Figures I'd forget to post the site.
Here's the "Trying to sell you the game" website

And here's the much more useful community site

Any and all info can be found at the second site. The first will just give you a basic idea of what the game is like, then forward you to JOSSH.
You can also download the entire client from the registration page. Comes in either a 121 meg file or 51, depending on whether or not you want movies and sound. I've been experiencing trouble registering today; I don't know if this is an issue at my end or if their reg network is down for now. You can still download the game and experience a bit of it offline, like Tribes. The flight physics the game uses are really neat. Might wanna play offline for a while to get used to them.
