This is a modification of Hopper's amazing XBLA HUD for Marathon 2 and Infinity, this time designed for Marathon Phoenix.
Note: Secret skull information is displayed when you take out your fists.
Initial release. Includes support for secret skulls and keycards.
The reason I'm giving it three stars is because the Shield/Oxygen bars don't work on the latest version of Aleph One. Everything else works though.
I mean, duh.
