The Battle for Wesnoth is an open source, turn-based strategy game with a high fantasy theme. It features both singleplayer and online/hotseat multiplayer combat.

Delve into the darkest depths of the earth to craft a jewel of fire itself... Defend your kingdom against the ravaging hordes of a foul necromancer... Or lead a straggly band of survivors across the blazing sands to confront an unseen evil.

The choice is up to you...
