The principle of cause and effect will be quite important in the upcoming Crysis 3, at least if we have to judge from the new trailer released today.
The spectacular video shows Prophet while he attacks a hidden power station controlled by Cell in the middle of what used to be Wall Street. The peculiar element is that the whole trailer is recorded in reverse, giving it an interesting overall look that is quite effective in demonstrating just how cause and effect interact.
You can check it out below. I also added a reversed version that shows the trailer with the correct time flow, courtesy of Youtube user VGWoo.
