I took the sound bite from Modern warfare 2. Its nearly the same sound, all i did was add a bit of silence in between the two beeps, and added an echo to make it sound like its in a factory like setting.
If anyone has a problem with me providing this sound, I can remove it.
i think it is great to have some people who are good whit sound editing etc make some more sounds to chose from,
so good job and carry on
