It's basically been confirmed now that Forerunner weapons will appear in Halo 4, and not just as Sentinel Beams.
This got me thinking of how exactly they're meant to fit into the existing weapon sandbox. I don't mean as whether they'll have equivalents of the Pistol and Plasma Pistol or the Rocket Launcher and the Sniper Rifle, but how as a faction of weapons, they'll fit into the existing structures, given that Covenant weapons are also likely to make a return.
By 'faction', I mean general characteristics of how that group's weapon work. While Covenant weapons are generally based on Plasma, UNSC weapons are based on Bullet.
This matters because from a gameplay standpoint, Plasma does extra damage to Shields but reduced damage to Health, while Bullet does the same amount of damage to each. Obviously, there are exceptions. The Plasma Repeater, for example, does Bullet damage, while the Spiker in Reach, surprisingly, actually does Plasma damage even though it fires conventional projectiles.
So, how will Forerunner weapons work? Well, this is where it gets interesting. What if their own weapons are the antithesis of Plasma weaponry, and actually deal reduced damage to Shields but bonus damage to Health?
This is something that hasn't been tried before, and it certainly opens up a lot of possibilities for the weapon sandbox, as well as tactical options in-game. One player grabs a Plasma Rifle, another grabs a Forerunner Rifle. The first fires to destroy Shields very quickly, but would then normally have a very difficult time actually finishing off the enemy player. The latter would normally have a lot of difficulty in actually lowering the Shield to begin with, but in this case can finish off the enemy player in the blink of an eye.
It would also make Campaign more interesting, as suddenly the player has to be a lot more aware of their Shield levels, as losing it outright is now much more deadly than previously, where Chief could lose his Shield and still have more than enough health to defeat the enemy.
It also makes sense from a canon perspective too, as Forerunner weaponry is designed to fight the Flood, which is a purely biological target.
What do you think?
