The essential core concept of EVE Online is that it is full time PvP in a sandbox
environment. As has been mentioned in previous sections any player can
engage another player at any time in any place. In high-sec space there
may be consequences if a pilot attacks another without just cause, but they
can still make that attack if they wish. In low-sec and null-sec, there are no
limitations to PvP at all. Some of the wide variety of PvP styles are described
in more detail below.
