While Irem did not mention the current situation in Japan in their announcement, the publisher decided to cancel Disaster Report 4: Summer Memories. The game was originally slated for release this past February before being delayed twice to a "spring 2011" release.
Disaster Report 4 begins with an earthquake and like other entries in the series players had to survive afterwards. Similar to past games in the series players could collect costumes and compasses too. Crutches, an item which allows players to walk on an injured leg, and a hygiene meter were added to the series.
Irem also announced Disaster Report 4 would have 3D effects for 3D TVs and PlayStation Move support, although they didn’t explain how their game would utilize the feature.
