Boktai

In 2003 Kojima produced and designed Boktai (Game Boy Advance), whose cartridge included a photometric light sensor; to charge the game's solar weapon the player had to take the Game Boy Advance outside into real daylight, which compelled playing outdoors and during the day.

“I actually had wanted to include a sensor that measured how your breath smelled too! I *really* wanted to add that! The enemies are vampires, right? So if you ate something garlic-y and breathed on the mic, they'd all die. (laughs) [...] "Guys, we have to do this!!" But the rest of the staff all hated the idea.”

“You can't ultimately win against that void of nothingness that is space—victory's just not in the cards. And yet still he fights. I think this is actually a pattern that re-appears in all my games, the concept of a battle that's a lost cause. (laughs)”

“Well, this isn't fake news, but every single day from all over the world, I get messages saying, hey, make a new Metal Gear, or PT, or Boktai, or Zone of the Enders. I take this as a positive thing, but also, as adults, everyone should know that this isn't going to happen, right?”

“I think it takes 3-5 years for a game to receive proper evaluation.”

Besides Metal Gear, at Konami Kojima produced or supervised other games: he was producer of Zone of the Enders (2001) and of Boktai (2003), executive producer of Castlevania: Lords of Shadow (2010) and supervising director of Metal Gear Rising: Revengeance (2013).

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.
