I was in Death Room a few hours ago and this guy was firing twirling streams of a white powdery gas into our spawn from his. It was like the wake behind a rocket. It had the effect of gas but it wasn't gas. I didn't see how he was firing them because he was ghosting. After the 1st death we couldn't respawn but it wasn't killing us. It just kept going through the respawn process. It wasn't life taker that much I know because we didn't get deaths.
