From what I was reading from IGN today, it appears that when 343 said the battle pass was a one time purchase, they meant per season.
Has anyone come across any new info on if the purchase is across the entire life on Infinite, and re-ups every season, or do we purchase each season individually?
You will have to purchase the new Battle Pass each season. The good news is though that each season will be available indefinitely and you’ll be able to go back and complete them at anytime should you miss one. The Season Pass shouldn’t be too expensive, maybe $10 - $15.
Absolutely no fear of missing out either, it’s great.
Each season battle pass once purchased will never go away. You can work towards grinding out the specifics of each one at your own pace. Pretty solid if you ask me.
