The Battle for Wesnoth is a turn-based strategy game with a fantasy theme.
Build up a great army, gradually training raw recruits into hardened veterans. In later games, recall your toughest warriors and form a deadly host against whom none can stand! Choose units from a large pool of specialists, and hand pick a force with the right strengths to fight well on different terrains against all manner of opposition.
Wesnoth has many different sagas waiting to be played out. You can battle orcs, undead, and bandits on the marches of the Kingdom of Wesnoth; fight alongside dragons in the lofty peaks, elves in the green reaches of the Aethenwood, dwarves in the great halls of Knalga, or even merfolk in the Bay of Pearls. You can fight to regain the throne of Wesnoth, or use your dread power over the Undead to dominate the land of mortals, or lead your glorious Orcish tribe to victory against the humans who dared despoil your lands.
