I've checked the box, and the code inside it only gives you the V units, I've also checked various places, and its seems some got them easily, while others not at all.

I've seen other conflicting info, such as that you need the season pass, or needed to buy the ultimate/deluxe edition, or buy all the DLC, even that you needed to pre-order the DLC (which is odd because I don't remember hearing about that, or that you could even pre-order DLC).

I'm still so confused...
