It's a decent HUD, I am just confused by the clear misinformation.
An evil hack of the Basic M1 HUD (as included with most A1 releases), but it has transparency, and is decorated slightly, so it's awesome.
Does Basic HUD's opaqueness get in your way? Do you like Enhanced HUD, but just can't get past the lack of the inventory panel? Then this might just be for you! Comes with tiny little weapons displays that just seem to morph into other shapes inexplicably. The UESC is crazy!
No refunds.
Get it for Marathon 2/Marathon Infinity!
Alternatively, get it on the Workshop!
