Player Versus Player (PvP) is a setting found in the game. Enabling PvP on a ship with weapon systems will allow you to activate the weapons and shoot other players.

Toggling PvP has a 10 second timer, which resets when you are shot at while disabling.

Having PvP on will also put a cooldown timer of 10 seconds on removing your ship, and if you die or leave the game, your ship will stay for 15 seconds at 95% health.
