Hey, this is for Kenny, so the rest of you all can safely ignore it.
FREE d20 MODERN ADVENTURES, SUITABLE FOR 4TH LEVEL PCs
-Trouble At Black Rock
http://www.wizards.com/default.asp?x=d20modern/oa/20030114a Summary: The modern industrial world is full of unexplained accidents involving machinery that seemingly went haywire for no reason. There is a reason, of course, but few modern people are willing to accept it. In most cases, modern people would rather have an unexplained mystery than a truth that conflicts with the safe, logical parameters of their world. After all, machines can't be alive, and they certainly can't be possessed. Or can they? Find out in Charles Ryan's new mini-adventure for the d20 Modern Roleplaying Game for 3rd to 5th level characters.
(NOTE: Charles Ryan did a lot of the stuff for the core d20 Modern book; he's a good designer.)
-Flames of Wrath
http://www.wizards.com/default.asp?x=d20modern/oa/20030408a Summary: There are those who hold that whatever evil you do eventually comes back to you, in either this life or the next. In this second adventure in the Team Bravo series, one of a psychopathic arsonist's past victims has come to exact vengeance. But the creature is fully as destructive as the criminal it seeks, if not more so. It's up to the heroes to stop them both before their flames can claim any more lives. Check out Eric Cagle's new miniadventure for the d20 Modern Roleplaying Game. This adventure is designed for 4th-level characters.
(Note: I think this has FX in it, but I'm not sure. I think it's still probably worthy of Shadow Chasers, though.)
