I can go find the quote in the manual.
Edit: "The Covenant seem more vulnerable to these weapons, so take advantages of this weakness whenever possible." (page 20)
My point still stands forerunner weapons could do more damage to Prometheans.
The condition of the skull wouldn't matter for some of the stuff I pointed. For the eye sockets you could say they broke away, but the Prometheans doesn't look like that. It would either be a deformity on a human or not a human. And the size of the teeth really has no explanation if it is a human other than artistic error. The mandibles could have also broken apart but they just look really chiseled, though that could be a human trait.
They would have had to have changed the carbine to put it into SWAT. People are just going to grab a carbine and spray like crazy hoping for a headshot.
So you are throwing their story telling our the window before the story even comes out. What it seems you are doing is demanding answers right now for some trivial part of the game. Maybe you should wait, play the game, then decided if their is a logical inconsistency or not.
From the end of Reach to the end of Halo 3 is just a few months. So that isn't nearly enough time to decommission a weapon and fully replace it with a model that is just an improved version of a 30 year old gun.
It is perfectly reasonable to have both weapons, today we have many weapons that are similar like the M4 and M16, yet we use both of them.
Forerunner's can come in many sizes. I never got the impression that many of them were too much taller than 2 meters.
Anyways, the teeth don't seem to match that of a humans. It looks like they are too big and not enough.
Here is a human skull
It seems pretty noticeable that the teeth on the Promethean are different than a humans. Also the human eye sockets look smaller, and the jaw bone looks less defined.
Chief is also wearing Mk IV and not Mk V so we don't know how they react differently. And I'm pretty sure 343 said that Chief stopped somewhere else during those four years which explains the armor changes, but they didn't want to go in depth with the interviewer.
I like how you can hold a one handed weapon with the flag now.
And the whole oddball moment seemed awesome. We can chuck the oddball to other people, and then disintegrate them with an assassination.
The hardlight shield is like a Jackal shield, except it fits most of the spartan, but there is a little area exposed on the bottom, and the back is completely exposed. You hold it on your arm so you can't use weapons.
I will be slightly upset if the Covenant's CGI looks good, because they could have used it for everything. The costumes the marines use don't even look similar to anything we've seen before besides the helmet, and maybe the shoulders.
I didn't even pay much attention to the ranking system in Halo 3. I just liked playing the game. In Reach's I pay more attention to it because it is needed to obtain new armor, where only a few armor pieces were obtained that way in Halo 3.
The only time they were annoying in Reach was when the whole team threw them at you.
Frag grenades were just scare tactics or a hope to lower their shields quickly.
Plasma grenades were only really effective when they stick to people.
