atWar, formerly Afterwind, is a free-2-play online multiplayer turn-based strategy game (Silverlight). In the best traditions of Risk and Axis & Allies, you play against other people to fight for world domination. Features free unit movement - no grids or predetermined paths. Up to 20 players in a game, simultaneous turns. Another feature is the Map Editor allowing players to create their own maps and units, giving you the chance to re-enact any battle real or imagined. If you get disconnection problems with the Desura file right after you load the game then you should disable the firewall or add a firewall exception rule... or just go to our website and play in your browser there.
Ezzatam shows us how to use the Map Editor so we can create our own maps. Lesson 1 is Borders.
