There's a video game series for that.

Against Kinetic Barriers, UNSC's regular AP rounds would do nothing. Now what would be less in favor of Mass Effect would be to pair them up with Ancient Humanity or the Forerunners, but that would just be an uberstomp for Halo. And then you have the Precursors, who could kill the entirety of the Mass Effect ground and space union with a single one of their neural physics constructs (seriously, just [i]trap them in a box[/i]).

Ummm... Forerunners on the ground don't seem that tough to me. Gravity manipulation and hardlight doesn't seem that impressive against biotics.

Erm... Nigh invincible Combat skins (that would certainly take a lot more than just the ME weapons to penedtrate). Biotics require willpower whereas gravity manipulation is just "lolurtrappednow." Light based weaponry that would bypass pretty much everything ME has to offer. Teleportation (at least their AI). [url=http://www.halopedia.org/Weapon-ship]MILLIONS of Weapon-ships per warrior.[/url] Timelocks. etc.

Really depends how durable it is. If standard ME projectile weapons aren't enough, then you've got plasma weapons, and then after that you've got particle beams. Considering that the Didact was [i]apparently[/i] dropped by a grenade, I question the durability of the armor. If those somehow aren't enough, well, there's always warp. When your insides are on the outside, it doesn't really matter how tough your armor is.

A) [url=http://www.halopedia.org/Combat_Skin]During wartime, all personnel were to wear class 8 combat skins. All combatants were to wear at least class 12 skins.[/url] It can be assumed that the durability classification increases exponentially as we go up the classes (Master Chief's suit from CE to 2/3 was considered a class 2 despite the changes). Let the multiplier between combat skins increase exponentially by a factor of 2 (though it is most probably more, as Spark doesn't even notice a difference between his armors). The function modelling this would be f(x)=2^x. If we substitute 2 for x, we get Chief's suit strength to be a 4. If we substitute 8 for x, we get 256. 256/4=64. Therefore, average personnel, by this estimate, would have a strength 64 times that of Chief. [i]Sixty four.[/i] Now let's go to a class 12 skin. Substitute 12 for x. We get 4096. Divide 4096 by 4. The endurance of one standard combatant is 1024 times that of Chief (by these [i]extremely[/i] generous estimates). [i]Now[/i] let's try the max given (though the range is still far higher than this). Substitute 18 for x. We get 262144. Divide that by 4. The max endurance (though combat skins may very well go above level 18) for a Forerunner commander given these [i]extremely[/i] generous estimates, is [i]65536[/i] times the strength of Chief's armor. Those are forces to be reckoned with. B) Warp, again, is easily dodgable. And given Forerunner speeds in Cryptum (don't have the page reference, but Bornstellar was covering insane distances in the Battle for the Capital), they shouldn't have much of a problem. In addition, you should look at how the Didact survived a few Binary Rifle shots from the Librarian in the final terminal for Halo 4. C) Ignoring the one million weapon ships that would just -blam!- everything in the vicinity even if there were no Forerunners around? Why is that? D) Didact's shields were taken by Cortana during the final sequence. You can see [url=http://youtu.be/P0Ezoh7PiOQ?t=12m39s]this[/url] bolt hit him and cause a little "pop" around his armor.[/url] [quote]In addition, you should look at how the Didact survived a few Binary Rifle shots from the Librarian in the final terminal for Halo 4.[/quote] Sorry, but Forerunners [i]stomp.[/i] No idea how this is even a question.

Hard to dodge while you're being held by a stasis field. I'm not really sure why you'd assume armor would scale exponentially, since as far as I know there's nothing to back that up, but even then... [url]https://www.youtube.com/watch?v=bJNNhRGlcDE[/url]. Would the Forerunner win? Of course. Would they suffer causalities? Most definitely. There's just too many dangerous weapons that could deal some nasty damage to Forerunners. Teleporting a sword into your abdomen for instance. While conventional infantry wouldn't stand a chance, I feel like special forces could probably take out their fair share of Forerunners before going down.

A) Hard to stasis when you've been outclassed by ridiculous reaction time and are probably already dead. B) Because of Guilty Spark's comments. If there's that big a gap that it makes Chief's armor strength change negligible, I'd say it's exponential. If the gap doesn't increase between skin classes then something's wrong with the scale, considering how Chief was able to pass through even one skin classification... Mass manufactured Cains? How about those mass manufactured weapon-ships and constraint fields? If they get to manufacture and distribute their best weaponry on a large scale, then so do the Foreruunners. C) Teleporting a sword? If you use Chief's reaction time and half it (which is still not even near what the Forerunners would probably have, given their combat skin classifications- this is being VERY generous) you'd be able to dodge bullets. Not only that, but they can teleport themselves too. I'm not saying Forerunners wouldn't lose a single person, I'm just saying that the odds are [i]highly[/i] skewed towards them, and that they're not going to lose too much personnel either.

[quote]If you use Chief's reaction time and half it (which is still not even near what the Forerunners would probably have, given their combat skin classifications- this is being VERY generous) you'd be able to dodge bullets[/quote] Ehm, not to be that guy here and digress, but even Chief's full reaction time cannot evade gunfire. As seen in FoR, he aim dodged a couple bullets to his surprise. I cannot find the quote right now, but I'm sure it said something like "to his surprise he actually managed to dodge a few rounds." He's fast, but I don't think it was ever blatantly stated he was a bullet timer without Cortana.

[quote]Because of Guilty Spark's comments. [/quote] I was actually going to comment on 343's GS statement myself to further my point. If Forerunner combat armor was so damn durable, only one forerunner would be needed, not a fair number of them. It seems pretty clear to me that heavy weaponry could potentially kill Forerunners. As for teleportation, I'm talking LITERAL teleportation, not moving really fast. As of the Citadel DLC, teleportation with biotics is canon in the ME verse (it also somehow causes sterility in certain cases... lol). Having a monomolecular blade appear in your stomach doesn't sound very fun.
