Are the servers shut down on Playstation? (i’m assuming since you said Platinum your on PS). I don’t know 100% of all the achievements on there, but as long as none of them depend solely on another player being there you should be able too run Multiplayer missions Solo, i used to do it for years on my first few playthroughs when i was younger. But yeah, i get your frustration. There’s so many games in my collection i just can’t 100% because of online, whether it’s servers shutting down or just general multiplayer troubles.

How’s Odyssey btw? I’m embarrassed to admit that Odyssey i initially skipped over because i didn’t think i’d like the way the story was going being pre-assassin’s and the gameplay, but i picked up Valhalla later and loved the gameplay bit (at least in small pieces) so i’m wanting to give it a try since i got it with the entire AC bundle on Steam.
