cientificos desaparecen: Scientists Missing
En el avión:
Good day, Agent SLASH. This time, your mission is to investigate the disappearances of scientists all around the world. Our investigations have confirmed that...
they have been taken to a remote island in the middle of the ocean. You must deactivate the fortress from within and find the scientists. If they are alive...
You must return them to their respective nations. Also, we must inform you that you will undergo some physical changes upon drinking the Virus Z-206.
Within time, your body will adjust, and you will gain NEW ABILITIES as a result.
Again, Agent SLASH... We leave it in your capable hands.
Confrontación con Vector:
SLASH: Vector! So you're behind all this!
Vector: SLASH, we meet again. You're still alive!!!
SLASH: You won't get away with this!!!
Vector: Silence, fool!!! You will now suffer for your loved ones. Meet... My 5 Generals. I used those scientists to develop the ultimate warriors, so that I may conquer the world.
SLASH: Vector! Stop!!!
