The lake has spent most of its life waiting for you to do something. This round is about the things it does on its own.
There is more in the sky. Three helicopters and three aeroplanes now, instead of one of each. One of each was an event you had to be lucky to catch; three is a sky with something in it whenever you look up, which is what a lake under a flight path actually feels like.
And the submarine shoots at them. She comes up somewhere on the plas for a couple of minutes at a time, and while she is up she throws airtanks. Nobody on this water has a gun and nobody is getting one: the tank is the weapon this game has always had, so a submarine lobbing dive cylinders at a Cessna is not a compromise, it is the correct answer. She leads them properly, which is the part that surprised us: the tank arrives where the aeroplane is going to be. About one in four connects, and what comes down comes down the way they always have, nose first and smoking, for seven seconds, into the water.
If the sky is empty she throws one at whatever boat is going past instead. Which may be yours. She is not taking sides; she is a submarine.
Freedom stops now. She works three spots in the legakkers and lies up at each of them for a minute or two before moving on. This is not a small thing: lying alongside her is how you get the water police off you, and until now she never stopped moving, so hiding behind her meant matching course and speed with a twenty metre barge while being chased. Now she is somewhere you can get to. Find her on the map and she will still be there when you arrive.
The waterplanten catch the police too. The legakker maze was always where you went to lose them, and the weed was supposed to make it a place you could not lose them quickly. It only ever slowed the person being chased, so fouling your prop in front of a patrol meant being caught on the spot, and the maze had quietly turned from a refuge into a trap. Now a patrol that comes through a bed at speed gets its own prop wrapped, for the same five seconds, with the same lack of a cure. They still catch you. They no longer catch you instantly.
And the sunset lasts. The game has always opened just before the sun goes down and it used to be dark about a minute later, which is not long enough to get anywhere or photograph anything. The day is cut into four parts now with a share of the clock each, and the sunset gets the largest share of all of them: you have well over two minutes of lit sky from the moment you arrive, and the dark part of the cycle is down to about half a minute. Golden hour is properly golden, too, the horizon goes amber and the light on the boats goes with it.
Nine kilometres an hour. Still strictly enforced, even by a submarine.
