The Island Rescue is an open world survival adventure game. The story takes place on a small island called Konavika in the South Pacific Ocean. The beautiful scenery of the island attracts tourists from all over the world to spend their holidays here every year. Nearly 1000 people on the island live and work here. Konzern, a multinational group, has also established a biopharmaceutical research and development center here. One day, the virus laboratory in the R&D center suddenly experienced a power failure of unknown reason, and the failure was not eliminated until two days later. Because of a long power failure, the overflowing wastewater is discharged into the sewage system without being treated by the water purifier, and the deadly virus hidden in the wastewater quietly spreads across the island through the sewer.

The Island Rescue players will fight zombies and mercenaries on this dangerous island through the third person perspective, save and help virus experts to develop drugs. Players will use a variety of weapons and equipment and various vehicles to shuttle between the dense forests and towns on the island.
