did the guy ezio died next to kill him or did ezio just have a heart attack
They were building suspense that he was going to be killed by the dude, but Ezio was spared by him and instead suffered a fatal heart attack.
why does installation 04b kill flood when a pretty big plot point of combat evolved was the fact that halos do not kill flood, but rather their food?
If something gets hit by a massive blast of radiation, it's probably still going to die. The thing about "killing their food" is that The Flood will always come back; only one spore needs to survive for The Flood to return to full strength, provided there's a source of food to chow down on. The Array can't guarantee total annihilation of every single Flood spore, but they can ensure the end of everything they would eat.
Keep in mind, Installation 04B (also known as 08) never actually fired. You turned it on when it was absolutely not ready, overloading the core and making a massive explosion that blasted the forget out of the current Gravemind and his army. It's not a guarantee they're totally gone forever, but a Gravemind lost means that any surviving Flood in that sector would be uncoordinated and confused.
It probably didn't help that Alpha was also a research facility that was storing and protecting. Flood inside
why are the spartan IIIs in halo reach wicked stronger than the ones in ghosts of onyx
It's likely two things; firstly, Reach is the homeland for many SPARTANs. It's their most sacred of spots, and so if anything forgets with it, you guarantee the SPARTANs are going to push back as hard as they absolutely can to protect it.
The other thing is that SPARTAN IIIs aren't as consistent in quality as SPARTAN IIs. They're made relatively cheaper from much older candidates who don't receive as much extensive training. This means the skill level can be wildly dependent on how good a candidate was before they were given the SPARTAN treatment. Noble Team was one of the specialist groups. Best of the best. You're playing on one of the few elite teams who are required to pull off miracles that the UNSC command don't trust other squads to do.
why am i so loving bad at grenade jumping
Timing an coordination. Just need more practice, and you have to be sure to only try with Frag Grenades which give you the biggest blast radius. You may also want to try the Brute Shot in Halo 2 onwards, as that might give you a bit more precision with aiming the blast.
Have you heard of the high elves?
They exist in many franchises.
Why does humanity still use mostly bullets in Halo while being hundreds of years in the future
Physical bullets/kinetic weapons can offer more destructive force for less energy cost. You'll note that a core part of Halo is that Covenant weapons strip shields, while Human weapons deal quick health damage.
Are the people who make up the reaper still thinking and part of the reaper?
Like can they still communicate and becoming immortal in that way?
Not exactly. When a Reaper is created, thousands (maybe millions) of a Prime species' people are put into special pods. When they're connected to the creation chamber, the pods are activated and the subject melted down into a goo substance maybe up of their primary components. The goo is then filtered, and only the necessary genetic compounds needed to make the core run are left behind which are transferred into the core.
It is likely that an individual's genetic material adds their "voice" (or at least their memories) to the whole of a Reaper, but I doubt it's a literal thing. It's more like everybody's individual thoughts are splashed together alongside some Reaper programming.
Is Andromeda canon?
It is considered Canon, but you can easily justify it as a spin-off, like the Star Wars EU.
why did they think cortana as a bad guy was a good idea
Cortana had almost reached 7 years old at the end of Halo 3. She was about to go rampant. Bungie left this plot thread open in case anybody wanted to do a sequel to the trilogy, and so it was natural that 343 wanted to make use of it.
Rampant AI aren't friendly. They think they're better than those around them, and do some pretty insane stuff. I don't like the way 343 wrote Cortana's rampancy phase, but it was the path they had to take.
