Ikaruga, which recently debuted on Xbox Live, shot to the top of the charts for the week of April 7. It also happens to be one of only two new entries in the Xbox Live Activity report. Almost everything else in the list just rearranged themselves from the previous week.

Ikaruga sits on first place in the top Xbox Live Arcade games and is in 7th place in the overall titles. Also making a reentry in the Top Arcade list is Chessmaster Live, which is currently in 6th place.

So which games were bumped out? Army of Two's demo is off the list, which is only expected since the full game is already out. Bumped off Arcade's list are Battlestar Gallactica and Assault Heroes.
