The Spectator Cam in Rainbow Six Siege offers an eleventh person to participate in 5v5 multiplayer games by watching how things play out, according to this gamescom walkthrough video.
The observer can watch the match in real-time in first-person or tactical view, which allows the player to select and automatically follow individual players.
This allows the viewer to “free-cam” over the selected player to observe their skills, team tactics and objectives.
If you missed the Rainbow Six Siege video from yesterday, you should go give it a watch as it shows off the new harbor map and the German anti-terrorism unit.
Rainbow Six Siege is out October 13 on PC, PlayStation 4 and Xbox One. If you pre-order on Xbox One, you get instant access to the Xbox 360 versions of Rainbow Six Vegas and Vegas 2 via backwards compatibility.
