I wrote my first message when I just woke up so let me clarify.

When I mean I don't know where to begin, I mean in a way of how should the video flow? Should it be like a bullet list with video footage to highlight the points shown? Should I use the audio from the gameplay, or a separate music track?

As well I don't play multiplayer, so I'm not familiar at all with the multiplayer features at all and even the stuff made for singleplayer I don't fully understand at times.

I feel this would work best if I had someone more familiar with the features of JJ2+ help me to figure out a style, and what points to show in a video as trying to show everything would result in a a very long video. I think a 2-4 minute video that summarizes a lot of the main strengths of Plus would work.
