Beginning today, the folks at Humble Bundle are rolling out a new group of apps, this time with a spooky theme. Not only can you pay what you want to get this Android-exclusive group of Halloween-themed games, you can also grab one of the popular titles for free.

The Spookening is being offered for free this time around, bringing a spooky 3D gaming experience to your Android device. To download The Spookening, hand over your email address on the site, and continue on with the download.

Here are the games included in the “Mo-boo!-ile Bundle”:

• Rebuild
• Oscura: Second Shadow
• COntainment: The Zombie Puzzler

If you’re so inclined to pay more than the average ($2.79), you can unlock 3 more games, including:

• Five Nights at Freddy’s
• Dead Effect
• The Walking Dead: Assault

Remember, not only are you receiving these 7 games for a very small price, but part of your money also goes towards charity. With that being said, it’s pretty hard to resist these horror-themed games! Which is your favorite game out of the list above? Any particular one that’s driving you to pick up this bundle?
