The Repopulation's going to have two distinct server rulesets when it eventually launches. Option one will be a standard PvE-focused environment with optional PvP and associated flagging mechanics. "The standard ruleset should be suitable for most types of players. You have a full compliment of resources and PvE tiers available in protected areas," explains the latest Repopulation dev diary.
If that doesn't sound like your cup of tea, Above & Beyond Technologies is also hosting an open PvP ruleset with corpse looting, friendly fire, and EVE-like security sector mechanics. Some of the details are still being ironed out, but you should definitely read the lengthy new dev diary that lays out the particulars for each rule set.
