United Front the 2nd is the seventy-eighth Extra Ops introduced in Metal Slug Attack.
Story[]
Brainwashed civilians and military personnel are going on a rampage, and no one knows why. Marco, Tarma and Eri hold a meeting to discuss how they should deal with them. A phone left behind in the room rings, and Marco picks it up. It is the Professor, who tells them that there is a treasure with a weapon capable of brainwashing people. If it is not destroyed, humanity will fall to it. Marco reluctantly authorizes the United Front operation again, looking for those who haven't been brainwashed yet to fight.
Soldiers who haven't been brainwashed yet prepare to fight, and so too does Agalia, a self-proclaimed vampire.
Agalia defeats the soldiers with ease despite being hungry. Marco is informed that the weapon is destroyed, and hears that a humanoid/actual human who was flying had also assisted. Elsewhere, the Professor chuckles, as the treasure can't be destroyed, though he is impressed that they stopped its brainwashing effects. He also got some surprising information despite being a spectator.
