It's Thursday, and we all know what that means. Meatloaf! But it also means that GameTap is offering another episode of American McGee's Grimm, which, as usual, is free for 24 hours. The new installment in the episodic, fairy tale-inspired adventure series is called Iron John, which is described thusly: "An iron-clad forest-dweller with strange powers by the name of Iron John takes a young boy under his wing, in exchange for the kind act of freeing him from imprisonment. With Iron John's help, the boy wins the heart of the princess and lives happily ever after - unless Grimm has anything to say about it." Other new additions for subscribers are Gothic 3 and Kingpin, while for us cheapskates, they are offering Metal Slug X for free for a week.
