What Siege Codex is

Siege Codex helps Rainbow Six Siege squads coordinate rounds by selecting strategies and assigning each player an operator and job. Its community strategy catalog is organized by map, bombsite, and side; a strategy needs a video walkthrough to be published. Players can also create strategies with operator assignments, loadouts, instructions, images, and video, then keep them private or publish them. The Coach Board sends a player a briefing with their loadout and instructions when an operator is assigned. That briefing remains open for one minute unless the player leaves or gets another assignment. Team Up helps players look for teammates by platform, region, rank range, comms, and schedule. The app also has a timed Siege Quiz and a strategy vault with ratings. It runs in desktop and mobile browsers and can be installed on a device's home screen, Dock, Start menu, or desktop. Match data remains online and is not saved for offline use. The free plan includes browsing strategies, joining a squad, receiving coach briefings, finding teammates, and taking the quiz. Full Access costs $5 a month or $45 a year, with automatic renewal until canceled.
