The team at Humble Bundle started the trend of offering games for a limited time on the "pay what you want model". So far the previous bundles have generated millions in revenue that are shared by various game developers. Today, the team has launched Humble Indie Bundle 5 with a new set of games to get on the cheap or as much as you can afford.
The games that are a part of Humble Indie Bundle 5 include the classic Double Fine action-adventure game Psychonauts, the survival horror game Amnesia: The Dark Descent, the unique 2D platformer game Limbo and theSuperbrothers: Sword & Sworcery EP. If you decide to pay more than the average amount as listed on the Humble Bundle site, you will also get the action-RPG game Bastion as part of the bundle.
As with the previous Humble Indie Bundle events you can also choose to donate money to two charities, the Humble Indie Bundle 5 will end two weeks from now.
