Dark Souls PvP (player vs player)

One of the most unique features this game has is the way players interact with each others thought the game. Special items are needed in order for players to interact with other players. With these items players can :

Leave messages for other players ,

Challenge another player for a duel,

Help another player by getting summoned to their world,

Invade another player's world.

All these features make the game world a wonderful creation.

Thanks to the creators of this game (From Software) we can truly experience a great game.
