Cognition: An Erica Reed Thriller – Episode 3: The Oracle (PC) continues forward with the strong momentum of the previous two episodes. The use of one main location (along with the ability to actively participate in memories that took place in this location several years before) condenses the story into a potent murder mystery where questions continue to arise. Why is the killer doing this? What do Erica’s visions mean? Who is Jeff Therrien? Some of the puzzles fall into the adventure game trap of being clear to the developers but not to the player – even when exhausting the hint system – but the ending is startling and perhaps most important of all, earned. Episode 3 admittedly has some rough edges, but it delivers where it counts. Playing the final episode will be a bittersweet experience indeed.
