Ardent Seas blends modern naval combat with classical RTS gameplay, featuring Aliens, space lasers, and unholy amounts of missiles
Because CIWS in action are hard to capture, here are two screenshots at once of the changes recently made to the Cruiser.
Previously, its quad anti-aircraft cannons could only fire at aircraft. They're now able to fire at both aircraft and missiles, in order to boost their "missile shield" function.
This kind of reminds me of the naval battles in Act of War.
I've never actually played Act of War: High Treason, so I'll take your word for it. I've only played Direct Action.
