International Rescue Operative is one of the endings in Fleeing the Complex.
In this ending Charles rescues Henry from The Wall with his helicopter, after having helped him dispose of a guard first. This ending follows on from Government Supported Private Investigator from Infiltrating the Airship as Henry is still on good terms with the Government.
How to get this Ending Edit
Henry needs to wait for transfer. Once in his cell, he has to use the laser plane to reach the room below his cell, and from there call the Government for help. Charles crashes his helicopter into the Wall, destroying the prison and freeing Henry. This gives you the Kamikaze Escapist ending.
