About This Game

Start small. Build toward a decisive strike.

The enemy is advancing. One base remains—and you are its last line of defense.

SENTAI MECHA: LAST LINE is a single-player incremental defense game built around growing firepower, heroic transformations, and giant mecha combinations. Earn resources in battle, choose upgrades, and unlock new ways to fight. When your advance stalls, regroup and return stronger.

From frontline fighter to Guardian pilot

Begin as a frontline fighter, unlock the Red Suit, and summon the mighty Guardian. Your unit fights automatically while you intervene with base support fire and active skills. Automate your support fire as you progress.

New forms. Different ways to fight.

Use Volt's protective barrier and heavy impacts, Ray's afterimage double strikes, and Nova's multi-target attacks and lightning firepower. Each ally-linked form brings its own skills and battlefield role. Unite your strength in combined forms and unleash powerful finishers.

Choose your next breakthrough

Develop your offense, support, and defenses through the skill tree and research lab. If an enemy stops your advance, regroup, adjust your upgrade priorities, and try again. Your investments and unlocks shape the next battle.

Anime-inspired mecha spectacle

Experience Guardian deployment, ally encounters, new forms, and decisive attacks through in-game cinematics. Build up power, release your finisher, and defend the last line.
