THIS POST CONTAINS SPOILERS FOR HALO PLOT IN THE MEDIUM OF BOOKS
The ending of Reach was definitely interesting, and although slightly aggravating, it fitted with the concept that "You've already lost... and you damn well know it". As hateful as it is to see your legendary super soldier battling to his or her last, the fact you succeeded in your mission, gives you some comfort. Like others, I'm annoyed that Legendary didn't offer anything extra over the normal ending, such as seeing that your Spartan survived, managed to get a dropship pick up, or possibly some backup, but it didn't ruin the game for me. Still, it was interesting, having read the accompanying book series, to see another part of the fall of Reach.
It's been a long time since I read "The fall of Reach", and if I still had the book lying around somewhere I'd tell y'all a little story about the other Spartans who survived said fall. The books and the game however, don't get in each other's way, and there is a shout out to the vast majority of Spartans on Reach as "Red Team", compromising if my memory serves me well, around twenty Spartans who were tasked with defending the planet side generators for the super MAC platforms around Reach.
Through the course of the books, namely "First Strike" (How Master Chief, Sgt Johnson and a few others got back to Earth) and "Ghosts of Onyx" (Some of the other surviving Spartans during the battle for Earth ending up in a forerunner dyson sphere with Dr Halsey) At least four or five other Spartan-IIs are acknowledged to still be alive, and with "The Cole Protocol" (The actual definition of this is a protocol put in place, that UNSC ships must make a number of random slipspace jumps before heading to a human colony, so as not to provide a direct route, in case the covenant can track slipspace travel) Spartan Grey team is brought to light, essentially three of to most unruly Spartans sent on essentially black ops missions.
