A portal appeared on the border of humanity, where purple spherical monsters began to appear. Now they are moving to conquer the capital. In the game Portal Defense you control the defense of the capital. Check everything carefully. Now use the special board to place crossbars at selected locations along the path and build scent towers. When the balls are within range, your turrets will open fire on them. With precise shots they destroy the enemy and give you points. In Portal Defense you can use it to build other defenses or improve existing ones.
