Zombie plan? What zombies? Now, if you're talking about the massive Zaibie horde out there...
I'll just be in my barricaded house with the turrets from portal surrounded across my house. And if they somehow get through them, they'll have to get through my portal'd out ground. If a zaibie falls in a portal on my lawn, they will be shot out in the ocean where they will die. And my entire house is covered with portals going to the ocean.
If they somehow get through that, I'll have a nice shotgun waiting.
