Konami released the first Metal Gear on July 13, 1987. Created by Hideo Kojima, the stealth game came out on the MSX2 computer and went on to spawn a successful and beloved franchise. Today, fans are saying thanks.

Under the hashtag #MG30th and #メタルギア30周年 (or “Metal Gear 30th Anniversary”), Twitter users have been uploading photos, art, memories and comments. Some of them have even been retweeted by Kojima.

If you want to create anniversary fan art of your own, Twitter user Hakoriot created these unofficial 30th anniversary logos.

Happy anniversary, Metal Gear!
