Athena Sword (March 9 2004) is an expansion which adds 19 maps (including 8 designed for multiplayer), 4 game modes, and 7 weapons. In the Steam version of Raven Shield, Athena Sword is installed separately in your Steam Library.
Note: Installing Athena Sword in Steam may overwrite `<YourGameDir>\system\R6ClassDefines.ini`. Be sure to install OpenRVS after installing Athena Sword.
Iron Wrath (June 9 2005) is an expansion which adds 18 maps (including 8 designed for multiplayer), 5 game modes, and 6 weapons. In order to add Iron Wrath to a Steam installation, follow these steps:
1. Download Iron Wrath's unpacked files [here](https://www.moddb.com/games/tom-clancys-rainbow-six-3-raven-shield/downloads/rainbow-six-3-iron-wrath-manual-installation).
1. Copy `IronWrath` and `IronWrath.mod` to `<YourGameDir>\Mods`.
Unless OpenRVS is manually ported to the Athena Sword and Iron Wrath expansions/mods, the only way to play expansion content is to join a Raven Shield (not AS/IW) server hosting AS/IW content, such as `ALLR6 | AthenaSword+IronWrath` (`104.243.46.138:7779`).
