I imagine it would be the same situation as it was with Free Fall for Ghosts. Nuketown2025 was a pre-order bonus that was then released on all platforms (bar Wii U) for all players for free.
So, it's 99.999% certain that we've got it to keep now. It would also be highly unethical and really bad practice if they force it into peoples hands via a required update only to request payment later.
I love Nuketown, but NT2025? Its....alright haha But Im sure all U owners can say that the release is really appreciated.
I flew past the message of the day. Is Nuketown for keeps? If it is, why did we have to download Freefall and not this?
Thanks for the new map!
