> Assault on the control room is my favourite level. On legendary I can save 10 marines, though it is hard. You HAVE to save Sarge, he provids such hilarious commentary. If you can get sarge and 2 or 3 marines alive they’ll say funny things.

> T&R on legendary is where skill comes in, with no pistol and limited sniper ammo, you’re dead meat if you spend it all before getting into the ship. The marines are cannon fodder, but this level is what REAL battles are like: Hard, near impossible to keep your marines alive. Battles like this, or once inside against all the invisible sword elites, or in Halo at the first holdout site where 5 or 6 spirits drop reinforcements. Afew times I have saved all the marines there, and in Truth and Rec I got all 5 marines from the grav lift to the bridge though that only happened once and they said to each other that they were hurt bad. All this on legendary mind you.
H1, where allies actually matter and where battles are actually life threatening, where you’re forced into cqc.
In H3 and Reach, I find myself wanting to kill marines. And it is extremely frustrating (not challenging. Enemies only contribute to their demise) to keep them alive since they drive off with vehicles and charge into battle. Their incompetence is the most appalling thing I’ve seen in a video game. I often find myself resorting to long range since I have no one to rely on (mostly in Reach. In H3, cqc is still possible, although extremely risky unless you have someone like Arby around).
> In 343 Guilty Spark one memory that stands out is when you find a pile of dead bodies, human and jackals who have clearly been fighting alongside each other against the flood. It always makes me sad seeing how against certain death they put aside that hate to fight against the common foe.
The only game where they set aside their enmity.
In H2 and H3, you know you’re going to get screwed in those mix-up fights if you don’t kill them all (Gravemind was disappointing for this reason. I would have liked to fight with those Ultras but I have to kill them to get the door to unlock. I would have liked to leave them alive and just sneak past them). In H1, you can actually fight alongside the Elites (notable moments include that battle on Keyes on the other side of the gap) and live to tell the tale.
Also, marines are like automated turrets. They see a Covie, they shoot and kill them. There’s no consideration at all, even if the enemy is unarmed. It’s disturbing (and annoying because I like having unarmed enemies).
> On the same level, on the dual bridges connecting canyons, if you throw grenades at elites they’ll evade and sometimes fly clear off the bridges to their deaths! 
It feels the most rewarding when Goldies do it imo.
> There is a part on AOTCR where grunts are sleeping. There are afew, but one in particular where its all grunts and jackals, if you get all the grunts in one hallway and poke your head out, especially on legendary where you get the most grunts and they’re at their most tenaciousness, they will shoot each other to death by accident and call each other names. It’s so funny.

> Another part is in the same level where, actually afew parts, where you reach the control room pyramid on the bridge with the banshees where it says If I Had A Super Weapon… With the camo on I melee the first grunt on the left off the bridge and if you’re lucky he will say “What the?!” then as he goes down “Noooooooo!!!”
> OMG I lauge my -Yoink!- off everytime I hear that. Once you get down and see the sleeping hunters I get them to follow me in their feeble attempts to beat me up. I stand right in front of a sleeping grunt and let the hunter melee it. 3 hits to kill a Major, 2 for a Minor. It’s like grunt baseball, if done correctly the grunt will go flying! HOME RUN!!!
I have to try these!!
