NotesEdit
- Despite the appearance of its shots, the Dual Decurion is a hitscan weapon.
- The Dual Decurion's smaller magazine makes it easy to run out of ammo in a gunfight, but its quick ammo recharge balances this out.
- A good way to maintain ammunition supply is to fire in bursts of 2-8 bullets.
- Its component parts are listed in Offerings as "Decurion" parts, and Dual is not in the parts' name.

Update 24.2
‘ATMOSPHERE’ ARCH-GUN WEAPONS
It’s time we equipped some serious floor firepower! All Arch-Guns can be used on the ground - or as we like to call it ‘Atmosphere’ - with the use of a ‘Gravimag’. Gravimag is obtained from Clan Research, or as a one-time reward from the Orb Heist Phase 3 Bounty, and can be installed on any Arch-Gun (with an Orokin Catalyst installed) via the Upgrade Arsenal - similar to installing a Catalyst.
Comparable to the Archwing and K-Drive Launchers, a respective Gear item known as the Archweapon Deployer is required to activate your Atmosphere Arch-Gun. The Archweapon Deployer can be obtained by completing the Orb Heist Phase 3 Bounty.
Atmosphere Arch-Gun General Changes:
- Atmosphere Arch-Guns consume Ammo as opposed to unlimited Ammo/Battery in Archwing. Specifically new Heavy Ammo Drops which can be found from Corpus enemies in Orb Heist missions. Heavy Ammo Drops also reset the 10 minute cool-down when picked up, or replenish Ammo if needed.
- Atmosphere Arch-Gun can be summoned in normal missions with the Archweapon Deployer, but once Ammo has been depleted there is a 10 minute cool-down until you can summon again. The intent here is to allow you moments of beefy damage output, and not become just another Primary/Secondary weapon.
All stat changes are for Atmosphere Arch-Gun mode, Mastery Rank changes are global:
- Mastery Rank increased from 0 to 1.
- Damage increased from 60 to 110.
- Critical Chance increased from 25% to 28%.
- Critical damage increased from 2x to 2.2x.
- Status Chance increased from 10% to 14%.
- Ammo Capacity set at 256.
- Reload speed set at 1.4 seconds.
- Introduced.
