Finished the game 100%. All achievements & everything unlocked. Played all on Series X. Took 3 weeks. Last half I got to use my new Turtle Beach Stealth 600 headset with it. Amazing experience. Definitely want a sequel.
And yes, you can get all achievements except last 2.One will unlock immediately afterward completing story. Another one will unlock if you scanned all enemies except the last one. If you don't unlock all enemies or any of the other achievement before finishing story you can go back & visit all the previous planets to finish them. I didn't need to go back since I finished them all before finishing last planet.
