Two new games were added to the Xbox Live Arcade today. Orc Attack: Flatulent Rebellion ($9.99) is a third-person hack and slash that involves orcs and more than a little farting. Meanwhile, Let’s Sing and Dance ($9.99) is a Kinect-powered music game that features… wait for it… singing and dancing.

More details on both games can be found right here:

Orc Attack: Flatulent Rebellion
Fart or die in this hack-and-slash action game, where fun-loving Orcs battle pollution loving Humans in a humorous fantasy setting. Orcs have become victims of brutal Human expansion, as they are carelessly poisoning the environment. Now, four trained Orc heroes are retaliating with a Not-So-Silent yet very deadly plan. In either single-player or up to four-player co-op, you will take on the role of Orcs, each wielding a unique gaseous ability, and then take the fight to the Humans in a stinky, fart-filled romp. Hilarious enemies and highly tuned combat make for a joyous experience that really is worth sharing. While the comedic storyline and the striking 3D world make it even more memoragle. Gross but charming protagonists add the final flourish with flatullent group attacks and nasty killer moves for up to four players.

Let’s Sing and Dance
Let’s Sing and Dance for Xbox 360 (Kinect for Xbox 360 compatible) brings music games to the next level. For the first time ever, a game combines singing and dancing at the same time. Using Kinect for Xbox 360, Let’s Sing and Dance scores the players’ dance moves as well as their singing performances. Unlimited number of players can take the stage at the same time and chose between 12 hits from major artists, including Lady Gaga, LMFAO, Flo Rida, Bruno Mars, Miley Cyrus, Maroon 5.
