Kalypso Media’s charitable Humble Bundle deal is currently offering gamers the chance to pledge as little as $1 for three Steam games, Deathspank, Deathspank: Thongs of virtue and On the Rain Slick Precipice of Darkness Episode 1 which is incredible value. The offer lasts one week, but gamers are invited to pledge more, and decide where their donation goes to – split three ways between Kalypso, the developer and the charity. Looking at the stats which suggests over 30,000 donations since the promotion went live yesterday (17/09/13), the average pledge is around $4 but if you’re feeling generous, then offering a minimum of $6 will grant an extra game, On the Rain Slick Precipice of Darkness Episode 2.
