One spelling mistake (bold) and a few things that don't look or sound nice (underlined).

The year is 2757. The Covenant is long gone, ONI is a dominant and inspirational power in the galay and Humans are now coexisting with Sangeheili. Humans are now colonizing (Humans are now, humans are now.) Forerunner Installations. The Spartan-XI Recruits are finally nearing the completion of their training. ONI's pet Spartan, Sam Trevalyan, is about to embark on his newest mission: deliver a top-secret package to ONI Centre Ascension. All is well.
Or is it?
What are the strange figures sighted on Installation 01? What is in the package? Why are the Human and Sangeheili leaders refusing to talk? And why is Sam receiving distress calls from the long-dead Catherine Halsey, about the rescue of her and the legendary John-117?
Like any human, Sam is begging (begging to find out? dying to find out sounds better IMHO) to find out. But what he forgot was (you don't really need 'what' and 'was') that curiosity killed the cat...
Just trying to help out.
Oh I see. The Galaxy was just a typo and the rest is pretty much poor sentence structure. I see now.
