The second Humble Indie Bundle just keeps getting better–all five awesome indie games will be available on Steam for anyone who purchases the Bundle.

You still get to name your own price and the proceeds still benefit a great cause, but now Braid, Cortex Command, Machinarium, Revenge of the Titans and Osmos will be playable via Steam.

Braid, Osmos and Machinarium are available now on Steam, while Revenge of the Titans and Cortex Command will be automatically added to accounts once they debut in the Steam library.

Those who have purchased the Humble Indie Bundle can find a Steam download key on the top of their download pages. The Humble Bundle crew have a few hundred thousand Steam keys, so if you haven’t purchased it yet I’d get moving before they run out. Yeah, this thing’s that big.

The Bundle also launched on Windows-only distribution platform Desura, for those who want to be extra-indie.
