Original amusement arcade sensation Space Invaders scaled new heights on its 40th anniversary as developer Taito Corp. marked the occasion with a giant projection of the game at the top of Tokyo’s Roppongi Hills tower.

The global phenomenon and inspiration for modern video gaming is being commemorated with “Play! Space Invaders Exhibition” at the complex’s 52nd floor observation deck.

The projection on the windows inside the deck is the highlight of the event, which is open to the public from Jan. 12 through the end of the month.

Tomohiro Nishikado, the 73-year-old creator of the game and former Taito employee, said during the media preview on Jan. 11, “I am happy that the game has been popular for 40 years.

“I could accomplish the work to create it because I was young, driven and strong.”

The projection, about 7 meters high and 15 meters wide, was revealed above a cityscape of the capital, with Tokyo Tower and other high-rises shining in the night sky.

Up to 10 visitors can play the game and work together to defeat invading aliens on the giant “screen” during the event, between 10 a.m. and 10 p.m. each day.

Admission is 1,800 yen ($16.18) for adults.

The Space Invaders game was developed for gaming arcades and released in 1978, soon becoming a huge hit around the world.
