Before we dissect the patch notes, it is crucial to understand the scope. Attack on Survey Corps is not an official Koei Tecmo or Spike Chunsoft product. Instead, it is a labor of love by AstroNut, built from the ground up in either RPG Maker MV/MZ or a custom Ren'Py/Battle sim hybrid—depending on which build branch you follow.
The game focuses on the logistics of survival. You do not simply play as Eren, Mikasa, or Armin. Instead, you create a custom Scout Regiment officer. You manage squad morale, gas levels, blade sharpness, and the long-term psychological toll of seeing your comrades eaten by Titans.
Version 0.22.1 is described by AstroNut as the "Stability & Reaction" patch, focusing on two things: glitch elimination and mid-air combat responsiveness. Attack on Survey Corps -v0.22.1- -AstroNut-
AstroNut released the official notes via a cryptic text file. Here are the highlights:

Bug Fixes:
v0.22.1 sharpens Attack on Survey Corps toward a faster, more mobile meta while shoring up stability and mission variety. The patch rewards players who master movement and positional play, revives close-quarters shotgun tactics, and makes enemy encounters more tactically demanding. Overall it’s a confident step forward: less forgiving for passive play, more fun for high-skill, aggressive runs.
If you want, I can:
In previous builds, your ODM (Omni-Directional Mobility) gear had infinite durability. That is gone. In v0.22.1, every swing and grapple reduces an "Anchor Integrity" stat. Let the meter hit zero, and your wire snaps mid-swing—sending you flying into a Titan’s mouth or splatting against a tree. This forces players to think like Levi: short, precise bursts of movement rather than constant aerial flailing.
