Mecharashi: How to Get 3/3 Achievements in Return to Base

To unlock all three achievement rewards in the "Return to Base 3/3" story stage of Mecharashi, execute a strict seven-turn tactical deployment that balances rapid forward movement with zero unit losses. You must push damage-dealing units toward the central objective zone immediately, rotate front-line mechs when health drops, and focus your final attacks on the primary terminal objective.

Seven-Turn Stage Breakdown

Completing this story encounter requires managing action points, positioning long-range units safely, and meeting the objective timeline mapped across seven distinct turns.

1. Turn 1 (00:19): Advance your primary damage-dealing mechs toward the central objective zone. Keep support and long-range units slightly behind your frontline to stay outside maximum enemy engagement ranges.
2. Turn 2 (02:12): Focus fire on the guard formation blocking the main path to the base. Target the lowest-health guards first to minimize enemy counterattacks during their turn phase.
3. Turn 3 (03:56): Spread your mechs across separate tiles. Spacing your squad prevents enemy area-of-effect skills from damaging multiple units at once.
4. Turn 4 (05:34): Spend accumulated action points on high-damage abilities. Breaking enemy armor quickly during this push prevents your team from falling behind the required turn count.
5. Turn 5 (06:43): Position repair units behind frontline mechs to restore health pools without exposing healers to direct attack.
6. Turn 6 (08:17): Execute a tank swap if your lead mech reaches critical health. Move the heavily damaged unit back one tile and slide a full-health mech into the frontline slot to avoid squad deaths.
7. Turn 7 (09:19): Direct all available attacks and movement actions onto the primary terminal objective at the base center. Ignore peripheral enemies that do not block movement or threaten a unit shutdown.

Key Requirements and Failure Points

• Turn Timeline Limit: The stage requires clearing the primary objective within seven full turn phases. Spending actions on unnecessary side targets will cause you to exceed the turn threshold.
• Squad Survival Condition: Earning full achievement credit requires completing the stage without losing a single mech. If an enemy focuses down a weakened unit, rotate that unit back immediately.
• Target Prioritization: Frontline guards must be cleared quickly during Turns 1–4 to open a path, but non-essential peripheral foes should be ignored during the final Turn 7 assault on the main base objective.
