Signal Red is the 30th Extra Ops introduced in Metal Slug Attack.

Story:

The Professor is activating a new weapon: A Mars version of the Invaders's Brain Robot. Meanwhile, Morden prepare an offensive to destroy it. To do that, he sends a new Soldier: "VITA", a cyborg girl traumatized by her past.

Vita eventually destroys the robot. The Professor attempts to attack Vita, but is easily overpowered by her. Just as Vita is about to kill the Profesor, the red Ring Laser Mecha that accompanied the Professor abruptly arrives. The robot communicates with Vita, who leaves peacefully, before looking at the unconcious Professor.
