Hey Edgar! Quick question, if I enable cross-save for my titan who I have on PS4, Will i be able to play on both pc and PS4 with that character whenever I want?
Or is it like I move my titan over to pc and have to move it back to PS4 when I want to play there?
Yes - so basically what you're doing is selecting a set of characters that will be the ones you use on all platforms. It's a semi-permanent choice: you can undo it, but you must wait 90 days before you can choose a different one if you undo it.
Once you choose those characters, they are the only ones you can play on any of your linked platforms. So if you have a Titan on PS4 that you want to play, you'll need to choose your PS4 set of characters: at that point, you can play those specific characters on PS4 and PC at will with no further ado!
