GOG is holding a Halloween-themed sale this weekend with some great deals on new and classic horror games.

For example, you can get Outlast for $5 and its Whistleblower DLC for $3. It's a good chance to pick up the games and catch up before the release of the sequel, which the developer confirmed is in development earlier this month.
