People who got Xbox’s from the pilot program have you gotten them yet?

The DLCs are available online on the Microsoft Store on the Xbox One, so you should be good to buy them digitally and they should work. You don't need the disc version of those DLCs because the games are available on the Xbox One through the Xbox One's
Backwards Compatibility program, so the games and its DLCs are up for purchase. I think where you may have gotten confused about needing the discs is that often people who have the DLC discs from the GOTY versions of those games have had a lot of problems
getting them installed on the Xbox One. But, if you've got no disc, then you should have no problem.

Got a bad pilot? Easy pickings, got a good pilot, GOOD LUCK. Unless you have 2 people, one with a SOFLAM, one with Javelin.

Maybe look at the challenges you have to do to reach next gen

Example to reach level 6 next gen you need to kill 50 pilots who eject from there titan

easy not a chance i have played 18 hrs and am gen 2 level 30 and i have not yet had one pilot kill from titan

Most pilots are usually people from CoD who see Jets and attempt to fly them.. most give up after they can't get many kills, but some get better.

If you got contact information from the people running that promotion, you would need to contact them, but there was no such offer from Xbox or the rewards program at that time.
