To stop an arms dealer from unleashing a deadly superweapon, Ace sniper Brandon Beckett and Agent Zero are deployed to Costa Verde to lead a group of elite soldiers against an unrelenting militia. Taking an untested sniper under his wing, Beckett faces his newest challenge: giving orders instead of receiving them.
