DUST 514 beta, you'll want to have a look at a fan site known as DUST 514 Base. The site posted a detailed look at the game's vehicle fitting interface over the weekend, and it gives a good rundown on many of the options in store for the planet-based mercenaries of New Eden.
If you're an EVE Online veteran, the fitting screens will seem somewhat familiar. If not, at least you can get a leg up on what is likely to be one of the more complex console FPS UIs in the business.
The blog entry contains a fair bit of speculation in terms of the numbers presented on the UI, and there are also plenty of high-quality images augmenting the text. Hit the links below for more info.
