Ground and pound is broken, strikes are delayed. Clunky and unsatisfying in offense and defense.
The skill gap in striking has been reduced since ufc 3, extremely luck based as offense is only possible through guess-based counters.
Clinch system is unrealistic.
Knock outs look awful.
Graphics look the same as ufc 2 and 3.
Career mode is slightly improved but nobody plays this game for career mode.
