Two new game modes have been added to Undisputed 3 in the form of Stamina Simulation Mode and Competition Mode. Developers of the game have described how this will give gamers the option to play how they want to.
Stamina Simulation Mode is being described as a more realistic experience to a true UFC fight. Kicks and takedowns can't be thrown around constantly without using up a lot of stamina. Damage will also be increased so gamers will have to take their time and play more strategically.
Competition Mode is going the opposite direction by creating a "Street Fighter" or "Mortal Kombat" process to a match. Not much has been said about this mode but it may get rid of knockouts and stamina depletion to show who can win a time length fight.
