This mod is truly a gem. It combines a great emotional story with deep psychological terror and pulls both of them off beautiful .suspense and deep mental illness both add to this games artistic polish, this combined with a fast paced secondary campaign complete with custom weapons textures npcs voices left me blown away. i havent had this depth in a gaming experience since i first played half life two. great work, im eager to see where your talent takes you in the future
