Join if you want a blood bath. SIA is built around heavy PvP, with factions choosing an empire to join from 11 different colors. It sounds like chaos because, well, it is.
Expect realistic guns, constant fighting, and a survival-style setup with economy commands like /shop and /sellgui to keep you stocked. There are also 90+ plugins in the mix, so there's plenty going on behind the scenes.
If you like faction wars, fast combat, and a more brutal server vibe, this one is for you.
