-Story
In a parallel world where the Earth is made of blocks, evil has befallen the otherwise peaceful planet.

Led by Dark Tyrant, several Motherships suddenly attacked the planet, shattering the Earth into pieces.

The Earth has been attacked by the Invaders, Ravagers, and Aggressors before...but the brave EDF soldiers have always joined together to defend the planet from these threats.

With the Earth shattered, EDF soldiers continue fighting on each of their pieces of the planet. But with no way to reach each other to deliver aid or food supplies, the planet remains in despair.

You must assume the role of Commander of the EDF and fight back. Find the EDF soldiers fighting around the planet, and begin a counteroffensive. Only a powerful team assembled by you can save our square Earth.
