Well, sweet! Those who purchased the third Humble Indie Bundle are receiving another bonus, on top of the six games that are already included in the pack. Braid, Cortex Command, Machinarium, Osmos and Revenge of the Titans are now available for download if you happened to buy the bundle before 10:30 AM today or pay more than the current average price (only $4.89 right now). As an extra treat, Steam and Desura keys for access to all of these games are also included in the bundle.
I wonder how many people skipped or missed the second Humble Indie Bundle, but bought the third one. It seems like in a lot of cases, people will have extra copies of the games from the second bundle to give away or share.
