Mister Mosquito (Mr. Moskeeto in the PAL version and Ka in the Japanese version) is a video game for the PlayStation 2. Originally released only in Japan, it was later released worldwide. Made up of a series of stages, which, rather than automatically running through like most other games, must be unlocked in order by completing each previous stage. The player can choose their own path through the stages; useful for going to any level to collect missed bonus items. Before each stage is a briefing of sorts, detailing the room where the stage takes place, the victim and area(s) on their body from which blood can be sucked and any prevalent
dangers.
The player controls a comical cartoon mosquito ('Mr. Moskeeto'

and the goal of the game is to stock up on blood through the summer so that you may survive the winter ahead. To this end Mr. Moskeeto has taken up residency in the house of the Yamada family: father Kenichi enjoys flower arranging, mother Kaneya is a hobby photographer and teenage daughter Rena is a student whose hobbies include progressive jazz and martial arts.
