[quote=8bitnintendo]That’s true, but a group of 3-4 people could get by with some concertina wire and perimeter lights to keep the zombies in place while you go for a headshot. Zombies washing up would occur only sporadically, and (assuming your island is not visible/audible from the mainland) you will not have waves of purposeful zombies. I like this island idea and am willing to contribute my efforts to this venture. Who’s got a boat? :)[/quote]
8bit: Actually, there are some excellent next generation automated defense systems out there right now that would fit the bill. Single or twin .50cal M2 heavy machine guns hooked up to intrusion detection sensors on your perimeter fence or wire. We’d have to stockpile a shitload of .50cal, but its a completely automated system. Saw a live demo for one of these recently and it was pretty friggin’ impressive. Twin .50cals hooked up to a thermal imaging and CCTV system and run by a remote control operator over a mile distant.
