The Kraken Experimental Giant Submarine is a Cybran major experimental naval unit, having the appearance of a large squid. It is equipped with 8 tentacles which fire laser beams that are effective at targeting naval, land, or air units. It is also equipped with 3 torpedo tubes which it uses to engage other submerged units. Because it is submersible, it can easily escape from an unbalanced enemy force.
Use the fact that the ACU builds twice as fast to your advantage, allowing you to make these powerful units in 1:35 rather than 3:10, quicker than any assisted gantry. Do be careful about the frankly obscene amount of resources this will consume however.
You can submerge the Kraken, which makes it vulnerable only to torpedo weaponry. In exchange, it cannot use its tentacle weaponry.
The Kraken has the notable ability of being quite effective at destroying air units.
It is ineffective against the IIluminate when submerged due to torpedos having no effects on hovering tanks and units. Conversely the only unit the Illuminate has to target submerged units is the Wilfindja, (and Yenzoo tank with DLC and research) if the Illuminate player possesses one, It is a waste of resources to construct a Kraken as the Wilfindja will be an even fight for it for approximately half the resources and less than half the build time.
The Kraken is one of the 3 units that can submerge in the game - the other two being the UEF Tigershark and Atlantis II.
Though armed with torpedos do not leave the Kraken unguarded because it is EASILY overwhelmed by a few submarines. (If the Kraken is up against 10 to 12 Tigersharks it will lose very quickly and most likely won't even kill one of the submarines)
The Kraken is somewhat useless in groups if attacking targets on land as usually only one will be able to attack and short range artillery or land units can easily deal with it. The Kraken is better off being used as a base defense for incoming naval or air units that try to go around your base.
If it's struggling to destroy a ship, just let it come up and use the laser tentacle.
There's a glitch that if you are attacking another unit and submerge then the beam attack will still be going even while moving and swimming. This can be fixed by having it submerge and attack another unit and kill it.
