New and Returning weapons for Infinite

i really want to talk about any and all weapons they can add to halo infinite, i already made a post talking about if the carbine were to return but now i really want more spike weapons added but how they can make them feel new? Reading up on the spiker i learned when the spikes are shot they basically burn like hell, so maybe if it were to return it could do additional burn damage. now what kinda of new spike weapons should we get?
