Mayfair Games publishes Chill and used to publish DC Heroes, but that has gone out of print. You can still find copies at Darkside Gaming, a purveyor of out-of-print gaming books.

Chill is a horror-genre RPG.

DC Heroes is a superhero RPG set in the world of DC Comics.

The author of this page has played neither Chill nor DC Heroes extensively, but her husband has played both, so she will hit him up for a review in his copious free time... :-)
