The Battle for Wesnoth is a free, turn-based strategy game with a fantasy theme. Fight a desperate battle to reclaim the throne of Wesnoth, or take hand in any number of other adventures... 200+ unit types. 16 races. 6 major factions. Hundreds of years of history. The world of Wesnoth is absolutely huge and limited only by your creativity - make your own custom units, compose your own maps, and write your own scenarios or even full-blown campaigns. You can also challenge up to 8 friends - or strangers - and fight in epic multi-player fantasy battles.
