Humble Indie Bundle #2 Has Limited Steam Keys
The second Humble Indie Bundle will allow you to activate Machinarium, Osmos, and Brain with your Stream account immediately. Cortex Command and Revenge of the Titans will be added when Valve's digital platform makes them available.
"We have a few hundred thousand Steam keys so we probably have enough to cover the whole promotion, but just in case, you might want to buy the bundle now," Wolfire explains. "If we run out of keys, there's no guarantee that we will be able to get more."
The bundle was originally scheduled to be unavailable after December 21, but Wolfire Games has extended the purchase run until 6 pm EST on December 25. The games can also be added on Desura and as DRM-free downloads for PC, Mac, and Linux.
