Gamers join more than a dozen unique operators as they fight tactical battles through destructible environments in Tom Clancy's Rainbow Six Siege. The Situations mode is a single-player tutorial, but otherwise the game is optimized for multiplayer action, with the five-player Terrorist Hunt co-op mode pitting gamers against waves of AI attackers, and the majority of the gameplay coming in the form of sieges on fortified indoor locations. One side can take hostages and set up traps to create a stronghold, while the other team can observe the fortifications and devise a plan of attack.<br><br>The barriers separating competing sides are designed to be realistically destructible, with players capable of shooting through walls, blowing holes in the ceiling, or crashing through windows, and there are no spawn points, so downed teammates must be revived. Every action gamers take (short of shooting their teammates) results in Renown, which can be used to unlock new operators, weapons, and gameplay content, while R6 Credits can be purchased with real money and used to buy Renown boosters and special weapon skins. Ubisoft plans to roll out more content throughout the year, and estimates that it will take roughly 25 hours or 25,000 Renown to unlock new post-launch operators.<br><br>Launch copies of Rainbow Six Siege include a gold weapons skin pack.
