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.

I played this the other day. Having never played fallout I had no idea what any of the units did. And I won! Fantastic map, really interesting setup with the stealth units!
