This classic beauty of a game is still online with modern updates!
You just need the multiplayer patch to play online.

We also run Athena Sword, Iron Wrath, Rogue Spear and original Rainbow Six maps and of course custom maps on our servers. Brand new maps and weapons, items and terrorists to fight as well! We also have many improvements to graphics and HD hit effects etc.

1) OpenRVS 1.6 Update Is Here (32kb) (Feb 2024)

2) Get the Sound Update so you can hear proper multiplayer sounds from custom maps and expansions

3) If you want, we HIGHLY recommend that you get the Optimization Patch as well. It will help run the latest maps smoother and it fixes a lot of issues with Windows 10 and modern PC compatibility.

Just copy Mods and System folders into your Rainbow Six 3 Gold or Raven Shield folder.

How to install the update:
1. Close the game, close Steam or Uplay
2. Install to your Rainbow Six 3 Gold or Raven Shield folder. Run the patch as Administrator.
For example if you have the Steam version you would go to:

C: > Program Files > Steam > steamapps > common > Rainbow Six 3 > system

or

C: > Program Files (x86) > Raven Shield > system

for other versions.
3. IMPORTANT! Set your connection speed to T3 in the Multiplayer Options
4. Go to Multiplayer > Internet (not LAN) and hit refresh to see the servers then Play!

OTHER TIPS / INFO:
• I suggest 1920x1080 resolution for most people this looks the best.
• Right click Ravenshield.exe - Properties - Run As Admin and Compatibility for Windows XP SP3

• WINDOWS ISSUES: Sometimes it does not install to the game folder.
* MAKE SURE GAME IS CLOSED. Close STEAM or UPLAY too.
* If it still does not work (W10 sometimes), manually install the patch. Just install the patch to a folder on your desktop. Then just copy and paste the inside folders (sounds, armpatches, system) to your game folder. Done!
