From the sprites to the isometric camera angle, Otodamster for the Nintendo DS appears to be an EXE knock off, but in actuality, it's far from it. Other than the graphics, Otodamaster has nothing in common with Rockman.
What is it? Otodamaster involves the act of catching various monsters for use in combat. Sounds like Pokemon, right? Sort of. From here, things get really interesting: in order to catch creatures, you have to utilize the DS microphone to pick up sound. Simply hold up your DS to a barking dog, a car horn, a blender, or anything that makes noise to successfully make a catch. The better the frequency, the higher chance of a catching a desired creature.
Unfortunately, the title has yet to see a release outside of Japan's shores.
