When I get access to my computer that has OP1 installed, I'll tell you how I did it.
And you don't need to know too much about programming to make OP2 missions.
There's stuff to do besides coding, though. Like mapping... Which makes Death sound not all that bad (if you haven't mapped yet, you'll understand as soon as you try).
I have a great admiration for people who have the dedication to make a good map.
But that's all a bit off-topic.
I do remember that you need to build several structures in a very specific order or the game crashes. I'm pretty sure you need to build a Monorail Power before you build anything else. Also, for some reason I think the Mass Driver is somehow involved.
Well, good luck!
