http://www.gosunoob.com/far-cry-5/ve...dy-can-get-it/ media is even searching maybe its a bug?
People already came up with whats going on.
Basically youtubers and reviewers got *Press release* version of the game that launched with the version 1.1 and later updated to 1.2 (which is why some people got it in different regions). The patch opened up the weapon to the Press release copies but once the game went live it updated to 1.3 and removed the Vector from the list.
To get the Vector u will have to participate in the Events that they will organise every thuesday in April.
They already said the events would have exclusive rewards such as player skins and weapons.
So just wait for those events and i'm sure the Vector will pop up then.
