The Humble Bundle's partnership with WB must've been a pretty big success, because they've just added a whopping three more games, and three more DLC packs.
The bundle was created to support the We Can be Heroes charity, and originally contained Batman: Arkham Asylum , FEAR 2, FEAR 3, and Lord of the Rings: War in the North. Additionally, Scribblenauts Unlimited and Arkham City were unlocked if you paid more than the average price.
Anyone who previously unlocked the bonus games, or anyone who purchases it now for more than the average price (currently sitting at $4.63), will receive an additional three games: FEAR, Mortal Kombat Arcade Kollection, and Guardians of Middle Earth.
DLC for Guardians of Middle Earth, Arkham Origins, and Gotham City Imposters has also been included.
All in all, it's a pretty tremendous discount, with money going to a good cause. You can purchase a bundle by heading to www.humblebundle.com.
