You use on too much, and in situations it doesn't fit. Look up the definition of on and its uses. That's the only error I caught, otherwise this is a nice first chapter. .

Okay...WAS THAT JORGE!? HOLY MOTHER OF FIOHIGIJGIOJJIFJ. Good God, That’s awesome. Please update soon...and have Jorge come in (at least, that’s if my suspicions are true).

Is this how you're going to update this story? Only once per year? Sorry man but I think it's best quit being a crossover fic writer as this stuff is no longer going to be a hobby but detriment to yourself and your life especially if you're going to make this fic more than 24 chapters by updating per year. Its best that you leave a message to your readers as that you've quit to help you're readers move on.
I'm not saying this because your a terrible writer but rather out of concern in going forward with your life man.

This is making no sense and you killed cortana. Not cool. At all.

Amazing story please keep going don’t stop and please stay safe

Nice Story! I was wondering will the covenent show up in the IS Academy?

Please continue

This story needs to be labeled OOC John for sure. He’s a spartan from a 30 year long war where he was on the frontlines and doing the impossible he should be a quiet stuttering mess he should be cold and tactical that’s what he is he was trained as a damn spartan and is a hyper lethal he is one of only 2 of them he shouldn’t be acting like a baby kinda kills the story in my opinion

Awwww but giant John is best

This story is good but it’s got so much stuff that I just don’t care for. I know why it’s there but it’s so boring I wanna see John do shit not be unconscious and boring he’s a hyper lethal and no way in fucking hell would anybody ever be allowed to take his armor from him

Very unique story. i look forward to the next chapter

so you did not die

I highly doubt they would be able to replicate the process to create forerunner grade armor because if the unsc couldn't do it yet i highly doubt they could , other wise the unsc would have put forerunner grade armor on their ship or the spartan 4 armor and keep in mind that the unsc had access to forerunner technology and armor for years because of portal to the ark and the captured halo rings and the keyship that still on earth and Onyx.
