Dozens of real UFC fighters represent five different weight classes on the game's roster, and for the purposes of the game, each of them specializes in two fighting disciplines--one striking (boxing, kickboxing, or Muay Thai) and one grappling (Brazilian jiu-jitsu, judo, or wrestling). The intuitive controls, which map your fighter's limbs to the four face buttons, are largely the same regardless of which disciplines you're using, but the moves at your disposal are varied enough that every style feels different. Playing predominantly as a striker, you spend your time throwing punches and kicks, targeting your opponent's legs and body if you want to slow him down, or his head if you're looking for a knockout. As a grappler, on the other hand, your goal is to take your opponent to the floor, where you can indulge in some brutal ground-and-pound or use the right analog stick to transition between different mount positions in the hope of gaining an advantage. Forcing an opponent to tap out and submit is an especially satisfying way to earn a victory as a grappler, and the frantic button mashing (or analog stick rotating) that both fighters must engage in when a submission hold is initiated and the struggle ensues feels appropriate, if inelegant.
