is it me or is there a major typo in KH 358/2 instead of solo-missions it holo-missions. im not sure how the hell they missed that since you see it all the time
Unless it's in reference to the missions being carried out by a hologram? Haven't played the game due to R4i issues, so can't offer an educated in context answer.
Yes, it's not a typo. It's "holo" as in hologram. Not supposed to be Solo, since the missions are not solo, they are just repeats of previously done missions, even your teammates join you.
