Correct. You need to be on latest to go online but you can still edit it into your inventory and use the Equip menu and Shooting Range offline, and it's probably possible to swap out weapons in Octo Valley too but I haven't gotten that far yet.Thank you for teach me. I maybe understand.
In other words you can unlock any weapon on the list,but at this time you can't unlock any weapon of the future coming.
I had been thought you are only can connection.
