Although building this beast on your own would probably be an unlike-to-accomplish to task, the guys over at Man at Arms: Reforged built a Gravity Hammer straight out of Halo...from scratch.
Check it out, and notice how heavy the hammer looks, too!
So, are you going to get started fabricating a replica Gravity Hammer with your plasma filter, steel, leather, and all the rest? Or are you just going to stick to Halo 5?
Halo 5 is available now for Xbox One.
