I heard that supposedly that the Mantis was confirmed to be in multiplayer in halo 4. This is really exciting, I have loved mech combat ever since the first time that I played Mech assault(I still have the sequel, which is an awesome game and I hope someday that day one Studios makes a Mech assault 3(or they give 343 access to a few of their mech designs for halo 5)). Even a mech gametype could be introduced as well.
For those who like to look at awesome mechs click below for some of the mechs I would like to make an appear in Halo 5(If at all possible of course):
