Digiex member @Gunz4Hire has released a new homebrew game for the Xbox 360, PADDLE MEYHEM.
PADDLE MEYHEM is essentially Pong meets Geometry Wars and really does take you back to the early days of XBLA when the 360 launched in 2005, with a great soundtrack to compliment the game too! If this was on XBLA I'd have purchased it for 400ms points back in the day.
If you have a Jtag / RGH hacked Xbox 360 this is well worth checking out, you'll certainly get a bit of nostalgia playing PADDLE MEYHEM. You can download PADDLE MEYHEM from the release thread over in the Digiex Download Center.
Its great to see homebrew activity taking place on the Xbox 360 12 years after we got the Jtag hack, allowing the average person to run unsigned code on the 360.
