If you ask me, Binding of Isaac was -- bar none -- one of the best games on PC last year. The blood, sweat, and tear-soaked roguelike shooter Zelda Robotron thing sounds like a grotesque hybrid on par with its own hideously mutated enemies, but it fits together gloriously. And now, if you skipped it, you have no excuse -- even if you rely on archaic box technology to deliver your games, and not merely your pizza, as nature intended.

The retail version (pictured) will come loaded with a DRM-free copy of Binding of Isaac, a free Steam gifting key, a soundtrack, a poster that I'll awkwardly attempt to explain to friends and family, and a 40-page "Devzine". Unfortunately, though, it's UK-only for now.

For everyone else, however, an interview with the Indie Games Blog saw Binding of Isaac creator Edmund McMillen divulge loads of details about the upcoming expansion, Wrath of the Lamb.
"My goal is to try to trick up myself, once again. There obviously going to be more of the same, I think I added like 50 items, 20 trinkets (which are a whole new set up), and then as much rare and random happenings as possible. There's basically two paths, there's an alternate chapter per chapter. What I've shown is the cellar, which is an alternate to the basement. So you could start your game, and it might be cellar 1, which has different enemies, different rare rooms, different bosses, different random happenings that are going to be new to the mix."
"Part of it too was annoyance with people saying "your game is too easy, I beat Satan in like 5 seconds". So the final ultimate chapter in the game, I don't want to spoiler it but whatever, there's an alternate chapter to Sheol which is much harder. That will have the true final ending. Then you'll be rewarded by beating that part of the game with each character with items that are really unique."
"There's a lot of really unique items, new items sets, even new player statistics. There's a speed of shot stat, not just rate of fire, that can actually be modified now, which is cool to mess around with. There's also a bunch of new tear types that goes with the items."
McMillen's aim, then, is to keep Binding of Isaac beatable in the same amount of time as before, but with even more mind-warping insanity. Given that I've already cried enemies to death with tears of blood and battled a worm beast that eats its own excrement, I'm pretty damn excited. And if you've never played Binding of Isaac, you now probably think I'm a crazy person.
