Alpha Signal Mission Guide in Stellar Blade

This comprehensive guide will walk you through the mission, providing detailed information on key locations, collectibles, and boss fight strategies.

Step 1: Matrix 11 – The Starting Point

Upon arriving at Matrix 11, you will find a Supply Camp. Interact with it to discover the Great Desert Crossing Exploration Team Advertisement Document in the nearby Payphone. After making the necessary preparations, use the improvised ramp on the right to exit the building’s roof and head towards the underground entrance.

Before descending the lift, explore the bathroom on the right to find a body containing the Memory Stick The Last Theorem of An Unknown.

Step 2: Closed Off Platform

In the Closed Off Platform area, you will encounter a new enemy type, the Skulling. These squid-like creatures can be easily defeated using ranged weapons. As you progress, keep an eye out for collectibles, such as the Black Box containing Earrings, Blue Point, and the Document Transport Delay Notice.

To create a shortcut back to the entrance, open the door indicated by Adam. Proceeding further, you will face Skull Troopers, a powerful enemy wielding a large hammer. Use the surrounding environment, such as climbing platforms, to gain an advantage in combat.

Step 3: Landfill

In the Landfill area, you must obtain a passcode from a fallen Legionaire to open a locked supply box containing a Fusion Cell. Use the lift to reach the upper floor and insert the Fusion Cell into the Fusion Drive to unlock the gate leading to the Rail Bridge.

Step 4: Collapsed Rail Bridge

Travel the Collapsed Rail Bridge by using the broken stringers and hanging ropes. Be prepared to react to button prompts as debris begins to fall. At the top of the bridge, make your way through the broken trains until you reach the end of the railway.

Descend the ladder and follow the path to a camp with hanging fairy lights. Before proceeding, explore the area for valuable collectibles, such as the Memory Stick Alex’s Memory, a Body Core, Adam’s Chameleon outfit, and other items.

Step 5: Boss Fight – Stalker

Engage in a challenging boss fight against the Stalker. This enemy uses a combination of ranged projectiles and melee attacks. Use strategies such as dodging yellow attacks, using combat items like Shock Grenades. Here is the breakdown of Stalker’s attacks:

After defeating Stalker, you will receive these items as rewards:

The Burst Skill is a new set of abilities that you can get by pressing R1 and a button (▢, O, △, or X), similar to Beta Skills. However, you must unlock these abilities.

Step 6: Rail Yard Puzzle

In the Rail Yard, solve a short puzzle to discover the train code required to progress. Move the train to the correct position and spray water to reveal the passcode: N72R5.

Before leaving the area, explore the surroundings for additional collectibles, such as a Tumbler Expansion Module and a can.

Step 7: Underground Sewer

Navigate the Underground Sewer, obtaining passcodes and Fusion Cells along the way. Complete a mini-game involving pipes to create a path from the top-left node to the bottom-right node, allowing the liquid to flow correctly.

As you progress, the area will become flooded. Dive underwater to discover hidden collectibles, such as a Beta Core and the Document To the Little Drone.

Step 8: Rotten Labyrinth

In the Rotten Labyrinth, you will encounter Mites and their evolved form, the Mutated Mite. Explore the area thoroughly, uncovering hidden paths and collectibles, such as the Memory Stick Pascal’s Warning and the Daily Force outfit.

Eventually, you’ll reach a survivors’ shelter filled with lore-rich documents and items. Interact with objects like a guitar to learn more about the world of Stellar Blade.

Step 9: Boss Fight – Juggernaut

Face off against the formidable Juggernaut, a larger version of the Skull enemy wielding a massive hammer. Utilize the recently acquired Burst Skills to gain an advantage in battle. Be cautious of the Juggernaut’s fire-infused attacks during the second phase of the fight.

Attack	Description
Hammer Drag Attack	A single-blow attack dragging the hammer, ending in one blow. The combo starts with a regular blow but ends with a pink attack.
Yellow Moves	Side blow followed by spin with a long pause before second blow; single yellow strike.
Blue Moves	Forward blow; grab.
Three-Blow Combo	Three-hit combo, with third hit being a yellow; dodge backward to avoid.
Buffed Phase	Occurs when Juggernaut loses around 20-30% health; attacks are enhanced, ground slams leave fire pools, and new yellow jump attack introduced.
Red Attack	Five-hit combo: quick one, one-two, pause, final one-two.
Final Sequence	Juggernaut will have a final finishing sequence when life reaches zero.

Defeating the Juggernaut will reward you with:

• Beta Enhancement Gear 2
• Crit Boost Gear 2
• Extreme Nano Elements
• Weapon Core

Step 10: Graveyard

The Train Graveyard presents a flooded station filled with containers and wagons. Navigate the area cautiously, as enemies can ambush you from unexpected locations.

Ascend the flight of stairs, defeating enemies along the way, and unlock the Supply Camp at the top to prepare for the final boss fight.

Step 11: Boss Fight – Tachy
