While the Games for the Holidays promotion certainly showcases a variety of Arcade titles, one of the more impressive features was the cross-game integration. Due to demand, Microsoft has releases a trailer showcasing that very functionality. By purchasing any of the three games, exclusive content will be unlocked in one of the other titles. Best of all, all three titles will support exclusive content for each of the other titles.

While features like this have been seen before, it’s interesting to see developers working together with Microsoft on such a collective effort.
