    I just finished the Infinite Warfare campaign on Veteran difficulty and I have to say that it isn't that hard.
    I can't put down a whole guide, because you probably don't need it.
    However, I can provide you guys with a few tips:

    - Probably the most important tip, stay.... behind... cover! I am a very fast person and I like to rush things, trust me, you can not do that in this game. Take your time and take out all the enemies in each section one by one. They don't spawn infinitely. I used the NV4 Assault Rifle throughout the entire game. Equip the attachments that you prefer (I do advise equipping Extended Mags) and I liked the ELO sight. For your secondary weapon, take an energy weapon to take out robots with ease. I used the VOLK Assault Rifle.
    In terms of equipment, Drones, the Portable Shield, Seeker Grenades and Shock Grenades are your best friends. Spam these as much as you can, because they WILL help you a lot. There are numerous places in the game where you can restock your equipment.

    - When you do the Jackal missions, make sure your Jackal has the extra armor equipped. You will die pretty fast in your Jackal so use Flares frequently and always move (if you hover for to long, enemies will do the same and surround you and you will be dead within the blink of an eye.
    Use resupply drones to replenish your rockets, they are very effective against enemy attack carriers.



    Again, take things slow and enjoy the campaign and it's setting. Note, in order to get this achievement, you need to complete all of the 31 missions (main missions + side missions).

    Enjoy the game, if you have any questions, suggestions or other feedback please write that down below! Good Luck smile

    By the way if people are still trying to get the Personal Decorator achievement in Black Ops 3, I have a guide for that as well.

    LordSmorcWhat Devious Jedi said has worked for me for several campaign achievements.

    - press Xbox button to bring up the menu
    - go right 3 times so you're on "Game activity" section
    - Go to official club
    - navigate through the different tabs using lb/rb, my achievements so far have unlocked instantly upon going to the "Progress" tab

    I strongly recommend that you finish the side missions & a Recruit playthrough before attempting this.

    The video linked is for the best possible loadouts in the game both for guns & your Jackal jet.

    When fighting the C12 robots feel free to pickup rockets in place of your secondary gun

    For the most part the hardest areas in the game are going to be fighting the C12s & while you're in zero gravity. If you're in zero gravity feel free to use your grappling hook to either camp behind any cover or rush ahead for a checkpoint.

    Note that you have to finish both the main story & side missions.
