Just Yesterday I beat challenge 30 in the KoF 2002 UM The mission was to beat Igniz and Omega Rugal with infinite power bars with one character. My character of choice was Ralf.
Vs. Igniz- The best thing to do is move back, go RRRRRRRRRRRAAAAAAAHHHH , and punch him in his face repeatedly until he is dead. However sometimes I messed up and took some damage which sucks because they don't replenish your health between battles. Even worse is when I died to him because it was from a combo to Brutal God Project which does Major damage.
Vs. Omega Rugal- This guy has too much attack and defense. The best strategy is to go RRRRRRRAHHHHH and tackle him until he is dead. Also, you have to use supers against this guy, just don't mistime them otherwise you will eat a Gigantic pressure or a Genocide Cutter. If you have one bar, you can do 2141236+P to air 236+P for some good damage. If you have 2 bars go for 2363214+PP as it does great damage if you hit him. I barely beat him as one hit would have killed me and one tackle would have killed him. I go for the tackle , he tries to Repuken me but I go straight through it and hit him to win the match.
Mario Kart 8- I have all parts except for the Golden Glider. The Golden Glider requires 10000 coins to get :colonveeplusalpha:. You think that's enough Nintendo?
Zen Pinball 2- I have broken 100 million on Fear Itself. This is the 2nd table I broke 100 million on, the first one being paranormal. I will put my highscore here for all of the tables I own.
