Oh, here’s a good one to bring back some fond memories. Remember the old Irem game for NES called Kung Fu? Yes, you remember the burlap sack sound effects, stiff controls and endless barrage of foes you couldn’t wait to take down. Well, Gary Gasko has gone and created an unofficial sequel with better visuals, better sounds, and better control. Cleverly titled Kung Fu 2, this nostalgia trip features nine stages and a surprisingly accurate reproduction of the original game’s mechanics. You know, only… better.
