Vectorman 2 is a somewhat darker sequel to the original game involving the same hero — "orbot" (robot made of orbs) named Vectorman — saving the Earth from being taken over by another crazed orbot named Warhead.
In this sequel, Vectorman's sludge barge gets suddenly blasted by a missile. He escapes and ends up in a place infested by mutant insects led by horrendous Black Widow Queen, whose plan is to… right, take over the Earth and kill all humans, as expected. :)
