So you want a sequeal? I think that's the best way, that way the story can be easier to remember and understand
So now we can decides which character will probably survive the zombie island 2, it could be all, or some alone with new characters.
So I am guessing the story will some what be like this.
At the big finale,some suvivors manage to escape the island and tell the world of the zombies, but the companys cover up push away all the doubt from the outsides, and authority unable to fully clean up all the zombies , retreat nuke the island wiping most of the zombie out, but sadly the radiations only mutate the surviving zombies into even more vicious and now threatens to attack the city near the mainland. And the company are again caught in it and the survivors moves to the city as temporary refugees but are forced to fight the zombies again and the authority this time are gona to use a WHOLE bunch of heavy weapons.
How's that???
And as to who had survive the zombie can be voted? Like who should be dead or alive. Something along that line.
The map should be somewhat close to now, maybe if happens on mainland no waters and the survivor's condition would have beening different.
Maybe this time the survivor can have the space victory, having to final uncover the mask of the company's deed and having company the victory point condition as kind of spreading antidote from a hill/tower to acheive victory. That is they will not only save themselves but makes a whole bunch of the money in the process.
The authorities might also have too stick to the conquest. But this time more weapons for them. Units impossible for them to get on the island. Special Forces, heavy rockets launchers and helicopters. Maybe they can't use nukes because they are afriad the radiation might make the zombie stronger and a negative opinion and effect for them. So they need stronger units to balance it out.
