Sometimes, You Just Need A Little More Gun

Remnant is threatened by a new type of Grimm. Will our heroes be able to fight this new threat? In their bad-ass robot Titans (Not copying anything, I swear xD) they stand a chance against this rising evil. But there are tough times ahead. Will all our heroes be able to see the end of this terror? Rated T for violence, and several OCs will be involved in the story from my other fic
