Reality Storm is a book for both Champions and Silver Age Sentinels, where Kreuzritter, the ultimate bad guy of the Silver Age Sentinels Universe (Referred to as Empire-Earth) and Dr. Destroyer, the big bad of the Champions Universe (Reffered to as Millenium-Earth) team up to take over the worlds. And it is up to your characters to stop them!

The adventure is statted out in both the Hero System and the Tri Stat system (Sorry, SAS D20 fans), and it's an epic of an adventure. Cameo appearances from characters from both worlds were a cool addition to the adventure.

The adventure takes up most of the short, 96 pages in the book, but the main event for me is the conversion matrix between the 2 systems. The rules are very detailed and are pretty accurate, and for the most part provide loyal translations from one system to another. However, the conversion matrix can a little off at times (converting from HERO STR to SAS Superstrength levels, Determining Combat Values), but it allows for use of each companies characters to fans of the other company.

Overall, a good book, and worth the 20 bucks.
