SD Gundam G Generation ETERNAL UR V2 Assault Buster 4-Action Guide

In SD Gundam G Generation ETERNAL, the UR V2 Assault Buster can take up to four actions in a single turn and fire two wide-area MAP attacks by chaining Chance Step resets off confirmed enemy eliminations. To execute this rotation successfully, you must sequence attacks from weakest to strongest targets so the unit never stalls on a surviving enemy.

The 4-Action Rotation Sequence

A Chance Step triggers only when the active unit completely destroys a target, granting an additional movement and attack phase up to the suit's limit. Leaving an enemy alive with any amount of remaining HP immediately ends the chain.

Follow this target order to complete the full four-action sequence:

1. Action 1 (Initial Step): Advance and attack an isolated, low-HP minion using a low-cost, long-range standard weapon. Confirm the kill to activate Chance Step 1.
2. Action 2 (First MAP Weapon): Move into the main enemy cluster and position the unit to catch multiple low-to-medium health targets within the wide MAP weapon footprint. Fire the MAP attack to wipe out the fodder and soften tougher foes, triggering Chance Step 2.
3. Action 3 (Second MAP Weapon): Reposition along the grid to catch a secondary cluster or remaining damaged units. Launch the second MAP attack or a heavy ranged skill to clear remaining grunts, triggering Chance Step 3.
4. Action 4 (Elite or Boss Target): Use your final action to burst down an elite unit or boss, or retreat into a safe defensive position if no lethal target remains.

Managing Energy Across the Rotation

Firing two MAP attacks alongside movement and standard strikes puts immense pressure on your energy (EN) pool. Running out of EN mid-turn leaves the unit stranded deep inside enemy lines without defensive counterattack capability.

To avoid draining your pool completely, support the V2 Assault Buster with squad members that provide passive EN restoration or keep the unit within range of warship recovery. Avoid opening the turn with maximum-cost single-target EX skills so you preserve sufficient EN for both MAP activations.

Pilot Synergy and Target Suitability

Pair the V2 Assault Buster with pilots who accelerate Morale gains and boost ranged burst output:

• Canonical Pairing: Uso Ewin provides natural affinity benefits and strong stat scaling for the suit.
• Pilot Skills: Prioritize traits that offer starting Morale bonuses, critical hit rate increases on multi-target attacks, or EN consumption reductions. Reaching Super High Morale (Tension) early ensures your MAP attacks cross lethal thresholds against neutral-affinity targets.

When to Deploy

• Ideal Stages: Mob-dense story chapters, multi-wave resource farming stages, and tower challenges featuring wide grids and enemy swarms.
• Avoid: Single-target raid bosses with multiple break bars. Because the four-action rotation relies entirely on securing unit kills to trigger Chance Steps, a lone target prevents the unit from extending its turn beyond standard limits.
