Microsoft have announced a new Xbox Live Arcade called Game Feast kicks off on September 29 with Hydrophobia (1200 points), continues with Twisted Pixel's Comic Jumper (Oct 6, 1200 points), and Pinball FX 2 (Oct 13, you pay for each table), and ends with Super Meat Boy on October 20 (no price announced).
This year's summer of Arcade was pretty sweet with stellar titles like Lara Croft and the Guardian of Light, Limbo and Monday Night Combat, so hopefully we'll get the same level of quality with the next campaign.
Microsoft also revealed the line up of XBLA titles leading up to Game Feast with Plants vs. Zombies (1200 points) and Dance! It's your Stage (800 points) on September 8, and Dreamcast re-release Sonic Adventure (800 points) on September 15.
