Boktai: The Sun Is in Your Hand is an action role-playing adventure game developed by Konami Computer Entertainment Japan and released for the Game Boy Advance in 2003, with Hideo Kojima serving as its creative force. The game centers on vampire hunting and incorporates a distinctive hardware feature: the cartridge contains a built-in solar sensor that measures real-world sunlight and translates it directly into the game world. The protagonist's primary weapon is a solar-powered gun, meaning the amount of sunlight available outdoors determines how much power the weapon generates in-game. Players who spend time outside in sunlit conditions gain a meaningful functional advantage over those who play in low-light environments. This mechanic ties physical surroundings to in-game performance in a way that was highly unconventional for a handheld title of its era, blending the outdoor experience with the progression and combat systems of a traditional action RPG.
Following in his father's footsteps, you play Django the vampire hunter, who uses the power of the sun to defeat the many evil beings that infest the world. Search out the various levels for the evil inside, and destroy the immortal that rules the area to complete the level.
