Armored Core 6 players hit with intense emotional whiplash as new patch buffs nearly ever weapon but nerfs beloved shotgun and grenade cannon

They had it coming.

From the moment players started blasting their way through Armored Core 6 dual-wielding the Zimmerman shotguns with two Songbirds grenade cannons on their shoulders, it seemed like only a matter of time until FromSoftware took a long, hard look at each weapon and turned down the heat on them both. Heck, after the last patch in early September, it became a community meme that the Zimmerman escaped unscathed. That dominant run ended today with patch 1.03.1, which buffs dozens of weapons and other mecha parts while laser targeting a few nerfs at AC6's most powerful guns.

FromSoftware clearly decided a few weapon types were underperforming and gave them across-the-board improvements. Four bazookas, for example, now have increased projectile speed and faster reloads. Four handguns have increased rounds, making them more viable picks for longer missions.

Many other weapons have gotten similar treatment, either seeing increased ammo counts, decreased reload times, or faster charge attacks. Only a few specific weapons have seen nerfs, including the fan-favorite Zimmerman shotgun and the Songbirds grenade cannon. Here's the text straight from the patch notes: 

Armored Core 6 players quickly loaded up the new patch to determine exactly what's changed, and redditor UmbraBliss did us all a solid by sticking the new stats next to pictures of each weapon to make the changes easier to digest.

The Zimmerman shotgun has seen an 11% nerf to damage and a bigger 26% nerf to impact (which fills an enemy's stagger gauge). 

The Songbirds grenade cannon has taken a similar hit, with a roughly 13% damage cut and 12% nerf to impact. Both weapons also saw nerfs to their accumulative impact, which is how long their stagger
