It's like 'Knightmare' for grownups in the 21st century. We want a go immediately.
For the most part, watching other people play video games is usually a very tedious affair but this game set up by British film company Realm Pictures is not like normal video games. Their first person shooter game took place in their garden, and was controlled by people on Chatroulette live over the internet.
Confused? It's easier to watch than it sounds (and if you want to see how it was all done, they have a handy behind-the-scenes video too).
While we're at it, we'd also like to mention that we 100% support a return of 'Knightmare', if someone wants to get on that.
