it would make sense to put in a Reinhardt like spartan into a halo game though as a little eastter egg… i mean they do have the tech for it in the halo universe so i could see it being an experimental on of shield for a specific opteration or something…
I mean they even used a ship yard gantry ship as a shield in a space battle in one of the books… (i did read a bunch of those… i think that was in the battle for reach or possibly one of the other world before that i dont remeber…)
So big *** shields is hardly a new concept… just up scale the jackal shield a bit…
