SANABI A Haunted Day Guide: Major Song's Controls, 2 Bosses, and 4 Achievements

A Haunted Day is free additional content requiring the main SANABI game. Steam lists November 26, 2025 as its release date, while the Japanese release announcement is dated the following day, November 27. It takes place 13 years before the main story and stars Major Song.

Select the spin-off separately from the main walkthrough's Chapters 0–5, and check your episode and difficulty. Steam's current 21 achievements include 4 spin-off additions; do not mistake the absence of achievements under the DLC's own app ID for zero spin-off achievements.

You move opposite the direction you fire. Treat midair slashes and recoil as resources for reaching the next foothold.

Using both jumps and the shotgun immediately can leave you unable to continue even if you reach an enemy midway. Treat slashable enemies and cranes as replenishment points along the route.

1. First identify the landing floor/wall and targets you can slash along the way.
2. Approach a target with the first jump and land a midair slash.
3. Use replenished aerial actions to reach the next target.
4. Save the second jump and shotgun recoil for the final ledge, reaching the wall.

Specific keys and input windows differ by platform/bindings, so prioritize the in-game display.

These are major confirmed progression points. Use them to identify your current scene, rather than as a complete walkthrough listing every scrapyard room and route.

The spin-off's first boss is a changed form of the main game's giant mechanical worm. Finish the chase, enter the arena, and attack while avoiding falling scrap and added enemies.

A bright panel is exposed on the machine's front at some points, and scrap sometimes forms high footholds. Do not assume staying on top is safe; watch the machine's destination and your next escape.

After depleting the durability gauge, check the support team's blackout message and the change to the machine's front. Continue attacking the brightly exposed frontal weak point until the machine breaks and the next scene begins. Do not mistake the displayed HP-healing action for the machine's power switch.

1. During the chase, link movements to the next safe wall or floor.
2. In the arena, do not remain where additional enemies or falling objects arrive.
3. Separate aerial movement actions from enhanced shots, and attack the exposed front.
4. After the blackout message, aim again at the bright frontal weak point. If extra enemies and projectiles remain below, approach while avoiding them.
5. After attacking the weak point in midair, use the replenished jump for your next escape. See the update differences below for the old replenishment bug.
6. Confirm the machine's chain of explosions and scene transition, then proceed to Prototype and the next area.

The public PC Dark Horse playthrough confirms the blackout message → frontal attacks → destruction → next area. No fixed hit count for every difficulty, or claim that only one attack type works, is asserted.

This table checks entrance terrain and what to use next. Numbers indicate this guide's reading order, not in-game stage numbers. It does not list every small room in normal sections; confirmed difficult points are grouped before the chase, during it, in the depths, and near the end.

Use your currently assigned healing action for the spin-off's HP-recovery prompt. Even if the PC default example shows E, not every platform or remapped input uses E.

These points differ between November 2025 gameplay and later fixes. Update numbers identify the fixes checked; they do not assert that every platform received the same build number simultaneously.

Bulgasal combines turrets, electricity, and lightning strikes in the second half. Do not assume Burst removes every projectile; leave room to dodge projectiles and lasers it cannot cancel.

In the first half, thick turrets increase danger through projectiles and extra enemies. If enhanced shots are available, prioritize clearing them and open an aerial escape before danger builds.

The second half also requires responding to lightning. Do not immediately spend every enhanced shot purely for damage; save them for situations where you need to evade lightning. Do not predict enemy projectile patterns using fixed probabilities.

Check main-game Legend completion separately from the spin-off's highest difficulty. If difficulty translations differ, identify the top mode on the spin-off selection screen.

Covers aerial actions, progression milestones, 12 specific difficult points, 2 bosses, and 4 achievements. The first boss now includes frontal weak-point attacks after the blackout and the connection after destruction.

The connection order of every small room in every normal stage, and the full placement of all targets in each room, remain incomplete. Scene-by-scene viewing of public gameplay is distinguished from continuous viewing of the entire video; this is not presented as a complete spin-off walkthrough.
