Tom Clancy's Rainbow Six Siege

Missions have a loose narrative, focusing on recruits going through training to prepare them for future encounters with the "White Masks", a terrorist group that threatens the safety of the world. Siege is an entry in the Rainbow Six series and the successor to Tom Clancy's Rainbow 6: Patriots, a tactical shooter that had a larger focus on narrative. The team evaluated the core of the Rainbow Six franchise and believed that letting players impersonate the top counter-terrorist operatives around the world suited the game most. Powered by AnvilNext 2.0, the game also utilizes Ubisoft's RealBlast technology to create destructible environments. The game received an overall positive reception from critics, with praise mostly directed to the game's tense multiplayer and focus on tactics. However, the game was criticized for its progression system and its lack of content. The base Counter-Terrorism Units available for play are the American Hostage Rescue Team , the British SAS, the German GSG-9, the Russian Spetsnaz and the French GIGN, each of which has four operators per unit split between attackers and defenders . Players also have access to a "Recruit" operator who can choose from a more flexible assortment of equipment at the expense of having a unique gadget or the ability to customize their weapon. A premium currency known as "R6 credits" can also be purchased using real-world currency to get operators quicker in-game, or other cosmetic items, such as weapon or operator skins . When the round begins in an online match, the attackers choose one of several spawn points from which to launch their attack while defenders do the same from which to defend from. A one-minute preparatory period will then commence wherein the attackers are then given control over mecanum-wheeled drones to scout the map in search of enemy operators, traps and defensive set-ups in addition to the target objective, while the defenders establish their defences and are encouraged to do so without having the defensive and target objective details being discovered, chiefly through destroying the drones. Maps in the game are designed to encourage close quarters combat, and players cannot respawn until the end of a round. Players who were killed by opponents can enter "Support Mode", which allows them to gain access to drone's cameras and security cameras so that they can continue to contribute to their team by informing them of opponent locations and activities.
