I'm thinking about picking up Arma 3 (I know, I've waited a long time), but I have some questions about underwater combat, particularly shooting underwater.
For starters, it's impossible to shoot normal bullets underwater. They don't go more than 2 meters. The bigger the gun, the shorter the distance because the bullets get ripped apart by the force. The only way to shoot underwater is with special flechette-like rounds, and even those don't go very far.
Does Arma 3 respect this reality, or did the devs just say "screw it" and create a completely unrealistic gameplay element that has no basis in reality? All the gameplay videos I see just show people shooting rifles underwater just like they were above water. I'm just not a fan of engines that defy physics.
