The graphics in K-1 are truly a mixed bag. Texture mapping is generously implemented onto the character models to good effect. Muscle cuts around the fighters abs, triceps and shoulders really stand out giving the champs that finely sculptured appearance. Facial features are also intricately designed with nose, eyes, mouth, beards and ears all prominently displayed. You can even make out the referees bowtie and buttons on his white shirt.
Great care seems to also have been taken with the special effects.
There is a lot of light-sourching and blending effects used when you connect with a punch or kick and also when you use your special attack. The light literally pops in and out in vibrant blues and reds as you pummel your helpless opponent. There is also a nice little light show at the beginning of each match with Roman candles shooting outing of the ring posts. The effect I enjoyed the most though was this really trippy blurring effect that takes place when you are moving your fighter forward or backward. Even the crowd is given a bit more detail then normal.
