The season includes new challenges, player items, and events in the game's Ultimate Team mode, with special items and programs running through the season.

If the inquiry was about the start of the actual 2025 college football season, it began with a "Week Zero" on August 23, 2025, with most Division I programs starting their seasons the week after. The main 2025 college football season Week 1 began around August 28-30, 2025.
