I was making a point, never claimed any building in Chernarus had this technology

My home's security system is solar powered, built for power outages.

Well obviously so, however, there's no fun in that... but some houses have security systems that would alert the zombies!

This idea is mainly aimed towards DayZ Game but would still be nice to see in the mod. Since not all doors would be unlocked in a real zombie apocalypse, add locked houses. A certain zombie in the town would simulate the house's owner. - Have a rare chance for a locked house to spawn (although not as rare as crashed helicopters) - Kill surrounding zombies for key to unlock door - Locked houses would give higher loot chances that are untouched by other players - Once a house was unlocked anyone would be able to enter This would give a use to killing zombies, make going into smaller towns more beneficial, and players could work together to get inside.

No no no

You don't need to rebuy Arma2, only OA. And yes to answer your question.

It's the Titanic all over again

To find your player ID run Arma2 and go to your player profile. It should say there.
