SD Gundam G Generation ETERNAL: 00 Hard 4 3-Turn Dual Mission Guide

To clear Challenge 00 Hard 4 in SD Gundam G Generation ETERNAL while completing both stage missions in a single attempt, deploy dedicated Mobile Suit Gundam 00 franchise units across two strike squads and eliminate the boss within three turns. Splitting your forces covers both spawn lanes immediately, while aggressive counterattacks and Chance Step activations keep your units advancing each phase.

Squad Setup for Two-Flank Coverage

Deploying dedicated Gundam 00 suits grants the franchise stat bonuses required to punch through the elevated armor values in Hard 4. Dividing your units into two complementary strike teams prevents unengaged turns on split spawn maps.

Squad Role	Team 1 Focus (Left Flank)	Team 2 Focus (Right Flank)
Primary Attacker	High-mobility melee burst (e.g., 00 Gundam, Exia variants)	Long-range artillery (e.g., Cherudim, Dynames)
Secondary Attacker	High-evasion skirmisher (e.g., Kyrios, Arios)	Heavy armor breaker with AoE (e.g., Virtue, Seravee)
Support / Utility	Movement range buffs or morale generation	Defense debuffs or critical damage buffs
Warship Position	Wide command radius for linked fire	Forward positioning to extend strike range

3-Turn Combat Sequence

Because the turn limit is rigid, avoid defensive stalling or evasion maneuvers during enemy phases. Rely on full-power counterattacks to whittle down enemy health pools between player turns.

Turn 1: Secure Opening Kills and Push Forward

Initiate on the Left Flank: Send Team 1's lead melee unit to attack the nearest enemy vanguard. Score an immediate kill to trigger Chance Step, gaining extra movement tiles toward the center.
Support and Clean Up: Move Team 1's secondary skirmisher within the lead unit's command area. Use secondary weapons or linked support attacks to eliminate remaining frontline grunts.
Engage the Right Flank: Advance Team 2's ranged artillery to maximum engagement distance. Use piercing or heavy armaments to weaken armored targets and clear shields.
Enemy Phase Counterattacks: Station your forward units directly within enemy threat ranges. When attacked during the enemy phase, select counterattacks instead of evasion to wipe out aggressive units before Turn 2 begins.

Turn 2: Collapse the Midfield Line

Target Surviving Elites: Use Team 2 to snipe high-durability enemies from range. Trigger Chance Step upon each elimination to pull artillery units closer to the central sector.
Breach the Inner Perimeter: Push Team 1 into the sub-commander zone. Clear mid-tier targets using basic attacks or standard skills, conserving energy and EX gauges for the final turn.
Position Aura Buffs: End Turn 2 by placing warships and support units within two to three tiles of the incoming boss spawn area so damage buffs and linked attack radii are active for Turn 3.

Turn 3: Break Defenses and Execute the Boss

Strip Mitigations: Open the assault with Team 2 from outside the boss unit's retaliatory range. Apply defense-down debuffs and strip remaining barrier layers without taking counter damage.
Trigger Pilot Buffs: Activate all offensive pilot skills that increase critical strike chance, raw attack power, or weapon damage multipliers.
Land the Final Burst: Move Team 1's primary melee ace into position within your support auras and unleash your strongest EX attack. Combined with defense shredding and cross-unit link attacks, this sequence depletes the remaining boss health pool to secure both mission clears before the turn expires.
