I just bought Ground Branch in the current Steam sale for 17,5€. Although early access it's very true to the original Rainbow Six/Rogue Spear and Ghost Recon feeling. Especially Terrorist Hunt is a blast and finally a game with an oldschool like multiplayer lobby and you can even locally host games .
After some required server upgrades the original *DAMN R6 website is online again.
The forum still had some issues with the new settings but currently it seems to work again.
The *DBL page shows tons of errors and eventually I gonna remove the error log once all other issues are resolved but at least you should be able to browse it.
Even after 3 years I'm playing the hell out of Squad, which has the most playtime by far among any steam/uplay/origin game I own. Yet I think I still played more R6 and Ghost Recon, at least combined.
Check. Had to reverse the PHP Upgrade. I only managed to get it in read only mode. Have to figure the rest out. In the meantime the *DAMN R6 Startpage is not working anymore because my provider forced a PHP warning on any page which kills the page…
