Cosmonauts (コスモノーツ Kosumonōtsu) are a new enemy type introduced in Earth Defense Force 5, and like the Colonists fill the role of the Hectors from Earth Defense Force 2017 and 2025. They are encountered later in the game, and are among the most challenging enemies in the game.
The Cosmonauts are a powerful enemy type that resemble very tall stereotypical "grey" aliens. They are the second wave of human-like soldiers deployed by the Primers in their invasion of Earth, the first being the frog-like Colonists. Like the Colonists, Cosmonauts are typically deployed into battle by Landing Ships. It is likely that the Cosmonauts are members of the very alien race behind the Primer invasion of Earth. Cosmonauts wear armored spacesuits that give them the appearance of a robot upon first glance, however their spacesuits can be damaged and destroyed by gunfire. It is necessary to destroy the Cosmonauts' spacesuits in order to damage and kill them. Like Colonists, Cosmonauts' limbs can be severed once they are exposed, leaving them crawling on the ground or unable to fire their weapons. However, if they are left alone for enough time, Colonists will regenerate severed limbs. Cosmonauts are highly intelligent and will communicate and coordinate with other Cosmonauts and Colonists, making them very challenging in groups.
There are five variants of the Cosmonauts:
The most common variant of the Cosmonaut is Infantry. Infantry carry the Cosmonauts' standard armament, a gun known as the Ether Rifle. This rifle is smaller and deadlier than the Ether Gun carried by the Colonist Infantry.
Cosmonaut Attack Soldiers are equipped with a powerful shotgun called a Rapture Gun, the same type of gun wielded by the corresponding Colonist variant. However, the Cosmonauts' Rapture Gun is both smaller and deadlier than the Colonists' and fires a damaging spread of light bullets.
Snipers are equipped with a high-powered long-range laser cannon known as the Raster Cannon. The Raster Cannon is said to be the deadliest of all weapons wielded by the Cosmonauts. It possesses a range ten times greater than the Ether Rifle, and is extremely accurate at long distance. The Raster Cannon possesses tremendous destructive power, and can wipe out entire EDF units in a single shot.
Heavy Armor SoldiersEdit
Heavy Armor Soldiers are equipped with an additional heavier layer of armor on top of their spacesuits, making them extremely difficult to damage or kill. However, their heavier armor makes them able to move only about half as quickly as other Cosmonauts. When their extra armor layer is destroyed, they will begin to move as quickly as normal Cosmonauts. Heavy Armor Soldiers wield Heavy Ether Guns, more powerful versions of the Ether Rifle that function like Gatling guns. They possess higher rates of fire and greater damage output than normal Ether Rifles.
Heavy Explosive SoldiersEdit
Heavy Explosive Soldiers wear the same armor as Heavy Armor Soldiers, but wield a powerful explosive launcher known as the Wrecking Launcher. The Wrecking Launcher fires explosive warheads from a port on the tip of the launcher that opens and closes. They are considered to be one of the most powerful Cosmonaut variants.
