SD Gundam G Generation ETERNAL Secret Stage Auto-Clear Guide

To clear Secret Stage missions on auto in SD Gundam G Generation ETERNAL without losing units or missing turn limits, configure your squad around standardized 3–5 tile weapon ranges, strategic deployment tile placement, and passive pilot buffs. The automated battle system attacks the closest target with its highest-damage weapon, ignoring counterattack risks. Structuring your team around these AI behaviors ensures three-star mission clears—beating the turn timer, defeating target commanders, and suffering zero casualties—without manual intervention.

Optimize Starting Deployment Slots

Auto-battle movement paths depend heavily on starting deployment slots. If short-range units with average mobility start in forward positions, they immediately advance, clog movement lanes, and prevent ranged units behind them from acquiring targets.

Arrange your squad on the grid to keep lanes open and establish clear targeting priorities:

Placing forward attackers with clean sightlines allows the AI to focus fire on the nearest enemy cluster. This wipes out initial waves before the enemy turn begins, sharply reducing incoming damage.

Standardize Weapon Ranges and Resource Bulk

Weapon reach dictates how far forward automated Mobile Suits push into hostile fire:

• Enforce 3–5 Attack Range: Melee units limited to 1–2 tiles force the AI to close into point-blank range, leaving them exposed to multiple retaliatory attacks during the enemy turn. Equipping units with 3–5 tile weapons—such as beam rifles, mega particle cannons, or missile pods—lets units attack from outside standard retaliation envelopes.
• Maintain Deep EN Reserves: Automated units default to the highest-damage attack available, burning through energy rapidly. Field units with high base EN pools or energy-reducing pilot skills to prevent them from falling back on low-damage, short-range basic attacks.
• Raise Defensive Thresholds: Ensure all frontline and mid-range suits have adequate terrain ratings and defensive stats so unavoidable enemy phase counterattacks deal negligible damage.

Equip Passive Skills and Warship Auras

The auto-battle system triggers active pilot skills reactively, often wasting high-value offensive buffs on weak grunts. Build pilot and crew loadouts around passive bonuses that function automatically every turn:

• Pilot Passives: Prioritize flat stat increases, unconditional critical hit bonuses, and damage-reduction traits active above designated health thresholds. These passives boost performance during both player and enemy phases.
• Warship Captain: Deploy a captain with high command stats. A wider command area provides consistent squad-wide hit rate and evasion bonuses across the field.
• Bridge Crew: Staff bridge stations with crew members who boost general attack and defense stats to help your units score clean eliminations against bulky commanders.

Step-by-Step Auto-Clear Setup

Before setting a stage on repeat auto-battle, run a trial clear to check for lane congestion or unexpected damage spikes:

1. Verify Mission Objectives: Check the stage's star conditions, including turn count caps, commander kill targets, and squad survival rules.
2. Align Attack Ranges: Adjust your Mobile Suit loadouts so active units operate comfortably in the 3–5 tile band.
3. Set Starting Grid Positions: Place your highest-mobility ranged attackers in forward slots and place durable anchor units in central or rear slots.
4. Run an Unskipped Test Battle: Watch one run at normal speed to observe movement bottlenecks, energy consumption, and enemy counterattack patterns.
5. Replace Fragile Units: If any unit drops into critical health or gets stranded away from support auras, swap it for a sturdier or faster alternative.
