Ok, now in order to make that into a mission, I'll have to make some slight changes:
1) The command centers can't be against the wall like that, op2 won't let you build buildings that close to walls.
2) You did nothing with the cell type layer. As it is, the lynx can go anywhere despite the walls. The graphics are just pictures, you need to paint impassible cells onto the map too. (it's the third button on the menu bar, read this too if you ever make a map again:
http://wiki.outpostuniverse.net/Cell_Types). I'll fix it for this map though (since i already have it).
Also, what are the advanced labs for in the top left? And, do you want the walls to be normal walls? Meaning, can you shoot them to destroy them?
I'll make the mission file (dll) when you can answer those questions, and I have some free time.
