Sparks of War is a modded warfare based Minecraft server where the main thing is fighting other players.
It runs with a set of big mods that change how battles work. You can build custom vehicles with Valkyrien Skies and mess with rotational power stuff using Create.
It also has CC Tweaked so people can use programmable computers and it includes TACZ as the main gun mod. There are teaser videos for the server seasons too.
