Have you purchased all five packs worth of downloadable content for Fallout 3 on the Xbox 360? If so, then this premium theme is yours free come October 1st.
Bethesda would like to send their fans a big thank you for sticking with them on the Xbox 360 Fallout 3 downloadable content front. Even after at least two of the five packs was released broken, you stood by the game, purchasing each new chunk of content as soon as it came out, from Operation Anchorage to Mothership Zeta. Your reward for such loyalty comes on October 1st, when the premium Fallout 3 Xbox 360 theme goes live. As long as you've purchased all five DLC packs by September 22nd, it won't cost you any bottle caps at all.
The rest of you can be prepared to pony up 240 Microsoft points. That's the price you pay - $3. Next time maybe you'll buy all the downloadable content, Dr. Cheapypants.
