I'd personally say that there really isnt quite a tactical FPS like R6. The first time i played it, i was pretty stunned, it felt so much different compared to the usual COD expierence, it was a nice change of pace.
So, what do i recommend? i'd personally recommend you to try it out. The game isnt that expensive, and impo its worth every cent. Just dont try Ranked, trust me turts. Its hell...
