Situations is a single player game mode where you face off against AI Terrorist with a pre-selected Operator and loadout. This is basically the tutorial portion of Rainbow Six Siege spanned throughout 10 missions. Play them on Normal, Hard, or Realistic difficulty. There’s a very small boost in both Renown and XP when the difficulty is increased, but most players don’t think it’s worth the increased difficulty.
Each of the 10 Situations also has three objectives that can be completed to earn a star and extra Renown. The stars don’t do anything other than unlock an achievement / trophy. Renown is used for almost everything else. The eleventh situation is more like a Terrorist Hunt game. Click each situation to see a walkthrough video and the three objectives. Note: A mission does not have to be completed to earn an objective star unless stated in the objective.
