Good luck, Agents.
From today (November 20) through December 4, players will be able to attempt to assassinate ‘The Undying,’ but like all Elusive Targets, will have only one chance.
Those who play the mission and complete the Explosive Penmanship challenge will unlock the fan-selected Explosive Pen.
According to IO;
“The Explosive Pen is a non-illegal item that can be freely carried by Agent 47. It can be locked on to a target and thrown for a lethal kill and will explode shortly after with a powerful blast. It can also be throw to the ground before exploding. If you want, you can also conceal it inside a briefcase.”
