My opinion on spartan ops is that is that it is boring.
Very repetitive.
little to no replay value
way to easy with the unlimited lives(very easy even on legendary).
no scoring system.
not fun and not built to play by yourself.
cutscenes are lame.
doesn't explain things(why are the prometheans still red if the didact is dead,because wasn't it when the didact regained control that they became red.
why do we have to play as some lame sideline character named crimson.
every mission feels like some petty errand.
most missions end with just clearing out the same enemies over and over.
Great game 343 but spartan ops is in my opinion is pretty crappy . That about sums up the whole spartan op experience.
