Well you can't have played this game at all because Rainbow 6 Siege is nothing like Call of Duty or Counterstrike, they are run n gun games, this is not run n gun but is a strategy based game where you have to cooperate with teammates, as for prefire and win that is funny because every room is usually fortified with bullet proof doors/windows and metal walls all prefiring does is give your position away and gets you killed immediately, this game is pretty hardcore a lot of times when you are hit there is no coming back but in fact with your other comment i know you have not played this game ie "if your dead you are dead no getting helped back up" well actually you can get wounded and can get medical help to get you back on your feet, one of the "operators" is also a medic that can shoot health into you from a distance, some of us have played this game for the last 6 weeks and we are trying to get more XI members playing it, so please don't put people off a game you have no idea about.
