Machinima documentary mode

My documentary video will be about experimenting and observing in different methods and there will be text to guide the audience along the video clip. I think it will suit the concept of "documentary" because its like a record of experiments being filmed as an education or general purposes about explosions and porosity. I will be using explosive barrels and alot of C4 to show the explosions and there will be physics involved too. Although one of the experiment will not be possible in reality but benefits the effects in game modes.
