So in the reference guide it says:
When a yaw value of “-” increases by one, it becomes
“I.” When a yaw value of “I” increases by one, it
becomes “II.” The yaw value “II” cannot be increased.
So right now the max we can turn is "II" with our current ships, in future waves we may get a "III" ship, In this case a maneuver command would only do a "+/-" to speed. So what's the point of the arrow marks on the tool that go past "II" clicks in the current game wave?
