You'll command not just one ship, but entire fleets, using the full range of tactics and stratagems from the period. Want to know how's it's going to play? Watch Master and Commander - and just imagine what it's like to be Russell Crowe.
Mike is enthused. "We've got a full and very detailed damage model on these ships. The cannonballs can damage the hull, they'll damage the panels they go through, they'll kill individual men, they also knock down masts, tear sails off... that obviously affects the manoeuvrability of your ships. You can tell your ships whether you want to aim at the sails or at the hull, or at the men on the decks. You can choose what ammunition to load, or even whether to board an enemy ship."
Best of all, you'll see and feel it all: the wind in the sails, the choking atmosphere of the gun-deck as the crew frantically reload the cannons, the fights on deck... the man at the steering wheel, driving the boat. Umm. Maybe we need to read up on the actual nautical terms before we start wearing epaulettes.
Reading up might indeed be helpful, because naval tactics is an entirely new subject for even Total War veterans. Learn from the experts. Such as Nelson. Or James.
"You want to cross in front or behind - it's called crossing the enemy's T. That's the classic line of battle. You want to line ships up so your gunnery faces the enemy: essentially the ships are just great big floating double-deckers full of guns. You want those rows facing the enemy. There are other tactics: doubling, where you effectively get your line of ships around the front of the enemy, and bring them around the enemy's line so you're firing from both sides."
Mike: "That's important because boats only have enough gun-crew to fire from one side at once. You're getting a two-to-one advantage."
"Exactly," says James. "That's a tactic we can get in the game. It works. Similarly, raking fire - what Nelson did at Trafalgar - was precisely the opposite. He charged in and fired along the longitudinal axis of the ships, from stern to bow (from back to front - Naval Translation Ed). Instead of the cannonball going through one gun-crew and out the other side, potentially it could plough all the way along the decks, and take out nearly all the gun crews in a single shot."
