CoD BO7 has added a brand new aspect to its campaign in the form of the Avalon endgame mode, which has its own progression, activities, as well as a final boss.

But, getting to that final boss is easier said than done, as it is located within the challenging Tier IV area of Avalon, and requires a lot of grinding to defeat it.

Here is what you need to do and how you can take on Dr Falkner.

How to Reach CoD BO7 Endgame's final boss

COD BO7 Season 1: Several characters can be seen on a multiplayer map. Some running and one planting a bomb.

Choose an Operator and complete objectives and secure Comms Towers to level up your combat rating.
Level up your combat rating to at least Level 45 (ideally Level 50-60)
Travel to the Toxin Source Island in Zone IV
Shoot all the Red Flower Spores on the walls and environment on the island until the boss spawns (you need to shoot quite a lot)
Defeat Dr. Falkner

This boss fight isn't anything special, with it simply being a bullet sponge until you defeat it fully. But, it is quite challenging and a long fight, so if you can bring some team mates to help you then it is worth playing co-op to take on Dr Falkner.

Once defeated, you can obtain a Exotic Ghostmind sniper rifle weapon blueprint, as well as a unique skin for the operator you used. You can confirm your kill of Dr Falkner, to exfil from Avalon and see a unique cutscene, tagging onto the end of the campaign.
