You've got to check out this incredible video that features aliens that have been inserted into some actual footage from World War I. The result is stunning, and it will probably be the coolest thing that you see all day. The video was created by PLAZMA, and it's called the Great Martian War. The video came along with a fun description on History.
On its 100th anniversary, The Great Martian War tells the story of the catastrophic events and unimaginable horrors of 1913-17, when Humankind was pitted against a savage Alien invasion.
With powerful and detailed First World War parallels, The Great Martian War fuses sci-fi fantasy with specialist factual history to explore the real-world tragedies and unique horror of World War One.
It's kind of eerie watching this and seeing what a war against aliens might have looked like during this time in history.
