2K has revealed Season Pass model and pricing: https://nba.2k.com/2k24/season-pass/
2K24 is joining the likes of other games with Season/Battle/Whatever Pass models.
There will be three tiers: Free, Pro and Hall of Fame.
Free option will work as it works in 2K23. 40 levels in MC and 40 levels in MT. You can earn all these by playing the game.
Pro pass, at 10 dollars, gives you extra 40 rewards to earn by playing the game and 4 additional rewards that are separate from the other rewards and are unlocked immediately on purchase.
HoF pass, at 20 dollars, gives you what Pro pass does, then 1 extra additional reward, 15 % XP boost for the duration of the season and 10 level skips.
Additionally you'll be able to purchase a 10 dollar pass upgrade which will upgrade Pro pass into HoF pass and level skips, which will be 2 dollars per pop.
Each season will be 6 weeks long.
Season passes will be available on all platforms including old gen.
You can purchase the pass after leveling up and you'll get what you would've earned.
XP boost starts applying after HoF pass purchase, doesn't act retroactively.
