Autumn Equinox Fortress Warfare Build Basic Info

The Way of Winter's Autumn Equinox Fortress Warfare Build is a high-octane, crit-focused machine, designed to punish enemies with relentless damage while keeping you and your team safe. At the core of this build is the M416 - Autumn Equinox, a powerhouse assault rifle that thrives in the chaos of Fortress Warfare. It triggers Fortress Warfare after a few hits, creating an area that grants your allies Heavy Armor for a short time, boosting both their defense and damage. While inside this zone, you’ll recover a chunk of your HP per second, keeping you in the fight while your crits stack up. Plus, if your HP is above 75%, you get an additional 25% Weapon DMG boost.

To get the party started, you’ll use the AWS.338 - Bullseye to butter up enemies from a distance, marking them with a weakened target for maximum vulnerability. Once they’re all marked and vulnerable, you swap to your M416 - Autumn Equinox and activate Fortress Warfare. With your enemies soft and your teammates armored, it’s time to mow them down while staying healed, boosted, and ready for the next round of destruction.

Best Weapons for Autumn Equinox Build in Once Human

Primary Weapon: M416 - Autumn Equinox

The M416 - Autumn Equinox is the cornerstone of this Fortress Warfare build. With the power to trigger Fortress Warfare after 7 hits, you create a protective zone that not only grants your allies Heavy Armor but also lets you recover 4% of max HP per second—talk about staying power!

When your health is above 75%, you unlock a fantastic 25% boost to Weapon DMG. So not only are you fortifying your team with Heavy Armor for a full 5 seconds, but you're also ramping up your own damage output by 20%.

Combine this beauty with the Bastille Set and the right mods for a dynamic synergy that elevates your support role to legendary status. You’ll be healing yourself while dishing out damage, ensuring your allies are well-protected and ready to unleash their own fury.

Go with Rapid Shot Style Calibration.

Secondary Weapon: AWS.338 - Bullseye

The AWS.338 - Bullseye is your perfect wingman for the M416 - Autumn Equinox. With a 70% chance to trigger The Bull's Eye on weakspot hits, it outlines and weakens targets for 12 seconds, softening them up for the M416’s finishing blows. Plus, your first shot after switching weapons guarantees Bull's Eye, so you’re always ready to mark high-priority enemies.

Each weakspot hit also boosts Weakspot DMG by 15% (stacking up to 3x), and if you take down a marked enemy, you get +15% Attack for 20 seconds. It's the ideal partner for making enemies vulnerable and primed for the M416 to sweep them away.

Melee: Long Axe

The Long Axe is the ultimate melee sidekick for the Autumn Equinox build! Every heavy hit activates Fortress Warfare, giving your squad Heavy Armor every 10 seconds. Plus, each target you hit boosts your Crit Rate and Swing Speed—stacking up to 3 times. Swing big, get tougher, and set the stage for your M416 to mop up the battlefield!

Oh, but if you find yourself turning into a popsicle in the Snowy Realm's chilly climate, then by all means, swap that mighty Long Axe for a Torch. Totally not a desperate move... really, no shame at all.

Lonewolf Set for Face, Gloves, Top, and Bottoms

Equipping 4 pieces of the Lonewolf Set (such as the Mask, Gloves, Jacket, and Pants) supercharges your crit power in this Fortress Warfare build. With +10% Magazine Capacity and +5% Crit Rate, you’re packing more rounds and landing crits more often. Plus, every 2 crits stack Lone Shadow, granting +6% Crit DMG for 30 seconds—stacking up to 8 times and maxing at 10!

On each kill, you get a quick +8% Crit Rate boost for 2 seconds, perfect for keeping the damage flowing. This set transforms you into a rapid-firing crit machine, amplifying the M416’s offensive potential.

Bastille Hood for Helmet

Ah, the lovely Bastille! Just a single piece of this beautiful set is a perfect match for the M416 - Autumn Equinox—keep your HP above 75%, and you’ll stack +10% and +25% Weapon DMG boosts for a total of +35%. Stay healthy, hit harder, and watch your enemies fall even faster!

Lonewolf's Whisper

Lonewolf's Whisper (or Canine Skull) is your very own bloodthirsty wolf minion! It chases down enemies, makes them regret ever existing, and when one drops, it just spawns a clone to keep the carnage rolling. Oh, and don’t worry—while it's having its little feast, your target gets an extra dose of pain, boosting the Weapon DMG against it. Who’s a good boy now?
