Vigilante Arcade Remake
Given the fact that I love the recent unofficial Kung Fu sequel adding this particular remake was a no brainer. This game was released in 1988 and is sort of a spiritual sequel to the original Kung Fu Masters arcade game (simply called Kung Fu on the NES) with better graphics, better sound and faster gameplay. And this remake manages to keep all that while fixing a few of the bugs, keeping some in because a lot of the time bugs in these old games are interesting and adding weapons (the original only had one).
Kung Fu 2 - Unofficial sequel to the classic NES game.
Ah the days of old playing the original Kung Fu on the NES. My 7 year old brain couldn't comprehend the sheer awesomeness of that game. And even today I can still play it and like it, but it hasn't aged well. It came out in 1984 by Irem which featured the typical side scrolling fighting of the day where you kicked and punched your way through the dojo levels to save Silvia from Mr. X fighting goons, knife throwers and at the end of each level a boss. Fast forward to 2008, and someone made a 6 level sequel to the game for PC and won the 2008 Retro Remakes Competition for Games Without Sequels category simply named Kung Fu 2. Hit the jump for screenshots, a little bit more from me and the download.
