The PSP release of Housemarque's omni-directional shooter Super Stardust is missin game modes that are promised on the game's purchase page, IGN reports.

The game--only sold as a $9.99 digital download via the online PlayStation Store--is said to contain "plenty of modes to satisfy your trigger finger needs, including Arcade Mode, Planet Mode, Endless Mode, Bomber Mode and more."

While the listing makes it sound like the game contains all of those modes, it turns out that Endless and Bomber Modes are missing from the final product. An in-game statistics page also mentions a Survival Mode that is not present.

Those modes will return, says IGN, in a forthcoming expansion pack that "you'll have to pay extra for it." No release date or price has been provided for the expansion.

This week's PlayStation Store update brings about a free issue of Sony's online video magazine Qore, normally priced at $2.99, along with downloadable content for a number of PlayStation 3 games and some PSP versions of popular PS3 games.

If you paid $24.99 for an annual subscription to Qore, don't worry. Since the magazine is free this month, annual subscribers will find an exclusive demo for Proper Games' upcoming animal-kidnapping game Flock in their Download Center.
