DISCUSS GUYS!!!
A compact, Forerunner SMG would be most welcome!
Maybe in the feel and style of Crysis 2’s “Feline” SMG.
Forerunner bow? As in a long bow or crossbow? That would be…odd.
The Promethean Repeater was mentioned in one of the weekly bulletins.

> Among other things, the Campaign demo introduced a brand-new enemy class – the Prometheans. The Prometheans are an elite Forerunner warrior class tasked with defending Requiem. Similar to the Covenant, the Prometheans feature a vast variety of different species with sophisticated tactics, technology and unique abilities. The demo also revealed a first look at three Promethean weapons: the Light Rifle, <mark>Repeater</mark>, and Scattershot, all of which will be available in campaign and multiplayer.
Light automag forerunner FTW along with the forerunner sniper.
