Listen up, ghouls and goblins—the new Humble Mobile Bundle is available for purchase, but since it's getting to be that time of year, it's actually the Humble Mo-Boo!-ile Bundle. There is no acceptable way to pronounce that. At any rate, there are six cool games available right now, plus one free game.
The Halloween bundle works like all the others—you pay whatever you want and can get the basic tier of games. Pay more than the average price and the second tier unlocks. The money is split between developers, charity, and Humble Bundle. This time the basic games are Rebuild, Oscura: Second Shadow, and Containment: The Zombie Puzzler. The premium level includes Five Nights At Freddy's, Dead Effect Premium, and The Walking Dead: Assault.
Give Humble Bundle your email and they'll send you a free copy of The Spookening, but that's not all. A new free game will be unlocked every few days with this bundle, so make sure you check back. The bundle is available for two weeks, but the price tends to creep upward over time. Fair warning.
