Most companies today will gladly charge you for DLC and nickel and dime you to death. Yacht Club Games has a different approach, with releasing the Plague of Shadows DLC for free starting tomorrow. Plague Knight must traverse the kingdom, hunting down old foes who hold ingredients to making the Ultimate Potion. The only catch? You have to own the original Shovel Knight and complete the game before playing. The mechanics for the expansion look really well done, and it adds a crafting system to the game as well. Also promised are new enemies, remixed stages, and more! You can check out the full press release on the Yacht Club Games website.
