SD Gundam G Generation ETERNAL: Audrey Tower 15F Clear Guide

To clear Audrey Tower 15F in SD Gundam G Generation ETERNAL, ignore Mr. Bushido and focus all offensive firepower on destroying the Lohengrin Cannon. The stage ends immediately when the cannon is destroyed, making total enemy elimination unnecessary. Deploy a dual-tank frontline to intercept flanking attacks and hold the narrow canyon corridor while your offensive units advance into firing range.

Lohengrin Cannon Win Condition and Enemy Traps

Audrey Tower 15F recreates the canyon battle from Mobile Suit Gundam SEED DESTINY, restricting movement to a narrow gorge flanked by impassable terrain. Enemy placements are designed to delay your advance and force an extended battle of attrition under artillery fire.

Mr. Bushido acts as a diversionary threat on the flank. He features high durability, elevated combat stats, and dangerous counterattack potential. Trading blows with him expends actions and EX gauge charges without contributing to the victory condition. Treat him and the ambient canyon grunts purely as obstacles to block rather than targets to eliminate.

Squad Formation and Role Distribution

Fielding two dedicated defensive units ensures incoming fire is split across two separate durability pools, preventing your forward line from collapsing under combined boss and grunt attacks.

Squad Role	Placement	Target Priority	Tactical Function
Main Tank	Front-Left Flank	Mr. Bushido	Intercepts Bushido's advance and absorbs heavy single-target strikes.
Off-Tank	Center Choke Point	Canyon Grunts	Blocks the gorge pathway and prevents grunts from reaching damage dealers.
Burst DPS	Midline	Lohengrin Cannon	Conserves EX skills until within direct striking range of the battery.
Ranged Support	Rear Column	Lohengrin Cannon	Buffs ally range or snipes the cannon from outside hostile threat zones.

Step-by-Step Canyon Assault Route

Execute the push through the gorge over three coordinated phases to reach the battery without losing offensive units.

Turn 1: Isolate Flank Threats and Set the Choke Point

Move your main tank into the front-left lane to trigger Mr. Bushido's aggro while keeping fragile units outside his attack range. Move the off-tank down the center of the canyon to engage the first wave of grunts. Position damage dealers directly behind the off-tank, out of enemy firing lanes.

Turn 2: Secure the Passage

Trigger defensive skills or guard stances on both tanks. The main tank locks Mr. Bushido along the outer ridge, while the off-tank holds the central line. Advance your damage dealers past the engaged frontline into striking range of the Lohengrin Cannon.

Turn 3: Burst Down the Lohengrin Cannon

Ignore remaining grunt units and disengage from Mr. Bushido. Unleash reserved commander abilities and EX skills directly on the Lohengrin Cannon to destroy the objective before your tanks succumb to sustained enemy fire.

Spacing Discipline and Execution Pitfalls

Because this strategy dedicates two squad slots to pure defense, your remaining offensive units must possess sufficient weapon upgrades, terrain scaling, and offensive pilots to destroy the cannon before defensive cooldowns run out.

Maintain strict unit spacing throughout the push:

Do not cluster tanks together or place damage units within two tiles of the frontline, as enemy area-of-effect attacks can bypass tank positioning.
Keep the main tank isolated on the left flank to prevent Mr. Bushido from cleaving into your center column.
Keep damage units trailing at maximum weapon range until ready to commit their full burst rotation on the cannon.
