If you already own Remedy's previous game Alan Wake, but have never gotten around to getting the game's two DLC expansion packs, you don't have an excuse anymore. Both The Signal and The Writer are now free to download for Xbox 360 and Xbox One owners.
Alan Wake, along with the expansion packs, were recently made available to play on the Xbox One via backwards compatibility. Also, people who pre-ordered Remedy's new Xbox One game Quantum Break got Alan Wake and DLC packs for free. Alan Wake itself is still priced at $19.99 in the Xbox Store.
