DreadBall combines various sports and mashes them together on your tabletop... which invariably has your players mashing into one-another on the tabletop as well. It's a good time had by all (if you enjoy mashing, that is). Xtreme takes DreadBall to the streets. It's wild. It's crazy. It's without rules... well... kinda. I mean, there's the rulebook for the game. And if you buy XTreme this month, you'll get an extra rulebook in the form of the first expansion for free from Mantic.
It's pretty simple. Just get the DreadBall Xtreme box set during June and they'll give you the DreadBall Xtreme Player Manual for free. Free books! Everyone loves free books.
