Humble Indie Bundle 3 is offering a not-so-humble collection of games. The current offering has been expanded yet again, this time with a new PC & Mac-compatible game: Steel Storm: Burning Retribution, a top-down shooter inspired by classic shmups of yesteryear. With this recent addition, you can now pay whatever you want for a collection of six indie games.

If you're already purchased the Bundle, you don't have to worry about missing out on this offer. "If you've already bought Humble Indie Bundle 3, just go to your download page and it will show up next to your other five games," an e-mail message sent to purchasers says. If you've already redeemed your code on Steam, you'll find the game automatically appears in your library.

Previous Humble Bundle's were packed with additional games over the duration of the promotion.

In addition to Steel Storm, Humble Indie Bundle 3 currently offers the Humble Indie Bundle offers DRM-free versions of VVVVVV, Hammerfight, Crayon Physics Deluxe, Cogs, And Yet It Moves, and a demo of Minecraft. Since the program's start, over 200,000 people have purchased the bundle, raising nearly one million dollars of revenue. The offer expires in 8 days.
