Welcome to the second episode of Extinction, Mayday. In case you've been following the story, this takes place 26 days after Nightfall, and still focuses on the mad scientist, Dr. Samantha Cross, and her attempts to presumably master control of the aliens.
When you start off, it will be like any other Extinction game. However, crafting has been brought back from Black Ops. You can grab these schematics and search around for any parts you need. There will also be safe rooms containing certain parts that will require the drill to laser through it. When you reach the next area after destroying the doors and barrier hives, you will fight and kill a tentacle. When you drill your way further, you will kill a Phantom and a Rhino.
You will then encounter a large, open cargo area. Make sure to drill through the first down downstairs doors; there will be schematics for a custom Venom-X. After you make your way to the top deck, charge forward to the larger interior of the ship. This will be a rather challenging area; there are a few pipes containing fear gas. You will need to maintain these and be sure that they do not get destroyed; if they do, the game is automatically failed. After that whole fiasco, you will finally reach the very top deck, and this is where the Kraken will spawn.
This boss is significantly more difficult than the Breeder, mainly due to the fact that he is not only enormous, but the area will be littered with endless aliens, so watch your back. He is not as repetitive as the Breeder, and actually sits still, making the actual strategy for fighting him easy. I highly recommend that you do this with three co-op partners.
- Medic: Fully upgraded Medic skill tree; also have him apply Team Boosters
- Tank: Fully upgraded health; Death Machine; full armor
- Engineer: Upgrade to max wallet to fund traps and sentries
- Weapon Specialist: Use explosive ammo; fully upgraded MK32
You can use any weapon for this, but I highly recommend the upgraded MP-433 Grach for this, and as a primary weapon, the new Ripper submachine gun/assault rifle, which can be very powerful if used correctly.
Now onto the Kraken. His health bar will be just as high as the Breeder, but this should not concern you. Just like in the first battle with the tentacle, he can deploy Cryptids from his own arms. During the fight, there will be Hunters, Seekers, Scouts, and Phantoms. It will be best to have the specialist drop explosive ammo and rain fire with a turret, the medic deploy full armor and boosters, the tank draw fire and divert enemies for quick healing, and the engineer provide most of the support expenses.
After you bring his health bar extremely low, he will violently thrash around. When you finally kill him and he drops dead, the game will end. Achievement unlocked!
