Now, this is one awesome Arma 3 video. Why is it awesome you ask? Just by the thumbnail alone, you can tell that it’s going to be in a very interesting battle. The Shack Tac team appears to have created a custom-made fortress out in the middle of some Snowy Mountains. Definitely, a cool video to check out. If you know anything about the Arma 3 editor creating a fortress of this size or just a custom fortress, in general, can be an absolute nightmare and can be very glitchy when it comes time to actually play with it.
