Metal Melon is an upgraded melon plant encased in a metallic shell that dramatically increases both its projectile impact and its own durability. Its metallic melons deal heavy damage on impact and can pierce through standard zombie armor, making it especially effective against shielded or armored enemy types.
The metal casing also gives Metal Melon a secondary attribute — its projectiles cause knockback, staggering zombies on hit and pushing them back slightly toward the edge of the lane. This delay effect is subtle but meaningful during large waves, buying other plants additional time to fire.
Metal Melon is an Upgraded variant that benefits from the base Melon-pult skill tree, meaning plants in its fusion chain can be further enhanced with upgrade tokens. Its combination of armor penetration and knockback makes it one of the stronger single-target melon options available in its tier.
