A portable barrier shield is a shield used by Pirate Commandoes in Metroid Prime 2: Echoes. It is a powerful and small energy shield that the Commandoes deploy in combat to deflect projectiles. The shield blocks all Beam shots and Missiles that Samus might fire at it. However, the shield is a double-edged sword: when deploying this shield, Pirate Commandoes cannot attack Samus using their weapons, the shield will only be deployable for a short time, the Pirates cannot use their dash systems, and Samus can simply move around their shields to attack the Commandoes from behind, or the side. Dark Pirate Commandoes do not use portable barrier shields.
