Other notable sales include Europa Universalis 4 for $20, Shadow Warrior for $10 and Legend of Grimrock for $3.75. A full list of the current deals can be found on the Winter Sale website. So what's the catch? These deals are only available for a limited time. These discounts in particular are only valid for the next eight hours, after which time they'll be replaced by new, different discounts. There's no telling what might pop up next - an earlier version of the sale only reduced Gone Home's price to $10, instead of its current $5.
As with all Humble Store sales, 10 percent of all proceeds go toward charity. It's up to you which charity you'd like your money to benefit, though between the American Red Cross, Child's Play, the Electronic Freedom Frontier, the World Land Trust and Charity: Water, wherever your cash goes it will be put to good use helping the less fortunate.
