Curse started a few years ago as a Half-Life 2 mod. With a setting inspired by ancient Egypt it offered a first person adventure where combat was secondary to exploration and solving environmental puzzles. The creators now utilize the Unity Engine to redefine the experience as a full game for Windows and Mac, where a dead Pharaoh attempts to discover the truth behind a myth concerning immortality. The first teaser of this new direction is here.
It certainly doesn't show a whole lot of the game but it's good news for anyone who was getting worried about the previously seemingly uncertain fate of this promising project.
