It wouldn't be Halloween weekend if Telltale didn't offer a chapter of one of its adventure series for free -- well, we guess it still would be Halloween weekend, since ... that's how time
works. Regardless, you can grab Sam and Max: Night of the Raving Dead
this weekend for free.
To get the free chapter, just set up an account on Telltale's site
, and download the game to your account. Just do it before November 1, or else you're going to have to shell out a few bucks for it.
