How the weapon pick works
Crab Champions is a third-person roguelite shooter by Noisestorm, and the most important decision you make happens before the action even starts. At the run select screen you choose one weapon, one ability and one melee. The weapon is locked for the entire run — you cannot swap it mid-run no matter what drops. That single rule is the reason this guide exists: get comfortable with what each weapon does so you are not stuck with a tool that fights your playstyle for an hour.
The store currently lists 19 weapons, so there is plenty to grow into. What keeps the locked pick from feeling restrictive is the mod system: 89 weapon mods can reshape how your gun behaves, from projectile speed and spread to damage auras. So you are not really choosing a fixed weapon — you are choosing a foundation that you then build on as the run develops.
Because melee is a separate slot, melee weapons such as the Katana are picked independently and are not part of the gun decision below. The same goes for ability mods and melee mods, which are their own upgrade types. This guide focuses on the primary weapon — the one you will be firing most of the time.
The weapon categories
Crab Champions spreads its arsenal across a handful of clear roles. Knowing the role matters more than memorizing every gun, because it tells you how a weapon wants to be played.
| Category | Examples | Role | General strength |
|---|---|---|---|
| Automatic / rapid-fire | Auto Rifle, Minigun, Auto Shotgun | Sustained DPS, forgiving aim | High and reliable |
| Projectile launchers | Blade Launcher, Orb Launcher, Cluster Launcher, Rocket Launcher | Burst and crowd clearing | High with the right mods |
| Precision | Sniper, Crossbow | Single-target, boss damage | Spikes hard vs tanky targets |
| Pistols | Burst Pistol, Dual Pistols | Mobile, close to mid range | Solid, build-dependent |
| Shotguns | Dual Shotguns | Close-range bursts | Strong up close, weak at range |
Automatics are the safe backbone of most builds. They keep damage flowing while you concentrate on movement and dodging, which in a fast platforming shooter is half the battle. Launchers trade that steady stream for bigger, splashier hits — great for groups and for melting a target quickly, but they ask a little more from your aim and positioning. Precision weapons are the specialists: they can feel underwhelming against swarms but come alive against the tanky bosses that decide whether a run survives. Pistols and shotguns round things out with mobile, aggressive options that reward getting in close.
Standout weapons and why
A few weapons come up again and again in community discussion. Treat the names below as informed opinion rather than fact — they reflect how the game has played across recent balance, and Early Access means any of this can shift in a patch.
This tier overview is community-informed opinion for the current Early Access balance, not a definitive ranking. Noisestorm adjusts numbers patch to patch, and a weapon's placement can swing once you stack the right mods and perks. Use it to decide what to try first, then trust what actually performs in your own runs.
The Minigun earns its reputation honestly: a large magazine plus continuous fire means you rarely stop dealing damage, which is exactly what a movement-heavy game rewards. The Blade Launcher and Orb Launcher are the launchers people gravitate toward because their projectiles do reliable work and respond well to mods that boost projectile speed or add area effects. The Sniper is the clearest example of a situational standout — it can feel slow against early swarms, but with crit and fire-rate behind it, it tears through the tanky bosses that end most runs.
The dual-wield trade-off
Dual Pistols and Dual Shotguns are the game's dual-wield options, and they carry one important catch worth understanding before you commit. Dual weapons cannot aim down sights, which means you lose the aim slow-down effect that single weapons give you when you scope in. That slow-down is a real aiming aid, so giving it up changes how you play.
If you take a dual weapon, plan to fight aggressively and up close where raw output matters more than careful aim. If you prefer to line up precise shots — especially with precision weapons against bosses — a single weapon and its aim slow-down will serve you far better. Match the weapon to how you actually like to move and shoot.
In practice this makes the dual options feel great in chaotic, close-range arenas and noticeably worse when a boss wants you to place shots from distance. Neither is wrong; they are simply built for different moments. Knowing the trade-off up front stops you from blaming the weapon for a mismatch you can avoid.
How mods and perks change the answer
The reason no weapon is permanently "best" is that mods and perks reshape everything. With 89 weapon mods in play, a gun's behavior and damage can change dramatically over a run — projectile speed, spread, damage auras and more all stack into your foundation. A weapon that feels flat at the start can become your carry once it picks up the right mods, and a strong base weapon can stall if the offered mods never line up with it.
Perks layer on top of that. A Sniper paired with crit and fire-rate is a different weapon than a Sniper without them, and launchers swing wildly depending on whether your mods favor area, speed or raw damage. The Anvil mechanic interacts with your upgrades too, giving you another lever on how a run develops. The takeaway is simple: pick a weapon you understand, then stay flexible and let the mods you actually find steer the build. For deeper synergies, see the builds guide.
Beginner-friendly picks
If you are still learning the movement, dodging and arena flow, you want a weapon that does its job without much babysitting. The Auto Rifle is the starter for good reason — it is reliable, forgiving and lets you focus on staying alive rather than managing your gun. The Minigun is the natural next step: its sustained fire keeps damage flowing while you concentrate on positioning.
Hold off on the precision weapons and dual-wield options until you have the basics down. The Sniper and Crossbow reward aim you may not have yet, and the dual weapons give up the aim slow-down that beginners lean on most. Start steady, learn how mods change your run, and branch out once you trust your movement. For the wider fundamentals of a run, the beginner guide covers what to do beyond the weapon select.
Honest takeaway
Crab Champions makes its weapon choice feel weighty precisely because you commit to it, but the mod system keeps any single pick from being a trap. The community favorites — Minigun, Blade Launcher, Orb Launcher — are favorites because they are forgiving and scale well, and the Sniper remains the answer when bosses get spongy. Since this is Early Access, none of that is set in stone. Pick something that matches how you like to play, learn how it responds to mods, and let your own runs be the final tier list.
