Darkest of Days is a FPS developed by 8monkey Labs and published by Phantom EFX / Valcon Games in September 2009 for Microsoft Windows and Xbox 360. DCodes7 found some beta differences in the promo screen shots for the game:
The character “mother” is only seen in the game as a pair of eyes on screen. In the beta, mothers eyes are green; In the final her eyes are a grey type color. In the same screenshot the panel in front of the character – witch access mission briefings – is black in the beta but a silver-grey in the final.
