I have found a few mods/addons that has to do with machines, and I wonder if anybody would like to try and attempt to make something like Terminator or perhaps the Matrix
Just a thought.
Also had an idea of something like "The Rock", have to fight your own people (well really they are traitors) and then neutralize the missiles (scuds) and save the hostages. Kinda complicated really, I tried it and I couldnt even get the intro right!
