Oh yeah, I got so into that game. That and Cluefinders. I used to be quite bad at shooters, but then I started playing Arma 3 and it changed me a lot. The realism was fantastic and I loved sniping. Now, a few hundred hours later, I'm half decent at shooters.
Congrats on winning by the way! Just hit me up on discord or my email and I will shoot you that key. Might have to do it in the morning, since I'm crashing right now. I have a really early student to tutor, so I gotta get some sleep.
