Grenades - I just finally figured out how to throw them!
I love this game at 32 hours in. It's brilliant!. But in most games, you would throw a grenade either with one of the shoulder or trigger buttons, or perhaps an A, B, X or Y (X, circle, square, triangle) thing. It's hidden in the menus! Consequently? I also just learned there are binoculars! I learned this after prepping to leave Toshara, because I'm doing a final mission where you have to open and use a holo to find a location. In that menu I found these missing things I had never figured out lol.
