After peeking out from behind Steam's registry files earlier today, Humble Indie Bundle 4 has made its official debut. And yes, it's everything you hoped for. I mean, if this is what happens when the Bundle Wars heat up, I'm all for it.

To start off, there's Jamestown, Bit.Trip Runner, Super Meat Boy, Shank, and NightSky. I know, I know. Your piggy bank just let out a frightened squeal and then exploded. But there's more. If you beat the average price, the masters of the not-so-ancient art of indie bundling will throw in Cave Story+ and Gratuitous Space Battles. As of now, said average is just a spec over $5.00. So yes, take your piggy bank's charred ashes and make with the spending.

Some inquisitive fellows on NeoGaf have been raiding the Steam content registry for clues, and seem to have come across some entries suggesting that that Alan Wake may be heading to PC.

In further support of the Alan Wake PC release rumours, Just Push Start spotted an interview on Finnish site YLEX in which Aki Järvilehto from Remedy said "we have received feedback from a lot of PC gamers, and I have to admit that yes, we somehow ignored that. Let’s see if in the near future we could have some positive news to tell you about dating!" We love positive news about dating!

Way back in 2006, Alan Wake was the poster boy for Intel's Core 2 Duo CPU, and was regularly demoed on PC to show off its multi-threading tech. Then, all of a sudden, it became an Xbox 360 exclusive, and the PC version vanished. As a PC version was worked on heavily in the run up to its release, it theoretically shouldn't be too hard to resurrect it for a Steam release. It'd coincide nicely with the downloadable Alan Wake follow up story, Alan Wake's American Nightmare, which is heading to the Xbox 360 early next year.

It's not just Alan Wake haunting the Steam registry files. DIY Gamer have spotted evidence of a very tasty new Humble Bundle. The registry entry suggests that a new bundle may include Super Meat Boy, BIT.TRIP.RUNNER, Jamestown, Nightsky and Shank as a starting lineup, with Gratuitous Space Battles and Cave Story+ to be added after the bundle has kicked off. If accurate, that's a fantastic collection. How much would you pay for that bundle, and would you like to see Alan Wake come to Steam?

Superb indie platformer Cave Story has sauntered on Steam, boasting a sheen of upgraded graphical loveliness and a remastered soundtrack. It also comes with a few bonus modes for those who have played it to death, but still can't get enough of the endearing tale of a robot trying to save a race of oppressed rabbit dudes from "the Doctor."

Cave Story comes from the mind of developer Daisuke Amaya, and was originally made available for free. The free version is still out there if you want to give it a whirl before a full purchase (don't forget to install the English translation patch before playing). Cave Story+ is available with a 15% discount this week on Steam, which means you can grab it now for £5.94 / $8.49.
