Rainbow six siege is a first person tactical shooter developed by Ubisoft that takes place in the modern world. Players take the role of one of dozens of special operators from special tactics and anti terrorism units from around the world including but not limited to the Canadian JTF-2, American Navy Seals, the British SAS, and the German GSG9. The game at its core revolves around Permadeath ( player only has one life) and detailed tactics among players and their squad (other players they are matched with based on skill and ranking). The game mechanics are good for the most part but can become extremely clunky when the servers are having issues. Sadly just like many ubisoft games the severs are forever plagued with issues which range from constant lag to entire regional server crashes.
