Sorry, the only (first person) shooters I've ever played are CS:GO, Insurgency, and some America's Army game WAAAAY back on my army soldier friend's original Xbox back before he ever joined the army.  Now if you just wanted to play a more general roleplay about, say, a squad of Marines or army people, etc., on a mission, then I'd be somewhat interested. I'm not too interested in the whole guns and grit part, but the interaction while in foxholes (that is what they're called, yea?) and/or back at base sounds mildly intriguing.  

You made me Google what Rainbow Six Siege even was.  I was expecting something as hardcore as Arma 3, but apparently it's more like League of Legends and CSGO had a baby?  (I only know what Arma is from SovietWomble's YouTube channel. Shows what I know about this genre lol).  

Anywho, I'm really just replying because you sounded sad in your status and I wanted to [url=https://www.youtube.com/watch?v=U9t-slLl30E]fix that[/url].
