Contradiction - Spot The Liar!

"Contradiction is an interactive crime drama game that uses live-action video for the entirety of the game play. It’s a brand new take on the concept of an interactive movie and brings the genre to a whole new level of playability. Contradiction plays as smoothly as a 3D graphic game. You can wander freely around the game environment, collecting evidence and witnessing constantly changing events. However, the centrepiece of the game is interviewing the characters you meet, who can be questioned about all the evidence you’ve collected and things you’ve seen. The name of the game is then spotting contradictions in their answers, catching them out and moving the game along."
