Games developer Com2us, specializing in mobile games, launched an open trial service of 'Aimo' last month, due to be commercialized in June. Aimo, a network game which can be enjoyed by over 1,000 people simultaneously with mobile phones, is an online role-playing game (MMORPG). There are three characters- a fighter, a ranger, and a magician. There are more than 10 skills according to the occupations of the characters. In the game, there can be contests between users. One can engage in realtime chatting with other users or transactions. In addition, one can obtain equipment for one's character from a store in town and hunt alien monsters. Aimo has all the functions of a PC MMORPG as it can relocate the game just as it is into a mobile phone.
