* The Chief using a dead Geth Juggernaut [[GrievousHarmWithABody as equal parts shield and battering ram]] to knock over other Geth in the Therum ruins.
* Tali [[spoiler: [[BigDamnHeroes saving the Chief]] from a rampaging Brute and making [[YourHeadAsplode its head explode]] [[ThereIsNoKillLikeOverkill with dozens of pistol shots]].]]
* N'Tho's weapon: a Needler Shotgun.
* While explaining the Pilgrimage to Chief, Tali gives him an [[OffscreenMomentOfAwesome anecdote]] about how Kal'Reegar brought home a Brute Gravity Hammer as a gift to the ''Rayya's'' Captain. Reegar was reportedly very injured in the process of acquiring it, and when Chief asks exactly ''how'' he did so, Tali says that he [[MathematiciansAnswer laconically]] replied "[[NoodleIncident It wasn't easy.]]"
* Garrus giving Dr. Saleon a KarmicDeath.
* In Chapter 30, Saren gives a rather damning TheReasonYouSuckSpeech to the Master Chief. Not only does it break the Spartan's infamously [[TheStoic unshakable composure]], but it also riles him up enough to break his concentration and allow Saren to nearly [[CurbStompBattle Curb Stomp]] an otherwise unstoppable OneManArmy.
** Chief's response to said speech and beatdown is pretty awesome as well: [[spoiler:the second Saren gets close to deliver the ''coup de grace'' with his pistol, he swiftly and painfully learns that for all his biotic power, physically he's a BadassNormal against a [[SuperStrength Spa]][[SuperSpeed rta]][[SuperReflexes n II]]. In one short paragraph Chief decisively ends the fight.]]
* Pretty much all of Chapter 31. We get a ''huge'' battle sequence with Saren's army vs. Forerunner Knights vs. The Flood vs. Master Chief's squad, the first three of which team up to take down Chief and co once he's rescued. [[spoiler:They get [[CurbStompBattle curbstomped.]]]] And then, to [[spoiler:stop Saren from getting away]], Master Chief performs the Mass Effect equivalent of a [[spoiler:FastballSpecial, with help from Liara.]] And to wrap things up, [[spoiler:after Saren gets away]], the squad madly dashes back to the Normandy with the looming prospect of [[spoiler:a radiation induced implosion of the Registry]] hot on their heels.
* Chapter 33: There are [[spoiler:Vanguard Hunters]] now and it's as awesome as it sounds.
* They're back in Chapter 40. '''And kill a Geth Colossus without taking a scratch'''.
* When confronting a small army of Rent-a-cops at Lorik Qui'in's office on Noveria, The Master Chief uses equal parts BadassBoast and TheLongList to explain all the shit he's been through in his life up to this point and then asks them if they expect to do any better at killing him than The Covenant, Flood and Geth did. After pistol-whipping Stirling, who [[SuicidalOverconfidence still likes her odds]], [[YourCostumeNeedsWork thinking the Chief isn't the real thing anyway]], the guards not only flee, but half of them wait patiently at the elevator because the other half leave without them.
