Well, I haven't really played the demo ever since I started testing MCO. However, last I checked, there was no more than Two demo missions.
There is therefore only three possibilities for this picture:
1: The original picture was edited.
2: This is from a different Hyperkat M.C. series like MCS or another series that Hyper has not revealed or that I am unaware of.
3: This is from a different version of MCO or the demo that, again, Hyper has not released or you and I have not gotten.
In any of these I am 90% sure there is only 2 demo missions, so it is highly probable that it is 1 or 2.
Otherwise, I do not know and cannot anwser your question.
Of course, that is just the assessment I can make based on what I know. Hyper or someone else more experienced than me would probably be able to anwser your question beter.
