Best Primary Weapon

Riot Gun

A two-handed shotgun designed for riot suppression. Developed by Jann and Lobell and based on the UJC Modular Weapons Platform.
Type	Primary
Acquisition Type	Default Weapon
Print Price	N/A
Base Ammo Capacity	4

The Riot Gun is our pick for the best primary weapon in The Callisto Protocol. You receive this gun after meeting up with Dani Nakamura at Garage Airlock N107 in Chapter 5: Lost.

Since the Riot Gun deals massive damage up close, it pairs incredibly well with the game's abundance of close-range enemy encounters and boss fights.

In addition, its final Explosive Rounds Upgrade improves the Riot Gun's versatility by giving it an Alt Fire that excels at clearing out crowds of Biophages.

Best Sidearm

Skunk Gun

A prototype one-handed shotgun currently being tested in Black Iron. Developed by the Io Armaments Skunkworks Division.
Type	Sidearm
Acquisition Type	Printed at the Reforge Station
Print Price	800 Credits
Base Ammo Capacity	2

The Skunk Gun is our pick for the best sidearm in The Callisto Protocol. You can find the schematic for this weapon as early as Chapter 3: Aftermath.

While it lacks the range and versatility of the other sidearms, it more than makes up for it in its incredible close-range damage output and ability to combo well with melee attack chains.

Make sure to grab the High Capacity Magazine Upgrade and Stability Upgrade for this weapon to improve its strength and reliability as you progress through the game.

Best Melee Weapon

Stun Baton

A kinetic energy capacitor issued to all Black Iron Security Personnel. Designed to work in conjunction with the UJC Modular Weapons Platform.
Type	Melee
Acquisition Type	Default Weapon
Print Price	N/A
Base Ammo Capacity	N/A

The Stun Baton is the best melee weapon in The Callisto Protocol, received during Chapter 2: Outbreak.

It deals considerably more damage than the Crowbar found earlier in the chapter, and can even be fitted with upgrades to improve its power.

Try to pick up the Stun Baton's Riot Control Swing and Block Break upgrades as soon as possible to make it even more versatile and reliable in close-quarters combat.
