Beastmasters are older Mutants who have years of experience working with Tiberium life forms. They put this unique past to use on the battlefield, each commanding a squad of Tiberium Fiends in combat. The Fiends are powerful weapons, but will listen only to their Beastmaster; if he dies, they are no longer under anyone's control, though they will not attack fellow Mutants. Therefore, commanders deploying Beastmasters must be certain to protect them while their Fiends do the dirty work of combat.
