I just thought i would write this dowb because it is not specificaly given
in any of the other cheats even though it is branching off 1 of them what 
you do is when you are doing the invade corporate cheat dont just do it 15
times do it more than that and you will be available to invade any of the 
places even the "coming soon" ones i read the corporate 1 and i had already
done it but it but i hit the invade button about 25-30 times and that is 
what happened not just the corporateville.
