I don't know what is it with me and diamonds (or bubbles) lately, but here's another one with such a style.  I guess the overall symmetry of diamonds makes them easy to work with, but that's a habit I'll have to kick.

This is a very simple and straightforward HUD for a first-person shooter, or third!  Whichever you want.  It's not quite minimalist, but with as little clutter as possible.

The icons used in the preview image were MTG (magic the gathering) stock icons, and the M3 Predator from Mass Effect (obviously!).  The icons are not included (as I didn't design them), but all else is, and were used just for demonstration purposes.  Everything else is included in the PSD file.
