FAT Princess

FAT Princess is a PSN-only game that was revealed at E3 this year. Essentially a 2D (great), cartoony (even more great), TF2-like (GASP!) capture the flag game, but the flag being the titular FAT Princess.

32 players battle it against each other to barge to the enemies castle and take the princess back to theirs. When players spawn they can wear hats (aka select a class) and go out and do damage. There are 5 classes, one of which is a Priest, akin to TF2's Medic.

The clever bit is, the FAT Princess needs feeding. Stop feeding her and she gets thin, light-weight, and hence a lot easier to carry. A team that just goes out fighting will leave her to starve, and hence when the other team reach their castle they'll find that carrying the Princess back is a lot easier :)

BUT, focus on feeding the Princess (albeit with magical vanilla cake that grows outside :p) and she'll get FAT, and heavy, and difficult to carry. A very clever twist to the age-old CTF formula, and one I think not only will be a success but also be copied in more traditional FPS titles.

The game is meant to debut later this year on PSN. PS3 Fanboy have more on the title here.
