A video for Far Cry 3 has popped up on YouTube, and it shows around 6 minutes of gameplay on Xbox 360. In it, you’ll see a fella get stabbed from behind with his own knife; some running and gunning; the tossing of grenades; explosions; and some nice, drug-induced hallucinations. Watch it below. Game’s out in September on PC, PS3 and Xbox 360. Thanks, RPS.
