While the 30th anniversary of Mortal Kombat's release may not be until next year, this year marks 30 years since development started on the iconic fighting game, as co-creator Ed Boon pointed out on Twitter. The developer, who also voiced Scorpion in the first few Mortal Kombat games, has used the anniversary to share a behind-the-scenes moment from the classic game.

A video posted by Boon shows filming underway on Scorpion's movesets, capturing footage that would later be digitised into the game. During the session, Boon can be heard spitballing on a new move, beginning with an excited "you know what would be a cool-ass move?"

What came out of that improvisation was Scorpion's spear, better known as the "GET OVER HERE" to most players, thanks to Boon's voice lines. Boon explains that, despite how the video appears, a lot of prep happened before the video shoots, but the developers still sometimes improvised moves on the fly. Throughout the two minute video, you can see the off-the-cuff suggestion quickly being refined into what has become one of the franchise's most iconic moves.
