Battlestations: Midway is set in the Pacific Theater of Operations during World War II. In the single-player campaign, you play as Henry Walker, a Navy recruit who shows up at Pearl Harbor just in time for the Japanese attack in December, 1941. From there, your skills as a commander are put to the test in historical battles such as the Battle of the Coral Sea and, eventually, the Battle of Midway. Between battles, you'll see rendered cutscenes intended to develop a story about Henry Walker's rise through the ranks to eventually become the captain of the massive aircraft carrier known as the USS Yorktown. The dialogue in the story is forced and almost comically bad at times, but the characters do a decent job of personalizing the battles, and it's gratifying to see your recruit go from cruising around a harbor in a tiny PT boat to commanding fleets of ships out on the open sea. There are 11 missions in the single-player campaign, and although some of those missions can easily take the better part of an hour to complete, you can easily finish the campaign in four or five hours. There are 10 extra challenge missions focusing on specific types of units from both the Japan and US forces, but the challenge missions aren't as exciting as the larger story battles. Despite these bonus missions and the inclusion of a very good online multiplayer game, it's disappointing that the single-player campaign is so short.

Although all the battles in the game are sea battles, there's enough variety in the missions and the units at your disposal to provide a unique experience each time you play. You usually start out with a handful of units at your command and a few simple objectives, such as destroying all enemy carriers or defending your airfield. From there, it's entirely up to you how you go about completing your objectives. For the larger battles, you'll probably find yourself spending most of your time looking at the tactical map. It's a small map of the battle area that shows you everything you need to know at a glance. Using this map, you can command all of your ships, subs, and planes to move and attack. It takes a short while to get used to using the map and commanding sometimes dozens of units at a time, but the level of detail isn't so fine as to require excessive micromanagement. The artificial intelligence in the game works very well, and you never have to worry about your units disobeying orders or behaving irrationally. The artificial intelligence is so good that in the larger battles, you'll find the best strategy is to spend about 75 percent of your time commanding units from the tactical map.

The other 25 percent of your time will be spent directly controlling your units, which is every bit as fun as commanding them from afar. At any time, you can take control of any of your units and do the dirty work yourself. You can captain a sub as it stalks an enemy cruiser, take to the skies for an intense dogfight, man the antiaircraft guns on the deck of a battleship, manage the operations of an airfield or shipyard, and more, all in a single battle. The units all have unique controls, weapons, abilities, and limitations that you'll need to learn so as to make the best use of all of your forces. This isn't a simulation game, though, so it doesn't take very long to get a feel for each unit under your control. The ships, subs, and planes don't handle realistically at all, but they are at least fairly well balanced against one another. You can feasibly take an all-action approach to battle and forget about being a commander, but without proper support, you'll have a hard time winning any battles. Taking a hands-off approach works better for developing a strategy, but even then you'll want to jump into the action from time to time. There's a simple but very distinct pleasure to be found in piloting an airplane and swooping in out of the skies to dive-bomb a battleship or pelting the hull of a carrier with a volley of torpedoes from a submarine.
