If PvP has been turning you off from the sandbox world of Xsyon, Notorious Games is removing that from the equation. The developer recently upgraded their servers to include two options for players with Peace, a PvE server, and the traditional PvP server now referred to as War. Data from the original server has been duplicated for both Peace and War, so you can pick right up where you left off on your server type of choice. You can visit the Xsyon website to learn more.
