A new video for Fight Night Round 4 is available for your viewing pleasure. In it, producer Brian Hayes talks about what changes players can expect from Round 3 to Round 4 with respect to the game's physics. He explains that in the first game, there was an invisible wall keeping the two boxers separated, which is not the case in Round 4. The next installment will feature improved collision detection and less clipping, which is something Hayes hopes allows for more realistic punching people in the face and/or body.
If you're not content with the video, punch your way into our gallery below, which is full of new screens.
