User Demoncarnotaur on Neogaf posted Forerunner weapon screenshots that he took from the E3 coverage.
Two of these weapons we recognize as the Scattershot and the Light RIfle from the Halo 4 campaign walkthrough. The other 3, although looking somewhat similar to the light rifle in many ways, are inherently different.
Mystery Weapon 1
At first glance this looks just like the Light Rifle, but the embedded scope and light decals differentiate itself. To me it looks most like an Assault Rifle class weapon.
Mystery Weapon 2
With this weapon’s extreme length and mounted scope, it is fair to say this is most likely some sort of Forerunner sniper.
Mystery Weapon 3
This weapon looks to be much shorter in length, with some sort of circular barrel in the middle. My guess is that this will be a forerunner explosive weapon, possibly one that shoots an incendiary type grenade.
What do you guys think of these weapons?
