Marble Blast Ultra (Xbox 360)

To do: Get screenshots. Need to see if using OpenMBU is an approved way to get screenshots as it is a port of the Marble Blast Ultra engine to PC.

This page details one or more prototype versions of Marble Blast Ultra (Xbox 360).

This prototype is documented on Hidden Palace.

A very early prototype of Marble Blast Ultra dated August 3, 2005 was dumped and released on May 4, 2026. It predates the final build by over five months.

General Differences#

• The main menu and level select is completely different.
• Many levels use placeholder textures, and the skybox is also completely different.
• The HUD is reused from the Xbox port of Marble Blast Gold.
• There is no music.

Title Screen#

Proto	Final

The title screen is very different and has no "Press A to start" or ESRB notice. The text is also glitched out, and the level in the background is different than the final (the final game uses Urban Jungle).
