Castle Panic is a new cooperative / competitive game from sggc Fireside Games scheduled for release in September.

It looks something like Desktop Tower Defense. Players win or lose together, but only the player with the most points at the end is the Master Defender or whatever. I’d tell you more about the rules, but the link to the rules is broken.

And the contents on the site are copyright 2010. Ah, no wonder the link is broken: the  site is from the future.

Update: link is fixed.
