So I'm going to make some fanfic which will follow the events of Halo 3, so here goes As Master Chief floats through space aimlessly, a planet approaches, hurtling towards it at 500mph, he breaks through into the planet's gravitational pull. As he breaks through the atmosphere the sheer velocity of the fall starts to vaporise his armour. Then with a sickening thud, he hits the ground, creating a crater the size of a house. An old man walks over and attempts to wake Master Chief up.
The old man finally manages to wake up Master Chief and asks "What the hell happened there?!" "Well that's called me being smashed into a big rock called a planet" Master Chief had a slight dislike for this man already, "and where am I anyway? And why do you know English if this planet isn't Earth?" "Well, my friend, this planet is called Hope and is the 4th planet in our solar system, and we know this language because we found it millennia ago written on a chunk of rock from space, from then on that is our language" "okay then, do you have a workbench, some titanium and some wiring that I could use?" "yes, follow me" the old man walked about a mile with Master Chief until they came across a warehouse "this is my house, it has all that you need inside" Master Chief removed his armour and started repairing and altering it slightly, then he remembered Cortana, she died but with these spare parts he could re-boot her and gain access to the plans for the Spartan 7 program and design his armour accordingly.
After the armour was built Master Chief (whose real name was John) took a stroll around the small village he landed next to. He walked around looking at all the small houses and wondered what sort of technology this planet had when he stumbled across a gunsmith. "Umm excuse me but I was wondering if you could help me" "oh hello, welcome to my gunsmith, my name's Dan" "hi, may I see your merchandise?" and as John said that he was taken to the back of the shop by Dan and was in a state of awe at the sight of the technology, there were upgraded DMRs and snipers with suppressors and night vision scopes, he purchased a DMR and walked out, that was when he saw another prophet, in the woods.
The prophet was just sitting there looking blankly at a tree, John raised his DMR and just before he shot a Sangheli assassin pounced on it and thrusted an energy sword through it's neck. The elite then saw John and walked over to him in a proud strut "Your a Spartan, aren't you?" John was shocked at how the Elite spoke English "yes I am, why?" "well then, follow me" "I need to get my armour first" John got his armour and followed the Elite, they walked for about 8 hours and finally arrived at an army base, John was greeted by the general and as he did so a Brute charged from the forest towards the Elite, but was stopped as a bullet passed through it's head. Out of a tree jumped another Spartan and removed his helmet, it was the gunsmith, Dan. "nice to see you again 117" "how do you know my issue number?" John replied with a bitter tongue. "because your the only one that survived The Fall of Reach that didn't escape to here, Hope" "okay then, what's your rank Spartan anyway?" "I'm a commander, and your Major, if I'm correct?" "yes sir" John and Dan then followed the general through the camp to which they found another Spartan "the name's Fletch, don't underestimate me" "these are our remaining Spartans but before Reach fell we acquired some technology and are in the process of making more, you three are now officially now a squad, you will be referee to as Alpha squad, Dan will take charge and Fletch will be his second, John, your Dan's third, he has plans for you, oh and just to let you know Fletch is a Sniper and Dan is a Recon soldier, this is your first assignment" the general threw a folder towards Dan and Alpha squad read the information.
Look for a summary of the whole Halo story on the Internet and Reach was a human controlled planet stronghold which was taken down by the covenant but has nothing to do with the initial story of Halo
No way u are totally wrong halo four starts out with chief hearing cortana yell "chief!" and then John got out of the Cryo tube and finds a pistol mixed with rocket and the frigate is exploding. Then chief uses a jet pack thing on his armor. He boosts out of the frigate and blasts a barrier in front of him. Once outside the frigate, Chief gets on the side of it and (somehow) loads in a rocket into the pistol (like he'd have ammo). He looks upward to see a gigantic blue light above him. That's all I know about halo four now. I've only seen the trailer, I don't have the game so your story is completely wrong you dumb***
