Armor penetrating rounds are just normal bullets used by militaries. Dunno why so many science fiction writers, both in fanfiction and novels, treat them like they're special. If it's not armor-piercing, then it'd be something like hollow point or explosive or incendiary. The normal bullets that aren't designed to penetrate armor are just used for practice or by civilians since they're cheaper.

That asari wouldn't be grunting in pain nor flying through the air. Her body would have been literally torn into a gory pulp. It's a freaking grenade. And, just like with the bullets, her barriers (assuming they're even up still) would have been utterly useless against it. Plus, of course, the concussive force fucking up her insides and brain even if her barriers and armor magically protected her.

The ME weapons do not have tracers, they either are glowing from friction with the air (most likely) or are charged by electricity used to accelerate them (unlikely as they are accelerated through mass effect fields, not electromagnetics).

Actually, kinetic barriers are tuned in the lore that they would very easily activate against bullets. They activate against any mass moving a sufficient velocity that, for that mass, is dangerous. However, they would be totally useless against even modern bullets due to how kinetic barriers work. They project a field of mass to counter that of the incoming mass. They struggle to stop just a few shots from bullets with something like one fourteenth the mass of a grain of sand and can only stop a few such shots. Their armor likewise can only take a few hits from it. Needless to say, their barriers and armor are utterly useless against the mass of modern bullets. This probably applies to naval combat, including even modern cruise missiles and aircraft launched bombs. Meanwhile, human body armor, vehicles, defenses, etc. are geared for handling this stuff. Which means it's basically invulnerable against Mass Effect weapons.

The greatest weakness of the Mass Effect setting is that the writers at Bioware are stupid. Creative, imaginative, but stupid. They made a highly advance sci-fi setting that would be effortlessly curbstomped by any random African warlord.

"Just because the people approve of it doesn't make it right!"
True, however, killing pirates is always right.

Oh, that is great. A spooky hand referencing the devil extending a hand comes out from a door. And Harper simply sticks a grenade in it.

like how you mixed halo and mass effect

please tell me your not killing liara off

like that you made Ronald Taylor better than he was in me2

you've said Spartacus was on the phone to his wife and then that he lost his wife in the same chapter

thought you should know, enjoying the story though

This is one of the best ME AU stories. Don't let it die.

POLYUSHKE POLYE! *Su25s rocket overhead, Malashenko raising his arms to the sky*

Overall the idea is solid but your writing skill is far below the level needed to execute it. If you decided to abandon the story that is probably for the best, at least until you've improved. The amount of broken grammar, incorrect spelling, telling and not showing, it's too much to ignore.

Hope this updates

were the last line inspired from Game of thrones it's really similar to what Arthur Dayne and Ed stark at the tower of joy. Also from a chapters before "You know nothing". Also the author notes was really helpful I was gonna criticized with the number of plots happening it was getting hard to remember it all.

Also I feel that biotics is underutilized a bit new techniques could've been invited with Humanities infinite imagination maybe like instead of a biotic sphere have it as a shield then use charge like Juumonji Katsuto from mahouka koukou no rettousei. Maybe even have an Oc who is like obiwan kenobi above average power but really strong control over the power

Fairly interesting idea; Poor execution.

Subpar grammar; awkward dialogue; annoyingly "speshul" OC in a universe rich with beloved characters; little to no research into the science part of "science fictionespecially necessary when humanity isn't going the Eezo routetypical 'council is made up of mentally retarded, 1-dimensional cutouts' instead of being intelligent career politicians and galactic leaders; unrealistic population sizes vs. amount of colonies, little to no understanding of how military structure/ranks/logistics/deployments/fleets work (even half an hour would have made a massive difference in believability vs. 'suspension of disbelief').

While far from the worst fic I've seen, it's also very far from the best (or even above average). The biggest criticism is the lack of any research into any aspect the author doesn't understand/know. No one is expecting an expert on military tactics and logistics, or a doctoral level of understanding of physics (I'm not even expecting a highschool senior level of understanding here), but the apparent unwillingness to do at least SOME research drags this fic down to a level that it's almost unreadable.
No one is expecting the next "Transcendent Humanity" or "Mass Effect: Logical Conclusions", only the most basic competence. But even that is apparently too much to ask.

I'm feeling second hand embarrassment for humanity with all this singing.
