O Terrorist Hunt Mode(PvE): Terrorist hunt mode is the game mode that allows you to test your skills and teamwork with the whole team playing against automated bots. O Situation Mode (PvE): Situation mode is a single-player mode to help you test your skills in different combat styles with short term objectives. There are three modes in Rainbow Six Siege that have short-range objectives and not any campaign or long objectives. Since short modes were missing in Rainbow Six: Patriots, Ubisoft decided to come up with a dedicated game focused on short modes and multiplayer gaming that allow you to team up and play against pre-programmed bots or live players in multiple modes. Rainbow Six Siege is a successor to Rainbow six: Patriots that had more emphasis on campaign mode. Rainbow Six: Siege is an online tactical shooting game that offers both first-person and third-person perspective for the players according to their style preference.
