GRANT'S CAMPAIGNS — a new expansion. Follow Ulysses S. Grant from Fort Donelson to Appomattox: Champion Hill, the assault on Vicksburg, Missionary Ridge, the Wilderness and the Bloody Angle, each on the Army's own period maps. FOUR MORE FREE BATTLES. The opening battle of every campaign is now free: Gettysburg's first day, the Cornfield, the Hornet's Nest and Fort Donelson. LEARN AS YOU PLAY. Every campaign battle now ends with what really happened and why it mattered. ALSO: earthworks are now real cover, and the battle list marks the battles you've won.

New App Store screenshots showing side selection, difficulty, and the Historical Campaigns. Fixed: campaign scenarios with longer names could clip inside their card on the battle list.

The expansion grows from one battle to three. • Antietam — three scenarios on the US Army's 1904 atlas of the field, which drew a separate map for every hour of the fighting: the Cornfield at 7:30, the Sunken Road at 10:30, Burnside's Bridge at one o'clock. • Shiloh — both days on the Park Commission's 1900 survey, from the Hornet's Nest to Grant's counterattack. • Historical Campaigns now runs to eight scenarios and 225 named commands, each deployed where the surveys put them.

You asked, and here it is. • Choose your side — fight as the Union or the Confederacy, in every battle • Difficulty — Green, Regular or Veteran. Veteran does not go easy on you. • New expansion, Historical Campaigns: the three days of Gettysburg on the US Army's own 1876 survey of the field, with the real order of battle — 86 named commands, from Buford's cavalry to Pickett's brigades — drawn as period battle-map counters.

Fixes a bug where scrolling the map could drag your units out of position and ruin a battle in progress. Your regiments now hold their ground no matter where you move the camera.

Command the battle at your own pace. • Battle speed — fight at 1×, 2×, or 4× • See every volley land — casualty numbers now rise over units as they take fire • After-action report — a full casualty and flag breakdown for both armies when the smoke clears • A defender must now truly hold the field to win at nightfall: keep a position, and a quarter of your men in the ranks • Rate the game from the victory screen, or send feedback straight to the developer
