The game that sold over 1.4 million units worldwide in its first incarnation is back - bigger, brighter and wilder than ever. Once again you have your hands full, trying to find and capture a horde of rampaging, playful primates across a wide range of fantastically varied levels. They have a whole new range of tricks up their sleeves - and you have some new gadgets to help you, and a new hero to control: instead of Spike, the hero from the first game you"ll control Hikaru. Or at least, you will to start with...
The Professor, away on a trip, leaves a video message for Hikaru, telling him to transport a large delivery of monkey pants to Monkey Park. Hikaru accidentally manages to include a number of Peak-Point Helmets with the pants. Peak Point Helmets and monkeys don"t mix: they increase their intelligence and give them ideas above their station. Needless to say, as soon as Specter, the monkey leader, puts a Peak Point Helmet on, he starts hatching plans for world domination, to make a society fit for monkeys to live in, and declares war on humans. Meanwhile several other monkeys also don the helmets and escape from Monkey Park. Hikaru is scolded by Natalie for allowing this to happen, and ordered to catch all the monkeys.
