Rockstar’s surprise foray on the Xbox 360, officially titled Rockstar Games Presents Table Tennis, is now available as a demo download from the Xbox Live Marketplace. For those of you that are on the fence as to whether Rockstar’s non-GTA product is worth your while, this should help you decide. As noted on Microsoft guru Major Nelson’s blog, the demo is available for download now but is a limited time trial. At the end of August, the title will expire - turning into a useless lump of 526 MB on your 360’s hard drive. If you’re hooked by then it’s time to shell out $39.99 for the full version.
