Is Mister Torgue in the chapter you're reading? Then it's probably a hilarious moment.
When Brick approaches Tali while she's being attacked by Fist's goons, she tries to shoot him, thinking he's another bandit. He yanks the shotgun out of her hand, so she draws a pistol from her SDU. Brick grabs that gun too. Then she draws an assault rifle, and he snatches that. Then she draws a sniper rifle, and he knocks that out of her hand. Then she draws a rocket launcher.
To elaborate: Mr. Torgue's first appearance in the fanfic consists of him speaking in nothing but caps, blowing up ten floors of his own headquarters, and shaping the resulting explosion into a giant middle finger leveled right at Maliwan and Hyperion's headquarters. While playing air guitar, no less.
THAT IS HOW TORGUE-URDNOT DOES BUSINESS, MOTHERFbleepERS!!
The sheer amount of Seen It All from the people on Illium.
Massive gunfight raging in the building next door to the trading hub. Some people flee. Others? They just activate kinetic barriers and keep on trading.
Moxxi off-handedly mentioning that she has special insurance to protect her bar from human-related violence.
When Niftu Cal enters the Dantius Towers and starts throwing Eclipse mercs around, human and turian onlookers start taking bets. When he hurls a giant desk into the next wave of Eclipse mercs while shouting his status as a BIOTIC GOD, they respond by betting even more.
And according to Char-Nobyl's scene in Chapter 10, overlapping corporate raids are technically classified as natural disasters by Illium insurance companies.
Some of the displays of awesome badassitude are hysterically funny just because of their unexpected source. Take Ambassador Udina nonchalantly wiping the walls with Nine-Toes, for example. Or Niftu Cal effortlessly plowing through a pile of mercenaries.
'Splode-hacking. The only way Mister Torgue hacks things is when it results in the target's IT team screaming because their faces got hacked.
When Lilith needs to contact Okeer, she asks everyone who has any tech-savvy to help out. The whole team starts activating their omnitools...including Bloodwing.
Lilith: Wait, your bird has an omnitool?
It's worth mentioning that thanks to the various fans screwing around, making headcanons, and pointing out Fridge Brilliance, the Spacebattles threads for the story are also hilarious. Highlights include realizing that mooks are issued white gear because it's cheap and not worth looting and because their bosses realize how expendable they are, realizing that the human equivalent of insurance comes in guns, (Doctor Fluffy: So that's why Hyperion has a line of sniper rifles known as the Policy) The crowning moment, however, is likely everyone's reaction when someone realized that Nazara/ Sovereign is a PSYCHO-SIREN-REAPER.Hilarity and Freak Outs abounded, for well over a page, punctuated by notes from the author that "mine is anevil laugh".
When Nassana is finally killed, everyone starts cheering, looting the body, or catching their breath. Then Zaeed points out that they needed her encryption key, which likely didn't survive the explosion.
Let me get this straight. If what I’m hearing is correct, the most important documentation regarding synthetic-organic relations, and evidence that could lead to lasting peace between humanity and the geth… is a podcast.
This line when Gaige offers to "upgrade" the damaged Geth-Buddy you can almost imagine the panic in their voice.
"This platform is not available for experimentation," Geth-Buddy hastily said.
Charns bad luck. Slave raid? You are attacking Salvadors home planet. High bounty on a single human schoolgirl? Gaige.
Tediore sells a massive number of guns to the Batarian Hegemony. They then roll out a big firmware update for said guns. Anyone who is familiar with Tediore guns should expect what happens next: every single one of the countless Tediore guns in Batarian space explodes simultaneously. Even in this story, the Batarians remain the universe's butt-monkeys.
