I’d highly suggest playing it with a friend and on Legendary. It’s a lot more fun that way, IMO.
Also, if you’re looking to complete commendations, you can get all of the Enemy ones from Spartan Ops. Though You’ll have to do some grinding for a couple of them.
Also, Covenant vehicle commendations can be achieved EASILY through Spartan Ops. So no need to try for them in Matchmaking.
Personally, I absolutely LOVED playing through each mission. Yes, some maps were used, but not in the same way or following along the same path in most cases.
In the latter half of the season, all of the maps changed to new ones. Oh, on that note, people keep arguing about SpOps having the same maps. Let me make an analogy here.
Reach Firefight = 10 maps. Same defensible positions each time.
Halo 4’s Spartan Ops = 15 maps reused and repurposed for differnt missions.
Also, as a matter of fact, in real warfare, there are many times where the same area is fought over time and again. I saw this while as a field medic during the Gulf War. It was MUCH more prevalent in World War II.
So the reuse of maps was very logical and of course it made it easier for 343 to get missions out each week.
So once again, I HIGHLY suggest playing it and more so with a friend and on legendary. It’s a whole campaign unto itself!
If you want something a little different, I created a Spartan Ops graphic novel from all of the Episodes. You can download it from here: Spartan Ops Season One Graphic Novel completed! (all 10 episode comic books in one document) | HaloFanForLife
I actually created a comic book a week using the cut scenes. It was somewhat popular then and was showcased on Waypoint. The graphic novel is the same as each comic, however includes MORE stuff in it.
Hope this post helps in your decision to play it.
