The first 2, "enemy see's me, he shoots" are already part of the existing scripts. The 3rd one, "an alarm rings" is just a matter of adding a "sound=" command to it, and "the game ends" was just done by candle_ in another thread today. (see thread call "die and fail")
Just put them together. If you try and can't get it right, someone will probably help you. Otherwise, just asking people to make your specific scripts for you probably won't get you far.
Best of luck.
