Solo is ok. im not to impressed with it tho. The music isnt as epic as the past halo game IMO...and there are some parts where the music doesnt make sense to whats going on. I dont know about you guys..but me and my friends have had some issues with checkpoints not loading or not saving.
I was hoping for more back story of the Spartans and well more mission. The solo is good but i was expexting more. CO OP is still fun though.
