Hammergrub

Description
Massive, slow, armored creature that focuses solely on breaching structures with its mighty tongue. Units in its path will be ignored and trampled, like a bug.

Hammergrubs are large, insectlike Fell. They are some of the first enemies in the game to have high armor. They will ignore troops but attack towers.

However, any units standing in a Hammergrub's path will be damaged over time, so it is best to steer them clear of a Hammergrub's path.

Strategies

 * Snipers with the tech "APD5 Bullets" can deal massive damage to these enemies, as their high armor will be ignored.
 * Additionally, Snipers with the "Lethal Weapons" tech have a chance to instant kill these behemoths. Combined with "APD5 Bullets" they can cripple these creatures if they are not instant killed.
 * Flamewalkers are a viable choice, as their attacks ignore armor. However, their DPS is not great, so they are generally outperformed by other units.
 * Guardians are good options (Available on levels after Search and Rescue) as their psychic blades will melt through half of enemy armor. This innate trait, combined with their fast attack speed, gives them a great advantage against Hammergrubs.
 * Diplomats with the "Tulpa Sentry" tech can distract Hammergrubs, as Tulpa Sentries are classified as structures and Hammergrubs only target structures.
