To answer a few questions:

The preorder is $14.95 - which means when 2.0 is released you can get it straight away PROVIDING you pay BEFORE it's released, which is a couple of weeks away.

Yes, lifetime updates! This is the best, it means YOU will get EVERY new release of Toribash - all the new environments, mods and EVERYTHING!

Heads will be all automatic - they will be attatched to your serial, so no more not changing your nickname for fear of losing the head!
You'll be able to colour your character sometime too. These features are only a small list of what IS going to come in Toribash.

Many new and exciting things are to come, and if you do not want to be part of this, then I feel sorry for you.
