Cold Snap is a side mission in Infamous 2.
Cole MacGrath is approached by a woman who says that there are Icemen parading around their Militia captives. Cole must then find the Ice Soldiers abducting several Militiamen. Once Cole is noticed, the Militiamen take cover as the Ice Soldiers attack. After the Ice Soldiers are defeated, two Ice Crushers rush up and attack Cole. The mission is complete once the Crushers are defeated.
Upon completion, Cole receives 100 XP and slightly reduces enemy activity in New Marais.
