Hunt vampires and harness the elements in Lunar Knights for the Nintendo DS. A spiritual successor to the Boktai series, this action RPG features two playable protagonists: Lucian, a vampire hunter wielding a dark blade, and Aaron, a gunslinger using a solar gun. Unlike its predecessor, it simulates a weather system on the top screen that directly impacts gameplay; sunlight powers Aaron, while moonlight strengthens Lucian. You must switch between characters to solve puzzles and defeat bosses in isometric dungeons. Afterward, take to the skies in 3D "casket shooter" segments to purify the vampire souls. Restore the planet's climate and defeat the Duke in this polished handheld adventure.
