If you've played Halo 3 (only on the Xbox 360 gaming console sadly), then you might have come across this before - it's the Rat's Nest (not literally!) multi-player map, in Lego-style of course!
It's space-age marines blasting aliens in the eternal struggle of humanity's survival! This awesome scene by Vidgamer838 about the Rat’s Nest (Halo Wiki) map captures this scene.
