope it is enough.
Field damage reference
This is a rough combat reference, not a fixed damage chart. Early Access balance can change, and armor, angle, repairs, component health, and hit location can all change the result.
| Target | 40mm expectation | 80mm expectation |
|---|---|---|
| Light NPC Trampler | Several controlled bursts, especially if I am walking shots into legs or guns | Roughly 4–5 clean hits as an early field reference |
| Damaged player Trampler | Good for finishing legs, cannons, and exposed parts | Strong finishing pressure if the target is already slowed |
| Moving player Trampler | Easier to correct missed pressure | Misses are expensive because the fire rate is slower |
| Close target | Strong if I manage overheat | Risky if they close faster than I reload |
| Long-range target | Usable, but less punishing | Better if I can land clean shots |
My takeaway is simple: I use cannon fire to create control first. Break movement, remove guns, force repairs, then decide whether to finish, board, or leave.
Pre-fight scouting: smoke, fire, and visibility
The cannon fight often starts before anyone fires.
Before I commit, I scan for movement, smoke, and burning parts. Engine smoke, damage smoke, and fire can reveal a Trampler route or a recent fight before I have a clean shot.
| Signal | What I assume |
|---|---|
| Engine smoke moving across dunes | A Trampler route or player movement |
| Black smoke from damage | A fight may have just happened |
| Burning structure | Possible downed Trampler or loot opportunity |
| Cannon flashes | Enemy already has angle |
| No smoke but loud movement | Stay alert; they may be behind a dune or rock |
This does not decide 40mm vs 80mm by itself. It decides whether I should take the fight at all. If I see smoke near extraction, a large POI, or my route home, I slow down and choose the angle before the cannon choice matters.
Trampler size changes cannon value
Cannon choice depends on the Trampler carrying it.
A small Trampler is easier to reposition, presents a smaller target, and works better with hit-and-run pressure. That makes 80mm more appealing if I can keep distance and avoid boarding.
A larger Trampler can support more roles and more guns, but it is easier to see and easier to hit. For a larger build, I care less about one perfect cannon and more about coverage, shell count, repair access, and crew roles.
| Trampler type | Cannon style I prefer | Why |
|---|---|---|
| Small solo Trampler | 40mm first, 80mm after spacing improves | Mobility matters more than raw damage |
| Small PvP Trampler | 80mm can work if I keep range | Heavy hits are better when I control distance |
| Medium crew Trampler | 40mm + 80mm mix | One cannon pressures, one punishes |
| Large crew Trampler | Mixed coverage | Needs angle control, repair roles, and ammo planning |
| Close brawler | Shotgun-style options | Only if the layout supports close fights |
The wrong lesson is “80mm is better because it hits harder.” The better lesson is “80mm is better when my Trampler can use it safely.”
Target priority: legs first, cannons second
My target priority does not change much between 40mm and 80mm:
- Legs
- Cannons
- Exposed players
- Captain quarters if boarding is realistic
- Loot after the fight is controlled
Legs matter because they slow or stop the enemy. Cannons matter because they remove pressure. Once both are damaged, the fight becomes much easier to finish or disengage from.
This is why the 40mm is so useful early: repeated pressure helps me walk shots into legs and cannons. The 80mm can do it too, but missed timing hurts more.
Boarding follow-up: break captain quarters for the real payoff
Boarding is not just “jump on their Trampler and cause trouble.”
The real payoff is captain quarters. If I can break into the captain quarters and hold the takeover point, I can steal control of the enemy Trampler. That can cut off their respawn control, lock them out of their own doors, and turn their machine into my exit or loot haul.
But I do not board first.
My boarding sequence is:
- slow the Trampler by damaging legs;
- reduce cannon pressure;
- kill or delay a defender if possible;
- use explosives or angle pressure to open the captain quarters route;
- take over only when the enemy cannot easily punish me.
A good cannon does not just kill. It creates the boarding window.
Solo cannon choice
Solo players need control more than raw damage.
For the first solo runs, I still choose 40mm because it lets me make mistakes. I can pressure legs, pause during overheat, and use the window to steer or repair.
