VEIN servers can modify the pvp settings to their liking, allowing or disallowing damage to other players entirely. This allows for creating cooperative or competitive environments on VEIN servers, which can be ideal for private servers aiming for a specific playstyle. Player vs player is one of the many gameplay options available via the engine configuration file, along with time or damage multipliers.
