To earn all achievement rewards in the Mecharashi Reversion Paradox event stages—Story 8 ("Under The Knife") and Story 10 ("Break Time")—commanders must focus on tactical positioning, lane control, and specific unit loadouts to satisfy stage objectives without exceeding turn limits.
Story 8: Under The Knife Tactics
Story 8 requires strict lane control to protect secondary objectives and manage incoming enemy fire. Avoid charging directly into the center of the map immediately, as overextending allows enemy units to secure defensive terrain buffs and stall your team past turn limits.
- Flank Deployment: Place high-mobility units along the outer flanks. This placement ensures they can intercept incoming enemy reinforcements immediately upon spawning and reach extraction or objective points before the stage ends.
- Lane Control: Prioritize killing specific threat units in secondary lanes first. Keeping lanes clear prevents enemy forces from flanking your squad and overwhelming your main formation.
- Target Selection: Focus fire on enemy units that grant defensive or offensive buffs to their allies to prevent stall tactics.
Story 10: Break Time Positioning
Story 10 shifts the challenge toward managing dense enemy waves in later turns. Because late-stage enemies utilize area-of-effect (AoE) abilities, grouping units together leads to heavy damage across your lineup.
- Adopt a Staggered Formation: Place high-durability tank units forward to draw enemy aggro, keeping high-DPS attackers separated in backline positions out of AoE range.
- Utilize Defensive Terrain: Move pilots onto tiles offering natural terrain modifiers. These tiles increase evasion and hit rates while boosting defense, reducing the need to spend turns using repair abilities.
- Conserve High-Impact Skills: Finish off low-health targets using standard attacks, reserving ultimate abilities for elite units and bosses.
Achievement Preparation and Loadout Adjustments
Securing full clear achievements requires checking mission criteria before making your first move. Common failure points stem from unoptimized gear or ignoring secondary conditions.
| Strategy Focus | Recommended Setup & Action | Tactical Purpose |
|---|---|---|
| Gear Selection | Equip armor-piercing weapons or backpacks | Bypasses high enemy armor ratings to maintain high damage output per turn. |
| Action Economy | Deploy pilots with extra action or move-and-attack skills | Maximizes actions per turn to meet strict time and turn count limits. |
| Condition Check | Review secondary objective requirements before turn 1 | Prevents accidental failures on conditions such as zero unit losses. |