I use 80mm solo when I have a small Trampler, a clean distance plan, and enough shells. If I get pulled into close boarding chaos, the 80mm feels much worse.
For the solo route itself, use:
Crew cannon choice
A crew can use heavier setups earlier because the jobs are split.
For a three-player crew, I am more willing to mix 40mm and 80mm coverage. The 40mm keeps steady pressure on legs and cannons, while the 80mm punishes slow targets, exposed angles, or damaged Tramplers.
| Crew size | Cannon plan |
|---|---|
| 2 players | Keep it simple; 40mm is safer |
| 3 players | 40mm + 80mm becomes realistic |
| 4–6 players | Mixed coverage, dedicated driver, gunner, repair, boarding watch |
| New crew | Fewer cannon types, more ammo clarity |
| PvP crew | Stack pressure only when roles are clear |
The strongest crew cannon setup is not always the one with the biggest guns. It is the one the crew can actually load, aim, protect, and repair around.
What about shotgun-style cannons?
Shotgun-style cannons are not bad. They are just not my default.
They need close range, and close range increases boarding risk. If my Trampler layout is not built for close fighting, a shotgun-style gun can drag me into the exact fight I am trying to avoid.
I would use one when:
- the Trampler is built for close brawling;
- the driver can hold angle;
- someone watches doors;
- the target is already slowed;
- I have a clean disengage route.
Until then, the 40mm teaches better habits.
My beginner cannon loadout
| Slot | My choice | Why |
|---|---|---|
| First cannon | 40mm | Most forgiving starter |
| Heavy option | 80mm if loaded and supplied | Better range and finishing |
| Shells | 60–80 40mm or 20–30+ 80mm | Gives a real fight instead of a token loadout |
| Personal weapon | Simple gun with matching ammo | Stops boarders and PvE |
| Utility | Time bombs only with a boarding plan | Useful after disabling the enemy |
I would rather bring one cannon with enough shells than three cannons nobody loaded correctly.
Common cannon mistakes
| Mistake | Why it hurts | Better habit |
|---|---|---|
| Installing a cannon but not loading it | The Trampler looks armed but cannot fight | Load before leaving |
| Forgetting the 80mm starts empty | The opening shot never happens | Manually check the 80mm |
| Bringing mismatched shells | Ammo takes space but cannot fire | Match shell type to cannon |
| Shooting random structure first | Wastes pressure | Hit legs, then cannons |
| Ignoring smoke and visibility | I get spotted or surprised | Scan before committing |
| Boarding too early | I abandon my own Trampler | Disable first, board second |
| Choosing by damage only | Bigger hit is not always better | Match cannon to Trampler size and role |
The best cannon is not always the biggest cannon. It is the cannon I can actually load, aim, support, and recover with.

FAQ
Should I use 40mm or 80mm first in SAND Raiders? +
I would start with 40mm. It is more forgiving, uses 40mm shells, works at usable range, and gives me time to steer or repair during overheating windows.
Why does my 80mm not fire in SAND Raiders? +
The 80mm may be empty or loaded with the wrong shells. I manually check the cannon before combat because an installed 80mm still needs 80mm shells loaded.
Can I load cannons before unpacking them? +
Yes. I can press Tab on a packed gun or cannon kit and load compatible ammo before unpacking or installing it. This is especially useful for backup guns and 80mm setups.
How do I install a cannon in SAND Raiders? +
Pick up the cannon kit, walk to an outside cannon mount on the Trampler, face the mount, and press the install prompt, usually F. Then load the cannon before leaving.
How many shots does 80mm take to kill an NPC Trampler? +
As an early field reference, expect roughly 4–5 clean 80mm hits against a light NPC Trampler. Early Access values can change, so I treat this as a practical estimate, not a fixed breakpoint.
What should I shoot first in Trampler PvP? +
Shoot legs first, then cannons. Broken legs slow or stop the enemy, and broken cannons remove their pressure. After that, captain quarters pressure or boarding becomes safer.
