Siege Codex
What it is
Siege Codex is a browser-based companion for Rainbow Six Siege squads planning rounds and assigning roles. Its community strategy catalog is organized by map, bombsite, and side, and published strategies require a video walkthrough. 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 assigned operator, loadout, and instructions; it stays open for one minute unless they leave or get another assignment. Team Up helps players find teammates by platform, region, rank range, comms, and schedule. The app also includes 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 or desktop environment. Match data remains online and is not saved for offline use. The free plan includes strategy browsing, squad joining, coach briefings, teammate search, and the quiz. Full Access costs $5 a month or $45 a year, and both paid options renew automatically until canceled.
