The Metal Gear Solid saga, which Kojima directed, produced, designed…

“I wondered if this might be the system where I could realize my original, full vision of Metal Gear… and the game that has emerged from that is Metal Gear Solid.”

Kojima created and directed the video games Metal Gear (1987), Snatcher (1988), Metal Gear 2: Solid Snake (1990), Policenauts (1994), Metal Gear Solid (1998), Metal Gear Solid 2 (2001), Metal Gear Solid 3 (2004), Metal Gear Solid 4 (2008), Peace Walker (2010), Metal Gear Solid V (2014–2015), P.T. (2014), Death Stranding (2019) and Death Stranding 2 (2025); he has OD and Physint in development. He has also produced or supervised other video games such as Zone of the Enders, the Boktai series, Castlevania: Lords of Shadow and Metal Gear Rising.

In a September 2011 essay, Kojima wrote that each time a new Metal Gear came out he declared to the press that it would be the last he would make. He explained that all stories and all creators have an end, and that he wanted to bring his own story to its conclusion before he reached his.

Kojima spent almost three decades at Konami, beginning in 1986. In 2015, amid a bitter split, Konami removed Kojima's name from Metal Gear Solid V marketing; at The Game Awards in December 2015 the game won awards but Kojima did not attend, reportedly barred from attending by Konami. That same month Kojima re-established Kojima Productions as an independent studio partnered with Sony. Silent Hills had been cancelled in April 2015.

“Every game I make, I create thinking it's really, really going to be the last game I create. So I put as much as I can in and make sure I have no regrets.”
