Wiped all my progress at 98.5% complete

Since I've completed this now and after reading all this my advice to new players is:
- Try to get everything bar maxing all suit upgrades and difficulty on your first run. Suit upgrades (and possibly weapon attachments?) are the only things safe from the save wipe
- You can safely break this playthrough up into several sessions. Reloading checkpoints is also fine.
- Do not spend suit upgrades points during missions 4-6 (inclusive). There's a bug carried from the original game where you may permanently lose those perk points and need to restart after deleting your save
- You can do recruit or jump straight into SS if you want. I personally did recruit first.
- After your first playthrough, do not close the game or try mission select, this is what causes the wipe.
- Instead, if you still need it, Start a "New game" on SS and run through it in one session. Don't worry, it's quite short and easy, maybe a couple of hours? This is also where you want to complete those suit upgrades. The only one I'll mention is Brute Force power kicks, you can get this out of the way during the first half of mission 2, when you're going through the inside of some rusty buildings. There's a couple of generators(?) you can kick in each enemy section.
- This is also where you can try again for any misc you might have missed the first time. For me, it was actually the story related achievement for completing Red Star Rising, which didn't pop during my first run.

- A final side note, I personally had an issue with the 10 turret kills and 25 supercharge kills getting stuck and 9 and 24 kills, respectively. After completing my second playthrough, I rebooted the game to confirm what I'd heard about the progress wiping. I then did a quick third run through to unlock those bugged achievements.


For anyone wanting a walkthrough, I found this really useful to avoid missing stuff on my recruit run https://youtu.be/BVieKyF0wA4

Great tips! This should be added to a walkthrough guide!

thatNoseyParker said:Gonna give this method a go, I'll report back in a week or so and let you guys know if this can be replicated.

Seems to be working fine so far. I've had one story related achievement not pop (Red Storm Rising) but everything else seems to be tracking fine. Still on my first playthrough though, we'll see how things end up.

Alright, just 100%'d the game.

Just to add to my post above....you don't need to delete your local or cloud save if you experience a wipe. I rushed through the campaign on Recruit after all my stats got wiped, got all the collectibles, achievement popped after I picked up the last one. Besides my screwup earlier, I can confirm that if you follow exactly what NoseyParker said to do, you won't have any issues.
