Rook is a Runner Shell in Marathon. This shell is special, as it forces players into solo queue, meaning you won't be able to play with a team. More over, as Rook you will join matches that are already in progress. Chosing this character will also prevent you from bringing any gear from your vault. This class is a good choice for players who want a vastly different playstyle, or an additional challange.
Below, you will find an overview of Rook shell, as well as its abilities, traits, compatible cores, best loadouts and preferred weapons.
