...it seems to be an collection of missions thats named a campaign by 1c
I am not sure what you mean.
I suppose he feels the missions are more or less unrelated to each other and would be more accurately labeled a collection of single missions instead of campaign. Usually a campaign will have several areas linking all the missions together, although this can differ depending on the author.
I've not tried it so I can't comment on it myself.
