What weapons should we introduce next?

Hey, guys. Thanks for the support for my last post, but I really need to know something:

If you were given the opportunity, what weapons would you introduce into the Halo universe, or at least Infinite?

Let’s start with the fun stuff:

I imagine we could have a flaming Needler (I said that right.) With crystals that set you on fire individually or in a supercombine.

Another one would be another modification of an old favorite, the Sticky Detonator, with an attachable stock and a trajectory projector to make shots more accurate.

Or, maybe the HMG and other lore-exclusive weapons we haven’t used before.

Maybe even a mortar of some variety, plasma or regular, to flush out campers and force them to regroup.

Let me know in the comments below.
