The Kraken is an ultimate weapon brought by the Future Rebels to help launch another Morden coup d'état. It is equipped with with super thick photon armor which even protects it from lava as well as various weaponry from the future, such as cylinder grenades, and an ultra huge cannon. It is also equipped with armed tentacles for recharging its energy with lava.
The Kraken is found in the final mission first exiting the Big Gate to save Morden. It is then seen residing near the edge of the volcano with various tentacles connected to it. The player stands on scrap material floating on lava inside the volcanic crater. The boss fight comes in two phases.
Phase one is fighting each tentacle one by one. The tentacles emerge from the lava and attempt to smash the player or rotate its segments to destroy the scrap metal. It can also fire electric balls or toss chunks of magma.
Once every tentacle is destroyed, the Kraken floats to the battle arena where phase two begins. The Kraken can:
- Dive under the lava, creating waves of lava in the process, and produce sensor mines to destroy the scrap metal. Then it will submerge directly beneath the player and destroy the scrap metal it smashed through.
- Fire an enormous cannon shell, that can bounce off the scrap metal, from its giant cannon.
- Drop magma boulders from its very bottom.
- Drop cylinder grenades that bounce once before exploding.
- Summon small projectiles called Satellite Ammo in a circle and toss them individually.
Pods occasionally linger around the arena backing up the Kraken; grenades and weapons appear after destroying them.
It is noted that the timer does not reset between phases.
The Kraken starts to sink into the lava once destroyed. The ending credits show the main cast, Morden, and a few Rebel soldiers huddling on top of the sinking Kraken before Rumi arrives to the rescue inside of the Regular Army Helicopter.
In Other Games
