I created the following walkthrough for beating Mass Effect Andromeda on Insanity Difficulty. It includes full commentary that was recorded live, so I will be giving you my tips and tricks as we play along. I am playing this on a brand new save file, so this will NOT be on New Game Plus. The goal is to help everyone regardless of where they are starting, how many skill points they have, and what gear they have.
I start with the Infiltrator build so that you begin with Tactical Cloak, which is extremely useful. My build will basically be an Engineer with a few points into some combat skills. I will give advice on where to spend your skill points throughout, but basically, I will be using Incinerate, Overload, and Tactical Cloak the entire time as well as putting points into Combat Fitness and Assault Rifles. Any extra points you have are gravy and can be used to upgrade things like Barriers and Tech Powers.
I will be going through this with almost bare minimum skills, so anyone watching will likely be a higher level than me. I will only be showing the main missions and a few of the Loyalty missions (Vetra's, Cora's, and Peebee's, done only to upgrade skills if you aren't doing this on NG+).
The rest of the videos will be under a spoiler tag.
