Resident Evil 3 Secret Ending Scene at Control Room

There is a hidden ending scene on this game. For make it happens, you MUST choose "Jump Off" when you encounter nemesis on the suspension bridge. Later in the game you will find Nicholai trying to leave the place by chopper, you can destroy the chopper or negotiate with him (it's up to you) but let him go is the cannon scene. After that, Carlos will come in the Control Room and talk with Jill. When they finish talking, DON'T check the ladder (just leave the room by opening the door and then return to it again) a cutscene will happen about someone trying to contact Jill on the Radio. Now you can leave the place by going downstairs, defeat Nemesis final form and go to the Scrapyard, it will happen an alternative ending scene.
