https://imgur.com/a/g36zarA I finally S-ranked all levels. Tattoos are proof of completion since they are only obtained when you S rank a level. And for each level there is one tattoo, obtainable only when you S rank said level. As you can see, there are 18 of them. For some reason, only levels completed while solo count towards the Steam achievement. However, since even the game itself recognises that I S-ranked the level legitimately, this achievement should actually be granted to me even if it doesn't show on Steam. And I actually managed to solo S-rank some of the hardest levels in the game. Specifically, Relapse and Greased Palms. I had a bit of help through Commander mode where I have access to officer traits, but this still isn't a complete replacement for a competent human player who knows how to use his grenades. For the S-rank, the main tip I can give you is to take it slow. Pack more grenades, since you will rely on them when under heavy fire.
