Like its predecessor, UFC 4 continues the use of EA Sports' Real Player Motion (RPM) technology. For clinches in particular, EA says it will use RPM to make clinches look and perform more believably by taking into account player positioning and physical context.
The game will also crank up the realism to emphasize the impact of attacking moves. For example, EA says players will "see, hear, and feel the disorienting impact" of the fights. This will include a new presentation system that gives you replays of devastating punches and more.
