Biggest concern is. How much sci fi.
And if we finally will get a spear gun
I'm ok with sci fi, but the internal consistency is important for me. Spear guns are cool, I'm in.
EDIT: If we get a spear gun, I want a full James Bond Thunderball getup and the underwater vehicle from the movie as a scorestreak. If there is to be fan service, I want my fair share.
And no cosmetic bs.
The unfortunate part is that the bs hidden behind rng encouraging players to buy CoD points won't be cosmetic only.
