The Ketea is an assault submarine. They are equipped with a powerful torpedo launcher that can deal lethal damage to structures and ships within seconds. However, they are also very vulnerable due to having low health. They are invisible to radar and to units on the surface, but are visible to sonar and other submarines.

If your enemy is not careful, you can sneak one or two of those into their base and wreak havoc.

Their main use is destroying underwater metal extractors, and trapping fleets which don’t include proper anti-submarine units, like destroyers.

Their torpedoes are not guided, and can be dodged by keeping mobile.
