This is a video from Rooster Teeth of a group of people playing a real life game of Space Invaders. The people playing the aliens slowly advance and throw balls trying to destroy the cardboard defenses, and the defenders move along a straight track shooting the aliens with a cannon. I would definitely pay a quarter to play that at the arcade. Maybe even fifty cents if I did all my chores this week and earned my whole allowance. I'm gonna be honest, it's not looking good though. Making my bed is hard.
Keep going for the video.
Thanks to Jamie, who wants to see Centipede recreated in real life.
