The Humble Store has teamed up with Kalypso to discount a slew of the publisher's titles for the next 80 hours (or so) as part of this week's special promotion. While you can save a few dollars off Kalypso's most recent releases – such as $5 off Tropico 5 – it's the company's back catalog that has seen the most significant price cut for the sale; up to 80% off.
Tropico 4 is down to $6 from $30; or you can snag its entire collection of DLC for $10. The sale also drops Jagged Alliance: Back in Action to $7.49, from $30.
Ten percent of sales at The Humble Store are given to charity. Humble supports multiple charities from its store, including the American Red Cross, Child's Play, the Electronic Frontier Foundation, Charity: Water and World Land Trust. The Kalypso sale ends early on Thursday, April 24.
