XboxExclusive.com writes: We recently had the opportunity to work with the development team for Fight Night on an exclusive interview, and we are glad to share this with you.
These were answered by Jeff Atienza, the lead producer on Fight Night Champion.
From the interview:
"We have even added fatigued punches for when your boxers stamina is drained in the late rounds. Also new this year is the elimination of the haymaker punch. We don't have any over-the-top punch animations that no boxer in real life would throw."
