Following in the wake of Disaster Report 4 being cancelled for the PlayStation 3, developer Irem has announced that the entire series will be discontinued due to the recent earthquake and tsunami that rocked Japan.
The company will not create any more Disaster Report titles and are discontinuing production of any previous entries in the series such as DR or DR2 for the PSP. While this is disappointing to fans of the series, this is the right move in light of what happened in Japan. If you want a copy of one of the previous games, you might go and try to find them now before prices get too out of hand.
