The Last Turret

The Last Turret is a casual shooter in which you play with one hand as an ancient turret defending the Etherians from invaders. After millennia of peace and prosperity, invaders appear in the northern sky, and the turret—an ancient relic of the Etherians’ long-ago wars—becomes their only line of defense.

You upgrade your weapons and defend cities, then watch over convoys as the Etherians flee falling cities. Finally, you attack the mothership and drive the invaders back into the sky.
