ODSTs dropping in (Halo 2 and Halo 3 ODST has this)
Creepy entrance (343 guilty spark (level in which you first meet the flood)
Only keyes is bad–Yoink- enough to ram a pair of Hunters with a covenant dropship (ending cutscene of Truth and Reconciliation)
That grunt just wet itself (beginning cutscene of assault on the control room)
Yes Cortana he did that on purpose because he is bad–Yoink- (beginning cutscene of the maw)
I thought grenades were smaller than that? (second cutscene of the maw)
Tell that to the covenant (The Heretic)
Fire your guns its time to run blow me away (that battle between covenant loyal to elites and covenant loyal to brutes in the mausoleum of the arbiter in the second to last Master Chief mission of Halo 2 and yes I know it is not a cutscene but still)
Yes half jaw, being outnumbered by brutes three to one is fair but then again I guess Elites would think that (beginning cutscene of the Ark)
My single favorite scene is immediately after ONI Alpha Site in ODST, where the Rookie just watches the burning skyline of Old Mombasa across the water and the Orbital Tether.
In all of Halo, its probably every Cutscene where the Chief speaks. And the bits where Halsey speaks. And Miranda Keyes’ death. And Sergeant Johnson’s death. And 343’s death.
