Though I know it is FAR too late to throw out suggestions.
It’s not too late for Halo 5 suggestions.
But it is too late for Halo 6 suggestions because of some 343i time paradox.
Anyway.
Considering how the Prometheans are so advanced and what not, it always bugged me that they never got the technologically advanced pistol that they deserved.
In my eyes, this is what they need.
A Halo: CE magnum with a sniper scope on it, fires .50 cal rounds, has a neon orange glow to it, auto-armorlock, kills anyone who says it is OP, the ability to launch Justin Beiber out of a cannon that is across the galaxy, possibly a built in smoothie maker.
Did you honestly expect something intelligent? Heck no! 343i did an amazing job and I cannot wait!
