All main and power weapons in Saros

Saros has over 15 different main weapons and 4 power weapons that you can unlock as you progress through the different biomes in the game. Weapons are usually found in white, red, and yellow locked containers, and you can even re-roll to possibly acquire a weapon you'd like to use in your current run. Here's some information on how to use each weapon in the game and which biome each one starts appearing in.

Unlocking all weapons is one of the requirements for the entire Arsenal trophy Saros. Players must also defeat 25 enemies with each weapon, and a good way to track these kills is by checking a weapon's percentage in the databank and getting them all close to 20%.

All weapons in Saros

Main weapon

Arms	When does it unlock?	How does it work?
Eruptor Hand Cannon	Shattered Rise (Biome 1)	This weapon features a triple-burst primary fire, while Alt-Fire loads multiple rounds into the barrel to unleash a spray of bullets with high recoil and dispersion.
Ricochet hand cannon	Shattered Rise (Biome 1)	The second hand cannon fires single shots that can penetrate enemies and bounce off walls to hit multiple enemies at once. Its Alt-Fire makes the weapon fire much faster, making it shorter to enemies.
Marksman Handcannon	Shattered Rise (Biome 1)	The only hand cannon without Auto-Hit, this weapon has a triple burst primary fire. However, its Alt-Fire makes the gun more reliable, as you can charge a single power shot that marks an enemy on hit. You can then use your primary fire on the marked enemy without having to worry about the weapon lacking Auto-Hit.
Tactical rifle	Shattered Rise (Biome 1)	Using the primary fire of the tactical rifle, it fires at a normal rate. If you hold down L2 for Alt-Fire, the fire rate increases the longer you hold the button.
Assault rifle	Shattered Rise (Biome 1)	The Onslaught Rifle does not have the Auto-Hit feature. Its primary fire is similar to the Tactical Rifle, but Alt-Fire lowers the rate of fire to double the number of projectiles fired while targeting enemy weak points.
Smart Rifle	Shattered Rise (Biome 1)	A Smart Rifle that fires red-colored projectiles with its primary fire, while Alt-Fire causes the bullets to scatter and land on enemies.
Horde shotgun	Ancient Depths (Biome 2)	The Horde Shotgun has a wide spread primary fire and is a semi-automatic shotgun. Pressing L2 changes the barrel to a vertical spread, allowing you to hit enemies further away with more precision.
Stolen shotgun	Ancient Depths (Biome 2)	This has the same primary fire as the previous shotgun, but Alt-Fire fires a wall of projectiles that slowly move towards an enemy. You can use your primary fire on this wall to make the projectiles move faster.
Annihilator shotgun	Ancient Depths (Biome 2)	This has the same primary fire as the Horde Shotgun, but pressing L2 turns the gun into a grenade launcher. The grenade deals area damage when it comes into contact with a target or surface.
Repeater crossbow	Shattered Descent (Biome 3)	The primary fire in this crossbow shoots a wide bolt. Its Alt-Fire fires a single shot that, when it hits an enemy or terrain, splits into multiple homing projectiles.
Impactor Crossbow	Shattered Descent (Biome 3)	This crossbow has a primary fire where you can charge a volley of bolts and either shoot or release R2 to fire. Holding the trigger longer adds more bolts to the salvo. Alt fire causes the weapon to fire a single projectile that, when it hits an enemy weak point, creates homing projectiles.
Bifuracator crossbow	Shattered Descent (Biome 3)	With the Bifurcator Crossbow, you can charge a shot and fire it by releasing the R2 button or stabbing. If you hold the charge longer, more projectiles will be released and all will land on an enemy. Its Alt-Fire is the same as the Repeater Crossbow.
Ripsaw Chakram	Acolyte's Haven (Biome 6)	Holding R2 on the first Chakram weapon fires discs that embed into enemies. Using Alt-Fire uses the embedded discs to deal constant damage to enemies until they die or you stop using Alt-Fire.
Harvest Chakram	Acolyte's Haven (Biome 6)	The primary fire for this weapon allows you to throw a disc and return it by pressing L2. Holding L2 after the disc returns creates a ring around Arjun that damages nearby enemies.
Myriad Chakrams	Acolyte's Haven (Biome 6)	Myriad Chakram allows you to fire discs quickly using Auto-Hit. Its Alt-Fire disables Auto-Hit, but the discs can target enemy weak points, allowing them to return instantly.

Power weapon

Arms	When does it unlock?	How does it work?
Prominence	Shattered Rise (Biome 1)	Holding L2 and shooting with R2 fires an explosive projectile that damages enemies in a large area and can knock them into gear.
Dispiriter	Ancient Depths (Biome 2)	The second power weapon deals damage over time, as you can constantly aim the swarm of projectiles at multiple enemies. If an enemy dies from this power weapon, they will leave behind a cell that shoots small projectiles around it.
Nova Lance	Attempted Fortress (Biome 5)	You can charge a powerful energy shot by holding down L2 and R2, and when you release it, the shot will penetrate multiple enemies and deal significant damage to weak points.
Enlighten	The Cathedral (Biome 7)	The final power weapon allows you to charge and fire a beam that constantly damages an enemy as long as you have power.

What are the best weapons in Saros?

Saros could follow in Returnal's footsteps in more ways than one

All guns in Saros are pretty good, with a few exceptions, but you can comfortably complete biomes with all of them, especially as you reach the mid to late game. Even so, there are weapons that I would personally rank higher than others, mainly due to their sheer damage and how easy they are to use.

After putting almost 35 hours into the game, three weapons stood out the most to me. Starting from the bottom is Ricochet hand cannon. This is the second weapon you get in the game, and players come from Return who didn't use the pistols much will be happy to hear that the hand cannons are coming in Saros have received the attention they deserve.

The Ricochet Handcannon can clear out rooms in seconds thanks to its penetrating enemy properties. Simply pressing L2 to Alt-Fire and spam shots will damage multiple enemies at once, making most rooms in each biome easy. The only reason the weapon isn't in my top two is because of how it performs against bosses. Since bosses are single targets, you can't really take full advantage of the weapon.

Coming in at number two is Annihilator shotgun. This is another fun weapon to use, and despite that Spitmaw Blaster from Return be more average, shotgun in Saros work a little differently. The primary fire of the Annihilator Shotgun works like any other shotgun, but the Alt-Fire is where the real destruction is. Pressing L2 turns the gun into a grenade launcher that can tear through an enemy's health bar in one or two shots.

Even in boss fights, if you can consistently land the grenades, you'll see the boss's health bar drop extremely quickly, propelling it into the next phase. While aiming the grenade launcher at smaller flying enemies can be a bit difficult, you can still rely on the primary fire in those situations and not worry too much.

My number one weapon is Repeater crossbow. It's easily one of the least complex weapons to use, and not only that, it does most of the work for you. I know this type of weapon might not excite everyone, but that doesn't change the fact that it feels overwhelming to use. The primary fire crushes enemies, and crossbows with higher skill have faster fire rates.

The main reason the weapon is so good is its Alt-Fire, which allows you to aim anywhere on the terrain or ground and still hit multiple enemies at once. Its projectiles can track, meaning they constantly hunt and damage enemies in a room without you having to worry about where they are. In boss fights, the weapon holds up extremely well, and you can always switch to primary fire while mixing in Power Moves, making most boss fights much less challenging.
