Kung fu 3.0 is a hand-to-hand and combo move system, with advanced shootdodges and acrobatic skills. It includes: An arsenal of over 20 different moves in a Kung Fu Skill Level system, a complex combo attack system, Improved acrobatic skills, the "drunken style" shootdodge and the aerial shootdodge. Improved impact physics that allows for juggling bodies and "slamming" bodies into walls and other enemies and "The Dojo" training area that teaches you the basics of the kung fu fighting system.
The mod itself is absolutely fantastic. However, when you unlock a new skill you have NO CLUE how to use it. Things like "Wall Run" are extremely obvious, of course, but some are much more vague and I went most of the game not using almost all of the skills I unlocked.
