Taito is showing off a new four-player light-gun arcade game in Japan called Gaia Attack 4 -- the "4" represents the number of players, I believe, and not the number of Gaia Attacks. I'm pretty sure this is the first time these aliens have attacked Gaia/Earth!

As Arcade Heroes points out, the game overlays CG effects so you're shooting on top of real world footage. You'll see alien ships, creatures, and mushroom things taking over recognizable locations/monuments like the Eiffel Tower, the White House, and, um, a microwave.

Make sure to watch until the end for the moonwalking aliens dancing along to a Will Smith soundalike.
