With the arcade lineup having dismal as of late, the folks over at Microsoft Game Studios have announced a new set of Arcade games for the holidays. NinjaBee’s A World of Keflings will launch the program on December 22nd, and will be available for 800 MS Points. After that, Raskulls and ilomilo will be available in the following weeks.

In an interesting twist, it’s also been announced that all three games include unique content that unlocks if a player owns and earns an achievement in one of the other games. Additionally, A World of Keflings will kick off the promotion, and players who purchase the game will get early access (within the game) to buy the full versions of Raskulls and ilomilo before they officially launch.
