✯Gameplay✯

Tom Clancy's Rainbow Six Siege is a first-person shooter game, in which players control an operator from the Rainbow team. Different operators have different nationalities, weapons, and gadgets. The game features an asymmetrical structure whereby the teams are not always balanced in their ability choices. The Counter Terrorism Units (CTUs) available for play include the FBI Hostage Rescue Team, the British SAS, German GSG-9, Russian Spetsnaz and French GIGN, each of which has four operators per unit (other units were later added through downloadable content, see below). Players also have access to a "Recruit" operator who can choose from a more flexible assortment of equipment at the expense of having no unique gadget. Players pick an operator from any unit before a round starts, and are not allowed to change operators during a round. An in-game shop allows players to purchase operators using the in-game currency, "Renown", which is earned at the end of matches from actions performed in-game. The different gameplay modes award renown at different rates, with ranked matches offering the largest renown multiplier potential per match. Renown can also be affected with the addition of "boosters" which give the player a 100% increase in all renown earned for 24 hours (real time not play time). . Renown can be used to purchase weapon customization options, which allow players to put attachments such as silencers and scopes on their weapons. A premium credit, known as "R6 credits" can also be purchased using real world currency to get operators quicker in-game, or other cosmetic.

In ranked play, when a round begins, the attackers choose one of several spawn points from which to launch their attack. The attackers are then given control over wheeled drones to scout the map in search of enemy operators and targets, while the defenders can use security cameras to spot the attackers. Maps in the game are designed to encourage close quarters combat, and players cannot respawn until the end of a round. Defenders can also put up destructible barricades and reinforce walls to make them indestructible unless you have an appropriate operator. 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. Matches generally last only a few minutes.Teamwork and cooperation is encouraged in Siege, and players need to take advantage of their different abilities in order to complete the objective and defeat the enemy team. Communication between players is also encouraged. The game also has a spectator mode, which allows players to observe a match from different angles.

The game features heavy emphasis on environmental destruction using a procedural destruction system. Players can break structures by planting explosives on them, or shoot walls to make bullet holes.Players may gain tactical advantages through environmental destruction, and the system aims at encouraging players to utilize creativity and strategy. A bullet-penetration system is featured, in which bullets that pass through structures deal less damage to enemies. In addition to destruction, players can also set up heavy-duty fortifications on walls and deployable shields around them for protection; these can be destroyed through breaching or by utilizing operator specific melee-weapons like sledgehammers. In order to stop attackers' advance, defenders can place traps like barbed-wire and explosive laserwire traps around the maps.Vertical space is a key gameplay element in the game's maps: players can destroy ceilings and floors using breach charges and can ambush enemies by rappelling through windows. Powerful weapons like grenades and breach charges are valuable, as only limited numbers can be used in a round.

✯ Modes ✯

At launch, the game featured 11 maps and 5 different gameplay modes. With the downloadable content (DLC) – an additional four maps from season one and the first map from season two[needs update] – there are currently 16 maps with two more slated for release by January 2018. The gameplay modes featured include:

✌✯Hostage:
A competitive multiplayer mode, in which the attackers must extract the hostage from the defenders, while the defenders must prevent the hostage from being rescued. A secondary manner of winning can occur if the attacking or defending team accidentally damages the hostage, causing the hostage to "down"; if the opposing team can prevent revival of the hostage, and the hostage bleeds-out and dies, they will win the round.

✌✯Bomb:
A competitive multiplayer mode, in which the attackers are tasked with locating and defusing one of two bombs. The defenders must stop the attackers by killing all of them or destroying the defuser. If all attackers are killed after the defuser is planted, the defuser must still be destroyed for a defending victory.

✌✯Secure Area:
A competitive multiplayer mode, in which the defenders must protect a room with biohazard containers, while the attackers must fight their way in. The match ends when all players from one team are killed or the biohazard container is secured by the attackers when there are no defenders in the room.

✌✯Terrorist Hunt:
A solo or cooperative multiplayer mode for up to five players. Players take on the role of either attackers or defenders, and must fight against waves of enemies controlled by artificial intelligence.
✯Situations: the game's most significant single-player component, with 11 scenarios that serve as introductions and tutorials to the game's mechanics.

✌✯Tactical Realism:
A variation of the standard competitive multiplayer modes, added with the release of the Operation Skull Rain DLC. The game mode features a heavier emphasis on realism and teamwork, removing most of the heads-up display (HUD) elements, the ability to mark opponents, and the ability to see teammates' contours through walls, while also featuring the addition of a realistic ammo management system. This not featured any more but some aspects are in the other multiplayer modes.
