The Battle for Wesnoth is a turn-based tactical strategy game with a high fantasy theme.
Build up a great army, gradually turning raw recruits into hardened veterans. In later games, recall your toughest warriors and form a deadly host that none can stand against! 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.
There are at least two hundred unit types, sixteen races, six major factions, and hundreds of years of history. The world of Wesnoth is absolutely huge and only limited by your creativity -- make your own custom units, create your own maps, and write your own scenarios or even full-blown campaigns. You can also challenge up to eight friends--or strangers--and fight in epic multiplayer fantasy battles.
