Fatshark announces post-apocalyptic RPG Krater, valiantly attempts to explain it

I've watched Krater's announcement video a couple times now, and I'll be honest with you: I'm not entirely sure what it is. Now, don't get me wrong: I really like some of the things I'm hearing. A post-apocalyptic top-down RPG that's all about exploration and consequence? That's practically enough to have me hook, line, and sinker alone. But what's this about occasional perma-death? And what do you actually, you know, do ? Via Game Informer , I managed to dig up a little more concrete info:

Apparently, you'll control three characters at once in a crater-spelunking, shiny seeking search for loot and new characters. Even that, however, is subject to change, because Fatshark plans to test early and often beginning at the start of 2012. From there - based on consumer feedback - the rather unfit predator will prey on whatever features aren't fit for survival. Initially, then, the game will probably be free.
