That and getting to Wave 100 on Joust/Robotron are
impossible because the highest level you can get to basically is Wave 99, after that the game would reset (unless they updated it).
As for the hardest Achievement, I'm going with beating Lost Planet on Extreme and finding every target marker on it. And 7-Day Survivor on Dead Rising (unless your obsessed).
