Rainbow Six Extraction, the co-op title that started as a spin-off mode for the popular competitive FPS Rainbow Six Siege, has gotten pushed back a little bit. During E3 last month, Ubisoft announced that the game - which was previously known as Rainbow Six Quarantine, and Rainbow Six Parasite before that - would launch on September 16 this year. A few days ago, though, Ubisoft announced that they would need just a little more time to get it done.
