Wow. I just got a note about the new Humble Bundle #6 in my inbox and I knew I just had to rush to the blog to share! Included with this bundle is the amazing Torchlight, which now runs on Linux, Shatter, Dustforce (if you spend more than the average), and a few others of which I'm not familiar.
This is a great collection of games and I suggest you don't pass it up. As for me, I've got most of these games already otherwise I'd spring for it in a heartbeat.
If you needed more convincing, this bundle includes soundtracks to five of the games including Shatter's soundtrack, which is worth its weight in gold. Enjoy.
