The Humble Bundle people have been outrageously busy this year. Not only do they have their mainstay "Humble Bundle" but now also have a store and weekly bundles. Yesterday they started up a new promotion called the Humble Daily Bundle which promises to provide a different bundle every 24 hours. The first set was a return of the Deep Silver Bundle.
Today the bundle in question is the Humble Daily Bundle from Outer Space. It's a tad less impressive, offering only three games in all. Paying what you want (over $1) grants X3: Terran Conflict. Beating the average price adds Universe Sandbox. Finally, paying over $10 unlocks Early Access title Kinectic Void. Each game includes a Steam key.
The Humble Daily Bundle is a two-week only event. Most bundles will be brand new but more past bundles may pop up!
