“A shipping vessel was recently sunk leaving the region that was known to be carrying chemical weaponry and is now being patrolled by Opfor Special Ops Divers. Find the underwater wreckage and clear the area so the situation is contained.”
Just needs a few boat meshes and a container on the bottom with a few enemy diver teams and patrol boats, and you simply eliminate them. Or blow up the container, whatever.
Just something something underwater, so we can finally get to use Arma’s awesome and underutilized spec ops diving and boats!
