Outcast: Legacy of the Yods is a free fan-made sequel to the 1999 game Outcast, based on CryEngine 3 (formerly known as Open Outcast).
The Modal HUD integrating the questlog, inventory, lexicon and map into one UI element. Feedback on the design is appreciated!
I love the rounded side and simple interface, however, it is too think Crysis in my opinion. Perhaps try orange or blue, this would break the usual side of the green and highlight your interface.
But this is just a personal opinion! :)
The game is based on the HUD's from the original Outcast (1999). They were all green too :)
