Games Like STARSHIP AVENGER Operation: Take Back Earth/スターシップアベンジャー 地球奪還大作戦

In a distant future... When mankind advanced to outer space,
the Crius suddenly appeared out of nowhere and began invading humanity.
Mankind's defense network in the solar system was no match for the overwhelming forces of Crius
and were quickly defeated...
However, mankind did not lose all hope.
The remaining survivors gathered to the Planet Kagutsuchi located close to the solar system.
They researched the Crius and mapped out the ultimate battle plan that would determine humanity's fate.

The essential factor to this plan is the newly built Space Battleship "Avenger."

Avenger’s mission is to intercept the enemies that roam in the solar system
and deliver mankind’s ultimate weapon "Thor's Hammer" back to Earth's orbit.

Thus, "Mission Take Back Earth," the plan to return to Earth
and retaliate against the Crius, is about to begin...

"Starship Avenger" is a defense shooter action game.

Blast off the weapons installed on Avenger to defeat the
enemies who come to destroy mankind's ultimate weapon!
