Alien Line Defense / H5

Alien Line Defense H5 Play

Slide the cannon left and right to line up a column, fire straight up, and wipe out the descending formation.

The formation steps on a fixed cadence, dropping a row and reversing when it hits a wall. Shoot it down before it reaches the cannon row. Destructible shields soak shots. You can also use the arrow keys (left / right) and Space / F.
