| Harpoon Gun | Advanced | Precision specialist | Calculated boss fights and high-damage single shots |
Weapon balance can shift with future balance patches, but core weapon roles remain consistent throughout Update 1.3. Always choose a weapon that matches your preferred movement and engagement style [00首页信息-1].
S-Tier: The Run Carries
These weapons offer the highest baseline power and scale exceptionally well into the late-game stages of an expedition. They are highly versatile and fit easily into almost any team composition.
- Tesla Gun: The absolute king of crowd control. It fires electrical streams that automatically arc between nearby enemies, making short work of massive swarms [00首页信息-1].
- Brine Revolver: A high-precision weapon that rewards accurate shots. Its high critical damage multiplier makes it the premier choice for melting boss health bars [00首页信息-1].
- Plasma Launcher: Fires explosive plasma orbs that deal massive area-of-effect damage. It is perfect for clearing out spawners and locking down lanes [00首页信息-1].
A-Tier: Reliable Performers
These weapons are strong and reliable, though they may require specific mod setups or playstyles to match the raw power of the S-tier options.
- Combat Bow: Excellent for players who prefer to keep their distance. It features a charging mechanic that scales damage and pairs beautifully with stationary turret skills [00首页信息-1].
- Fish Deity: A unique brinepunk weapon that fires specialized projectiles. When upgraded with damage-boosting mods, it can trigger satisfying chain explosions across groups of enemies [00首页信息-1].
- Engine Rifle: The quintessential starter weapon. It is stable, easy to control, and teaches players how to manage heat and reload rhythms without demanding complex positioning [00首页信息-1].
Advanced Tier: Specialist Selections
These weapons have high skill ceilings or rely heavily on specific mod configurations to be effective. They are not recommended for beginners but can be devastating in the hands of an experienced player.
- Shotgun: Extremely powerful up close, but forces you to play in harm's way. Using this weapon requires constant dashing and double-jumping to avoid taking damage [00首页信息-1].
- Disc Thrower: Shoots ricocheting discs that bounce off walls. It requires a solid understanding of room geometry to maximize damage [00首页信息-1].
- Harpoon Gun: Introduced in the Update 1.2 Brinefrost patch, this weapon deals massive single-shot damage but suffers from a long reload time. It requires precise timing and excellent positioning [00首页信息-2].
S-Tier Weapons and Build Loadouts
To get the most out of your S-tier weapons, you must pair them with complementary weapon mods, Ancient Forge upgrades, and elemental Blessings [00首页信息-1]. A successful build relies on synergy, ensuring that your weapon's primary fire triggers your active Blessings as frequently as possible [00首页信息-2].
Tesla Gun Build
- Primary Role: Crowd Control
- Key Mod: Chain Lightning Range
- Best Blessing: Lightning Arcs
- Playstyle: Stay mobile, fire into swarms, and let the electricity chain across the arena.
Brine Revolver Build
- Primary Role: Boss DPS
- Key Mod: Critical Damage Multiplier
- Best Blessing: Ice Freeze / Weak-point Exploit
- Playstyle: Keep your distance, aim for weak points, and freeze high-health targets in place.
Plasma Launcher Build
- Primary Role: Area Denial
- Key Mod: Splash Radius Increase
- Best Blessing: Fire Burn / Explosive Synergy
- Playstyle: Fire into choke points and group enemies together to maximize explosive damage.
In a 4-player co-op squad, coordinate your loadouts. Have one player focus on crowd control with the Tesla Gun, one on boss damage with the Brine Revolver, and another on area denial with the Plasma Launcher [00首页信息-1].
The upgrade system allows you to customize how your weapons behave. By utilizing the Ancient Forge, you can transform standard shooting patterns into specialized combat tools [00首页信息-2].
| Upgrade Type | Content Pool | Primary Focus | Best Pairing Example |
|---|---|---|---|
| Weapon Mods | 54 Options | Direct behavior and firing changes | Increasing projectile size on the Plasma Launcher |
| Ancient Forge Mods | 140+ Options | Skill-enhancing and weapon behavior upgrades | Adding cooldown reduction to the Combat Bow |
| Elemental Blessings | 250+ Options | Status effects (burn, freeze, arc, summon) | Stacking freeze effects on the Brine Revolver |
Combining these three upgrade paths creates a powerful synergy loop. For example, pairing the Tesla Gun with a Weapon Mod that increases arcing targets, an Ancient Forge Mod that boosts ability cooldowns on hit, and a Lightning Arc Blessing turns you into a walking storm that clears rooms in seconds [00首页信息-2].
How to Unlock and Upgrade Your Loadout
Progressing through expeditions and unlocking the full potential of your weapons requires a systematic approach. Follow these steps during your runs to build a weapon loadout capable of tackling elite encounters and bosses [00首页信息-2].
Choose Your Starting Weapon
Select a reliable starting weapon like the Engine Rifle or Brine Revolver before diving into the run. This choice dictates your early-game combat rhythm and positioning [00首页信息-1].
Collect Run Upgrades
As you clear hand-crafted rooms, keep an eye out for upgrade stations, altars, and treasure chests. These resources are essential for purchasing mods and blessings mid-run [00首页信息-1].
Modify at the Ancient Forge
Locate Ancient Forge stations during your expedition. Use your collected resources to apply weapon mods and Forge upgrades, tailoring your weapon to counter the specific enemies in that area [00首页信息-2].
Invest in Meta Progression
Use the resources gathered from both successful and failed runs to upgrade your permanent skill tree. The expanded skill tree in Update 1.3 unlocks new starting options and passive boosts for all weapons [00首页信息-2].
Do not fear failed runs. Roguelite progression means every attempt contributes to unlocking stronger weapons, permanent skill points, and better upgrade stations for future expeditions [00首页信息-1].
Synergy with Blessings and Charms
With over 250 Charms and Blessings available, the build variety is immense [00基础信息]. Blessings attach elemental or mystic effects directly to your primary fire, secondary fire, and active abilities [00首页信息-2]. Charms, on the other hand, act as passive modifiers that alter your overall combat rhythm, such as boosting movement speed or reducing skill cooldowns [00首页信息-2].
To maximize your damage, you should aim to build around a specific archetype. The table below details three powerful archetypes and how to build them.
| Synergy Archetype | Recommended Weapons | Core Blessings | Combat Style |
|---|---|---|---|
| Summoner | Combat Bow, Fish Deity | Ocean Tentacles, Vengeful Spirits | Deploy skills, place decoys, and let summons fight |
| Status Spreader | Tesla Gun, Engine Rifle | Lightning Arcs, Fire Burn | High fire-rate, constant status application, and kiting |
| Burst Punisher | Brine Revolver, Shotgun | Ice Freeze, Shadow Debuffs | Freeze high-health targets, apply debuffs, and land critical hits |
A strong run usually starts with a single repeatable action, such as a high fire-rate weapon or a short-cooldown skill. Stack Blessings and Charms that trigger from that specific action to maximize your build's efficiency [00首页信息-2].
To keep your progression on track, use this checklist of essential milestones to work toward as you play:
Weapon Progression Milestones:
- Unlock all 9 base weapons through run progression and challenges
- Experiment with at least 10 different weapon mods to find your favorites
- Successfully upgrade a weapon at the Ancient Forge to maximum level during a single run
- Max out the weapon-specific nodes in the Update 1.3 skill tree
By completing these milestones, you will develop a deep understanding of how each weapon behaves and how to adapt your build on the fly based on the upgrades you find during a run.
