I remember hearing or reading about this one some years ago. This looks like a good, serious tactical shooter. Its the kind of thing Rainbow Six should have continued to be. I loved Full Spectrum Warrior and though I did not play it much I enjoyed a bit of First to Fight too. We need more original R6 and SWAT games and less COD copying formats. I like a good story but they need to do both.
I still like to this day the sort of Clancyesk clinical application of the original Rainbow Six pc game when it came to how it delivered a story. Somewhat minimal but still gave you enough backstory and atmosphere to make it engaging.
