To play Samurai Wars, just download "Savage: the battle for Newerth" from Desura and launch the game. Once inside the game, click Play and look for servers with the Type SAMURAI to play the game.
A few servers a running 24/7 with the Samurai MOD.
With so many people out there interested in medieval Japan, we hope that the MOD will gain some traction in the coming weeks. See you in-game!
